dotnet/dotnet - Home of the .NET VMR

This repository is a Virtual Monolithic Repository (VMR) which includes all the source code and infrastructure needed to build the .NET SDK.

What this means:

• Monolithic - a join of multiple repositories that make up the whole product, such as dotnet/runtime or dotnet/sdk.
• Virtual - a mirror (not replacement) of product repos where sources from those repositories are synchronized into.

In the VMR, you can find:

• source files of each product repository which are mirrored inside of their respective directories under src/,
• tooling that enables building the whole .NET product from source on Linux platforms,
• small customizations, in the form of patches, applied on top of the original code to make the build possible,
• [in future] E2E tests for the whole .NET product.

Just like the development repositories, the VMR will have a release branch for every feature band (e.g. release/8.0.1xx). Similarly, VMR's main branch will follow main branches of product repositories (see Synchronization Based on Declared Dependencies).

More in-depth documentation about the VMR can be found in VMR Design And Operation. See also dotnet/source-build for more information about our whole-product source-build.

Goals

• The main purpose of the dotnet/dotnet repository is to have all source code necessary to build the .NET product available in one repository and identified by a single commit.
• The VMR also aims to become the place from which we release and service future versions of .NET to reduce the complexity of the product construction process. This should allow our partners and and 3rd parties to easily build, test and modify .NET using their custom infrastructure as well as make the process available to the community.
• Lastly, we hope to solve other problems that the current multi-repo setup brings:
  • Enable the standard down-/up-stream open-source model.
  • Fulfill requirements of .NET distro builders such as RedHat or Canonical to natively include .NET in their distribution repositories.
  • Simplify scenarios such as client-run testing of bug fixes and improvements. The build should work in an offline environment too for certain platforms.
  • Enable developers to make and test changes spanning multiple repositories.
  • More efficient pipeline for security fixes during the CVE pre-disclosure process.

We will achieve these goals while keeping active coding work in the separate repos where it happens today. For example: ASP.NET features will continue to be developed in dotnet/aspnetcore and CLR features will be continue to be developed in dotnet/runtime. Each of these repos have their own distinct communities and processes, and aggregating development into a true mono-repo would work against that. Hence, the "virtual" monolithic repo: the VMR gives us the simplicity of a mono-repo for building and servicing the product, while active development of components of that product stays in its various existing repos. The day to day experience for typical contributors will not change.

Limitations

This is a work-in-progress. There are considerable limitations to what is possible at the moment. For an extensive list of current limitations, please see Temporary Mechanics.
See the Unified Build roadmap for more details.

Supported platforms

• 8.0
  • source-build configuration on Linux
• 9.0+ (WIP)
  • source-build configuration on Linux
  • non-source-build configuration on Linux, Mac, and Windows

For the latest information about Source-Build support for new .NET versions, please check our GitHub Discussions page for announcements.

Code flow

For the time being, the source code only flows one way - from the development repos into the VMR. More details on this process:

• Source Synchronization Process
• Synchronization Based on Declared Dependencies
• Moving Code and Dependencies between the VMR and Development Repos

We expect the code flow to start working both ways in the .NET 9 timeframe. See the Unified Build roadmap for more details.

Contribution

At this time, the VMR will not accept any changes and is a read-only mirror of the development repositories only. Please, make the changes in the respective development repositories (e.g., dotnet/runtime or dotnet/sdk) and they will get synchronized into the VMR automatically.

Dev instructions

Please note that this repository is a work-in-progress and there are some usability issues connected to this. These can be nuisances such as some checked-in files getting modified by the build itself and similar. For the latest information about Source-Build support, please watch for announcements posted on our GitHub Discussions page.

Prerequisites

The dependencies for building can be found here. In case you don't want to / cannot prepare your environment per the requirements, consider using Docker.

Building

1. Clone the repository

   git clone https://github.com/dotnet/dotnet dotnet-dotnet
   cd dotnet-dotnet

2. Build the .NET SDK

   Choose one of the following build modes:

   • Microsoft based build

     For Unix:

     ./build.sh --clean-while-building

     For Windows:

     .\build.cmd -cleanWhileBuilding

   • Building from source

     # Prep the source to build on your distro.
     # This downloads a .NET SDK and a number of .NET packages needed to build .NET from source.
     ./prep-source-build.sh
     
     # Build the .NET SDK
     ./build.sh -sb --clean-while-building

   The resulting SDK is placed at artifacts/assets/Release/dotnet-sdk-9.0.100-[your-RID].tar.gz (for Unix) or artifacts/assets/Release/dotnet-sdk-9.0.100-[your-RID].zip (for Windows).

