Quality Assurance - Csharp Coding Guidelines link does not work

I have observed that in dotnet-developer-projects.md under Quality Assurance section link for C# Coding Guidelines is broken. It says that page does not exist.

.NET 4.6.1 GC taking a lot of longer time than 4.5

Hi .NET Team,

I found .NET 4.6.1 is still not fix the bug of GC taking a lot of longer time than 4.5 on Windows Server 2008 R2 SP1, but there is no hotfix like as KB3088957 for .NET 4.6, so how can I do? thank you very much.

Projects should probably be alpha-order

The projects in this list should probably be alpha-order. It's a best way to avoid bias and also help people know where additions should go.

Problem running dotnet on Ubuntu 14.04

I followed the installation instructions at https://www.microsoft.com/net/core#ubuntu.

Facing the following issue:

dotnet new

Erroroneous/empty git repo?

Hi,

I've just tried:

git clone [email protected]:Microsoft/dotnet.git /tmp/dotnet
find /tmp/dotnet/ -path /tmp/dotnet/.git -prune -o -type f | rev | cut -d . -f1 | rev | sort | uniq -ic | sort -rn

Grepping for something related to the project, but it does not show anything helpful (except for 4 md files, 1 license and git files).

Is this repo correct?

[Proposal] To establish a official IRC for discussions and collaborations

Pardon, writing here because could not find a better place, if there's one please include in docs for .net f/w

Including native libraries in dotnet projects

I have a legacy project that has a published a nuget package that looks like this:

Those are c++ dlls under the runtime folders, and it is not a dotnet/project.json project.

When I include this project as a dependency, I see these c++ dlls are included in the output dir when I perform a dotnet publish. however, they are not included in the output dir when I perform a dotnet build. This means that when I try to run my project in Visual Studio, it cannot find the required c++ libs, because they are not in the bin directory.

I have played around with copyToOutput includes and cannot seem to get these dlls to appear in output. Is there something broken or is this behaving as expected?

LambdaCompiler

I found the Microsoft LambdaCompiler used e.g. by Moq is much slower in 64bit compared to 32bit even with .net 4.6 RyuJit. Where do I address this issue?

Unexpected character encountered while parsing value: #

I'm getting the following error when setting up a new Windows 7 64-bit box (VS 2015 Preview 3, .Net 1.0.0-preview3-003612)

Add commercial projects list

Create a commercial projects list to provide a showcase opportunity for those projects.

Might be a good idea to call out/list the OSS projects that the commercial projects take advantage of/are built on. This would further showcase the OSS projects (including non .net ones).

Is it possible for UWP to refer a .NET Core console/library project?

Add python support to VS. I don't want other crappy IDEs handling my python code anymore make a python IDE part of VS

Like what I said above all the IDEs I find are slow to load for me the VS ones load faster than Photoshop CS6. So, I need such IDE that is great, knows what to highlight, and also knows other languages as well. and is better than Notepad++. As well as a way to debug python code in it and ways that is suggests on making it better as well as a simple way of python 2.x to 3.x conversion without less of functionality. Sadly I have some python 2 code that uses some bytes things that python 3 does not let me use.

Review "readonly" usage

According to https://github.com/Microsoft/dotnet/blob/master/CONTRIBUTING.md "readolny" should be used when possible and I think it isn't for example in System.Numerics Matrix3x2

.NET 4.6.2 with Windows 8

¿Is there a reason why Windows 8 has been discarded from the Supported Operating System list of .NET 4.6.2? I have installed the update successfully in a Windows 8 Enterprise 64bits.

dotnet command in Docker container does not return

I tried to run dotnet restore, dotnet run and dotnet new in a Ubuntu container using the published microsoft/dotnet image. The commands run successfully but do not return; the command line hangs and I have to exit and re-enter the container. When I re-enter, I can see the files have been created successfully.

Discovery for new .NET Team projects

I see that CLRMD was published. That's great. How are people supposed to find projects like that, particularly when they are in the Microsoft not dotnet orgs.

Three potential options:

• Add them to: https://github.com/Microsoft/dotnet/blob/master/dotnet-developer-projects.md
• Add them to a new file, to avoid being lost in the noise: dotnet-team-projects.md
• Add them to both

Thoughts?

Command Line generated projects into Visual Studio

Hi, I followed the tips on this web link:
http://dotnet.github.io/getting-started/
Both the Windows and Docker samples run successfully, my question is: how to convert the command line generated projects(with project.json and nuget files) into Visual Studio so that I could use this powerful IDE? When I created the DNX project in Visual Studio and copied the src folder into DOCKER, and run the dotnet restore/run, it generated errors:

CNG key providers to Mage and Mageui SDK tools fails on XBAP compile

In v4.6.2 Framework under the Windows Forms changes, the following change is not working

• Added support for CNG key providers to Mage and Mageui SDK tools [194373]

When compiling a WPF Solution as an XBAP application where the Project file contains a PropertyGroup with the HostInBrowser value set to True and using an RSA SHA2 CNG Certificate for Code Signing, the compilation fails the SignFile Task with error MSB3482.

This is the same error message that would be put out from the mage.exe utility prior to including support for the CNG Certificates.