3. (Optional) Unpack and install the .NET SDK

   For Unix:

   mkdir -p $HOME/dotnet
   tar zxf artifacts/assets/Release/dotnet-sdk-9.0.100-[your-RID].tar.gz -C $HOME/dotnet
   ln -s $HOME/dotnet/dotnet /usr/bin/dotnet

   For Windows:

   mkdir %userprofile%\dotnet
   tar -xf artifacts/assets/Release/dotnet-sdk-9.0.100-[your RID].zip -C %userprofile%\dotnet
   set "PATH=%userprofile%\dotnet;%PATH%"

   To test your built SDK, run the following:

   dotnet --info

Note

Run ./build.sh --help (for Unix) or .\build.cmd -help (for Windows) to see more information about supported build options.

Building using Docker

You can also build the repository using a Docker image which has the required prerequisites inside. The example below creates a Docker volume named vmr and clones and builds the VMR there.

docker run --rm -it -v vmr:/vmr -w /vmr mcr.microsoft.com/dotnet-buildtools/prereqs:centos-stream8
git clone https://github.com/dotnet/dotnet .

# - Microsoft based build
./build.sh --clean-while-building

# - Building from source
./prep-source-build.sh && ./build.sh -sb --clean-while-building

mkdir -p $HOME/.dotnet
tar -zxf artifacts/assets/Release/dotnet-sdk-9.0.100-centos.8-x64.tar.gz -C $HOME/.dotnet
ln -s $HOME/.dotnet/dotnet /usr/bin/dotnet

Codespaces

You can also utilize GitHub Codespaces where you can find preset containers in this repository.

Building from released sources

You can also build from sources (and not from a context of a git repository), such as the ones you can acquire from a dotnet/dotnet release. In this case, you need to provide additional information which includes the original repository and commit hash the code was built from so that the SDK can provide a better debugging experience (think the Step into.. functionality). Usually, this means the dotnet/dotnet repository together with the commit the release tag is connected to.

In practice, this means that when calling the main build script, you need to provide additional arguments when building outside of a context of a git repository.
Alternatively, you can also provide a manifest file where this information can be read from. This file (release.json) can be found attached with the dotnet/dotnet release.

Synchronizing code into the VMR

Sometimes you want to make a change in a repository and test that change in the VMR. You could of course make the change in the VMR directly (locally, as the VMR is read-only for now) but in case it's already available in your repository, you can synchronize it into the VMR (again locally).

To do this, you can either start a dotnet/dotnet Codespace - you will see instructions right after it starts. Alternatively, you can clone the repository locally and use the vmr-sync.sh or vmr-sync.ps1 script to pull your changes in. Please refer to the documentation in the script for more details.

List of components

The full list of components synchronized into the VMR is here (Components.md).

The repository also contains a JSON manifest listing all components in a machine-readable format.

Filing Issues

This repo does not accept issues as of now. Please file issues to the appropriate development repos. For issues with the VMR itself, please use the source-build repository.

ActionBarSherlock Themes in SlidingMenu

How can I change style of the ActionBar in this example?
I've tired this:

@style/Widget.Styled.ActionBar @style/Widget.Styled.ActionBar @drawable/bg_striped @drawable/bg_striped @drawable/bg_striped_split @drawable/bg_striped_split

but it not see parent from Sherlock.

Missing precompiled 4.4.0 jar?

I am having a problem replacing my 4.2.0 version with the 4.4.0 component version and was hoping to update from here.

Shouldn't the update to 4.4.0 have a new jar file (ActionBarSherlock-4.4.0.zip)?

ActionBarPullToRefresh doesn't build with ActionBarSherlock 4.4.0

I blindly tried adding the ActionBarPullToRefresh.dll to my existing project that uses ActionBarSherlock, and started seeing build errors like the following:

package uk.co.senab.actionbarpulltorefresh.library.PullToRefreshAttacher does not exist uk.co.senab.actionbarpulltorefresh.library.PullToRefreshAttacher.OnRefreshListener

The ActionBarPullToRefresh sample app worked fine, so I was confused. I added a reference to ActionBarSherlock (and then Mono.Android.Support.v4), and then the sample project started having build errors:

package com.actionbarsherlock.widget.ShareActionProvider does not exist com.actionbarsherlock.widget.ShareActionProvider.OnShareTargetSelectedListener
package com.actionbarsherlock.widget.SearchView does not exist com.actionbarsherlock.widget.SearchView.OnSuggestionListener 
etc...

Double-clicking the error opens up one of the generated obj/.../*.java files.

Is ActionBarPullToRefresh not compatible with ActionBarSherlock? Can it be made to be if not?

Facebook example error

If I have installed the facebook application, the authentication with Facebook hangs with the error "login fail please contact the marker of this app and ask them to issue 1732910 to facebook".

If I uninstall the facebook application, the authentications works fine.

[Support4] Wrong namespace in fragment class identifier

File: Support4/Support4/Resources/layout-land/fragment_layout_support.xml

This code crashes the Layout example on tablets:

<fragment class="com.example.android.supportv4.app.FragmentLayoutSupport$TitlesFragment"
            android:id="@+id/titles" android:layout_weight="1"
            android:layout_width="0px" android:layout_height="match_parent" />

Should be:

<fragment class="support4.FragmentLayoutSupport_TitlesFragment"
            android:id="@+id/titles" android:layout_weight="1"
            android:layout_width="0px" android:layout_height="match_parent" />

SlidingFragmentActivity not exposed

Much appreciated binding, and a basic menu using SlidingActivity is possible, but I have been completely unsuccessful getting the SlidingFragmentActivity to resolve. Digging into the binding a bit revealed that the SlidingFragmentActivity class does not seem to be exposed.

Osmdroid binding should be updated to 4.2

4.2 is the latest and it seems to have a lot of issues that the original 3.0.8 doesn't seem to have.

error in ActionBarPullToRefresh

When compile the sample I have this error:

Error CS0234: The type or namespace name 'Void' does not exist in the namespace 'java.lang' (are you missing an assembly reference?) (CS0234) (ActionBarPullToRefreshSample)

I have problems with reference :
using Void = Java.Lang.Void;

AdvancedAppLifecycleDemos / InitializingAppAndServices files have invalid characters in file name.

Please consider renaming the 3 files in the services directory that contain "" in the file name. Windows doesn't allow '<' or '>' in file names. Other than that little speed bump the sample is great and exactly what I was looking for.

Thanks!

line color problem with LinedEditText.cs

here is my code for Line edit text, but I have faced problem with the line color.
line colors are not same, when i drew it in edittext..

                public class LineEditText : EditText
                {
                    private Rect rect;
                    private Paint paint;
    public LineEditText(Context context, IAttributeSet attrs) : base(context, attrs){

        rect = new Rect ();
        paint = new Paint ();
        paint.SetStyle (Android.Graphics.Paint.Style.Stroke);
        paint.Color = Color.LightGray; 

    }


    protected override void OnDraw(Canvas canvas) {

        int height = Height;
        int lHeight = LineHeight;
        // the number of line
        int count = height / lHeight;
        if (LineCount > count) {
            // for long text with scrolling
            count = LineCount;
        }

        // first line
        int baseline = GetLineBounds(0, rect);

        // draw the remaining lines.
        for (int i = 0; i < count; i++) {
            canvas.DrawLine(rect.Left, baseline + 1, rect.Right, baseline + 1, paint);
            // next line
            baseline += LineHeight;
        }
        base.OnDraw(canvas);
    }


    }

AppRestrictSchema Default Value from XML not working.

I just tried running the https://github.com/xamarin/monodroid-samples/tree/master/android5.0/AppRestrictionSchema and I changed the default value of the "can_say_hello" to true in the app_restrictions.xml file but nothing changed. In fact, when I put a breakpoint to check the value of the restrictions bundle, it was empty.

I think the xml file is not being parsed/read correctly (if at all).

I ran this sample on a Nexus 7 (5.0.2)

Facebook Binding Sample "Argument applicationId cannot be null"

I added the facebook binding to my project and attempted to follow the facebook sdk instructions for setting up a session based login activity.

When the Com.Faccebook.UiLifecycleHelper is being initialized, I get an error that says "Argument applicationId cannot be null"

I tried adding:

<meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/app_id" />

to AndroidManifest.xml, and the following to Strings.xml:

<string name="app_id">12471902489108</string>

but the application id still cannot be read.

I tried 10 different capitalizations for "com.facebook.sdk.ApplicationId", but I still get the same error.

Here is the stack trace for the exception:

Share text in facebook, twitter, etc.

I do that

public override bool OnCreateOptionsMenu(IMenu menu)
{
     SupportMenuInflater.Inflate(Resource.Menu.share_action_provider, menu);

    Com.Actionbarsherlock.View.IMenuItem shareMenu = menu.FindItem(Resource.Id.menu_item_share_action_provider_action_bar);
    Com.Actionbarsherlock.Widget.ShareActionProvider shareAction = (Com.Actionbarsherlock.Widget.ShareActionProvider)shareMenu.ActionProvider;
    shareAction.SetShareIntent(createShareIntent());

   return true;
}

when I execute "SetShareIntent", I received a null object.

Anybody can help me.

Google Maps MD5 fingerprint

Hey All,

From information on the internet, you need to request a API key by giving the MD5 fingerprint from your android debug store. All examples state it should look like
keytool -list -alias androiddebugkey -keystore ~/.android/debug.keystore -storepass android -keypass android
however from looking at the way the project gets signed, it uses a different location as shown below
-keystore "obj/Debug/debug.keystore" -storepass "android" -keypass "android"

Running that as so
keytool -list -alias androiddebugkey -keystore "obj/Debug/debug.keystore" -storepass "android" -keypass "android"
produces a different MD5 fingerprint and this ends up working with the Google Maps example, is the ~/.android/debug.keystore not the correct place to do this?

Cheers,

ChrisNTR

all this example to run from the fragment?

// Construct an Intent as normal
            Intent intent = new Intent (this, typeof(DetailActivity));
            intent.PutExtra (DetailActivity.EXTRA_PARAM_ID, item.id);

            ActivityOptions activityOptions = ActivityOptions.MakeSceneTransitionAnimation (
                                                  this,
                // Now we provide a list of Pair items which contain the view we can transition from, and the name of the view it is 
                // transitioning to, in the launched activity
                                                  new Pair (view.FindViewById (Resource.Id.imageview_item), DetailActivity.VIEW_NAME_HEADER_IMAGE),
                                                  new Pair (view.FindViewById (Resource.Id.textview_name), DetailActivity.VIEW_NAME_HEADER_TITLE)
                                              );
            // Now we can start the Activity, providing the activity options as a bundle
            StartActivity (intent, activityOptions.ToBundle ());

I have an error when you run this code inside the Fragment. Apparently as an argument I need main Activity. How can I get it?

Mono.Actionbarsherlock don't work on pre-Honeycomb Android devices

Would you down minimum target to 2.2 or 2.1 (pre-Honeycomb)? I want to use this library for academic application.

Thanks a lot.

MapsAndLocationDemoV2 on screen rotation

UPDATE 04/29/2013: Please check at my latest comment!

When running the MapAndLocationDemoV2 on my Samsung Galaxy S3 device, it works fine until I change the screen orientation. Then, the screen is redraw correctly but the Google Maps fragment is not responding anymore. I can click on the "Zoom In/Out" button but the map won't change. Touching the map does not do anything.

The bug is happening when screen to rotating ONCE the application is running. Starting the application in landscape initialy is working.

I've trap those to lines in the debug log while changing my screen orientation:

01-07 14:19:41.165 E/SpannableStringBuilder(20204): SPAN_EXCLUSIVE_EXCLUSIVE spans cannot have a zero length
01-07 14:19:41.165 E/SpannableStringBuilder(20204): SPAN_EXCLUSIVE_EXCLUSIVE spans cannot have a zero length

ActionBarViewPager sample throws exception when orientation is changed

While running the ActionBarViewPager (HelloSwipeViewWithTabs) sample an exception is thrown when the orientation is changed.

The issue occurs base.OnCreate(bundle); is executed when Activity1 is recreated due to the orientation change:

    {
        protected override void OnCreate(Bundle bundle)
        {
            base.OnCreate(bundle);

            // Set our view from the "main" layout resource
            SetContentView(Resource.Layout.Main);

                var view = i.Inflate(Resource.Layout.tab, v, false);
                var sampleTextView = view.FindViewById<TextView>(Resource.Id.textView1);

            );

            adaptor.AddFragmentView((i, v, b) =>

            );

            pager.Adapter = adaptor;
            pager.SetOnPageChangeListener(new ViewPageListenerForActionBar(ActionBar));

            ActionBar.AddTab(pager.GetViewPageTab(ActionBar, "Tab1"));
            ActionBar.AddTab(pager.GetViewPageTab(ActionBar, "Tab2"));
        }
    }
}

I've based a portion of an app I'm currently developing on this sample and although my app doesn't require landscape orientation, I'd still like to understand why this is throwing and the proper way to avoid it...

Xamarin.Android on Linux

Hi,

I've already using Ubuntu 14.04 LTS Linux system. My question is: is there any option to use Xamarin Android libraries on this Linux operational system?

I know that Xamarin team don't want to make Xamarin IDE for Linux (prove I found here: https://forums.xamarin.com/discussion/1599/xamarin-studio-in-linux), but is it possible to use these Android libraries in Mono Develop? I've already heard about Mono for Android, but according to this page:
https://developer.xamarin.com/releases/android/mono_for_android_4/mono_for_android_4.4/
I see that Monodroid has now version 4.4, where Xamarin.Android has the newest version as 6.0. Is Mono for Android up-to-date or just an old, already deprecated project.

Could you explain me clearly how nowadays does situation with Xamarin.Android for Linux. Monodroid and Xamarin IDE for Linux looks like?

Thanks in advance,
Piotr

LeaderboardsAndAchievementsDemo: doesn't sign out on SignOut()

There is a sign-out button on the LeaderBoards page and if try to sign out by tapping this button the GoogleApiClient doesn't disconnect - it just goes to "signed out" state.

Here is the fix for GameHelper.cs to perform complete sigh out:

        const int RESULT_RECONNECT_REQUIRED = 10001;

        public void OnActivityResult (int requestCode, Result resultCode, Intent data) {
            if (requestCode == RC_RESOLVE) {
                if (resultCode == Result.Ok) {
                    Start ();
                } else {
                    if (OnSignInFailed != null)
                        OnSignInFailed (this, EventArgs.Empty);
                }
            } else if ((int)resultCode == RESULT_RECONNECT_REQUIRED) {
                SignOut (true);
            }
        }

        public void SignOut(bool reconnectingRequired = false) {
            SignedOut = true;
            if (_googleApiClient.IsConnected) {
                if (!reconnectingRequired) {
                    GamesClass.SignOut (_googleApiClient);
                }
                Stop ();
                using (var settings = this._activity.GetSharedPreferences ("googleplayservicessettings", FileCreationMode.Private)) {
                    using (var e = settings.Edit ()) {
                        e.PutString ("playerid", String.Empty);
                        e.Commit ();

JniDemo and JNIDemo should be merged

It seems that JNIDemo and JniDemo were created on case sensitive fs, thus appear as separate folders and versions.

Should be merged.

Set shared checkable behavior across all groups in NavigationView in Cheesesquare

In the Cheesesquare sample only items in the first group is checked in the NavigationView. I want to make items in second group checked too.

something like this:
http://howtobox.org/how-to-set-shared-checkable-behavior-across-all-groups-in-navigationview/

IMenu m = navigationView.Menu;

        for (int i = 0; i <= m.Size () - 1; i++) {
            IMenuItem mi = m.GetItem (i);
            if (!(mi == e.MenuItem))
            {
                mi.SetCheckable (false);
            }
        }

        e.MenuItem.SetCheckable (true);
        e.MenuItem.SetChecked (true);

does this make sense?

Can you add this this too the sample?

v5.0 CheeseSquare won't compile if Packages version == 22.2

Cheesesquare currently has mismatched references

The reference points to beta3 and the Nuget points to beta2.

Also you should probably add a 1G Java heap size to the Android build options; I was getting errors prior to that.

Update facebook.jar used in Facebook sample.

BluetoothChat.BluetoothChatService.cs - clarify MY_UUID

I tried this project and not worked. Then I discovered that the problem was in the wrong UUID. I entered 00001101-0000-1000-8000-00805F9B34FB and then worked. The value I got from bluetoothDevice.getUuids () [0] .getUuid () from the device to which i want to connect. So it seems that for CreateRfcommSocketToServiceRecord should use the UUID of the device and not from the application. If so, please modify the Commentary private static UUID MY_UUID

CalendarDemo

I downloaded, compiled and installed the CalendarDemo on my Android and when I run the program and look at the Events I have in my calendars all the Event Days are off my 1.

One of the Events is Dec 6th 2013 and it shows it as Dec 5th 2013
Another is Jan 28th 2014 and it shows it as Jan 27th 2014.

Looking at the code I have to assume that ".dtstart" is not being read right?

Is this a problem I can fix?