Program with enabled RyuJit and enabled tail cals optimization produces incorrect result

We have a simple program

[<EntryPoint>]
let main argv = 
    let zero = bigint(0)
    let one = bigint(1)
    let rec ack (m:bigint) (n:bigint) cnt =
            if m = zero then cnt(n + one)
            elif n = zero then ack (m-one) one cnt
            else (ack m (n-one) (fun x -> ack (m-one) x cnt))

    ack (bigint(3)) (bigint(1))  id |> printfn "%A"
    0 // return an integer exit code

Compile it as
fsc.exe Program.fs --tailcalls+
This code works correct only when we run it with <useLegacyJit enabled="1" />.

Expected behavior(with <useLegacyJit enabled="1" />)

Output:13

Actual behavior(without <useLegacyJit enabled="1" />)

Output:1

Good idea?

Ask Dot can not be recognized by razor and requires a brackets

if I use:
@object?.ToString()
in razor, it will be an error

The fully qualified file name must be less than 260 characters, and the directory name must be less than 248

I have moved my project folder to C:\V7 a short one, I keep getting the error below when trying to publish my web app to Azure web app. Can the message below at least show whitch file has long file name?

How to solve this issue?

Memory Mapped File access : the file is being used by another process

I am trying to use MemoryMappedFile to write some bulk data from the database. Whenever I am running application in a single instance,it works perfectly well-as the writing is taking place sequentially. But whenever I am trying to run the same application in multi-instance mode,it is failing to write to the file. If one instance is writing data to the file,the other instance which got instantiated in parallel is unable to access this file.

I looked at the file.cs class in the framework but I could not find a property or method which can give me information if the file is free to be written i.e.,it is not being used by any other process.

Could someone help me -how do I check if the file is not being used by any other process?

public static void WriteToMMF(string fileName, byte[] records, long? beginOffset, long? endOffset)
{
//create MMF
try
{
using (var writeMMF = MemoryMappedFile.CreateFromFile(fileName, FileMode.OpenOrCreate, "OutboundMMF", endOffset.Value))
{
using (MemoryMappedViewAccessor accessor = writeMMF.CreateViewAccessor())
{
accessor.WriteArray(beginOffset.Value, records, 0, records.Length);

                }
            }
        }
        catch (Exception ex)
        {

        }
    }

Progressive JPEG

Hi,

the question comes up every now and then: will System.Graphics.Bitmap somewhen be able to save progressive JPEGs? Which github repository is the home of System.Graphics?

Which CLA?

Which CLA needs to be signed to contribute to .NET? Would be good to have this information in CONTRIBUTING.md.

2 dotnet run command cannot work on ubuntu 14.04

First of all sorry my bad English.

My question is.. I cannot 2 dotnet run command on ubuntu. Please help me. I have a web project, running on ubuntu works perfect but now i added web api project but i cannot start 2 project at once.

Web api project program.cs file:

namespace KatmanWebAPI
{
    public class Program
    {
        public static void Main(string[] args)
        {
            var host = new WebHostBuilder()
                .UseKestrel()
                .UseContentRoot(Directory.GetCurrentDirectory())
                .UseIISIntegration()
                .UseStartup<Startup>()
                .UseUrls("http://localhost:5021")
                .Build();

            host.Run();
        }
    }
}

And then webui project Program.cs file:

namespace KatmanWebUI
{
    public class Program
    {
        public static void Main(string[] args)
        {
            var host = new WebHostBuilder()
                .UseKestrel()
                .UseContentRoot(Directory.GetCurrentDirectory())
                .UseIISIntegration()
                .UseStartup<Startup>()
                .UseUrls("http://localhost:5020")
                .Build();

            host.Run();
        }
    }
}

I enter in KatmanWebUI project folder and run dotnet run command works properly and going fine. Also i run this server 70 days without restart. But when runs KatmanWebUI project and then i am starting KatmanWebAPI project and then interfering each other. For example when starting a page from KatmanWebUI page and css is going down. Or some icons not showing and web site in not going properly.

My nginx file about server backend:

upstream backend {
        server 127.0.0.1:5020;
        server 127.0.0.1:5021;
        server 127.0.0.1:19920;
}

So how can i start 2 projects run properly. System is Ubuntu 14.04 LTS Trusty.

Wrong Currency in CultureInfo("lt-lt")

Lithuania switched to EURO (from Litas) since January 1st.
With .Net 4.6 when culture info is Lithuanian (lt-lt) it still gives Litas as currency.

Is there are any workarounds for that?

P.S. I assume this is the same for Latvia too. (they joined EURO too)

Different formats of dotnet461-api-changes.md and dotnet46-api-changes.md

releases/net461/dotnet461-api-changes.md is a markdown with fenced code block of diff format. It looks very nicely.
But releases/net46/dotnet46-api-changes.md is just an html despite its extension.
It would be nice to see the same format in both files.

p.s. also let me ask how do you generate such diff for api changes?

Consider changing / clarify PR wording in contributing.md

Was looking at contributing.md. Under "creating a PR", I saw two issues I wanted to discuss:

1. Why is it important that the PR be created in a branch, as opposed to their master? Is it so that their master is clean if the PR is rejected?
2. We probably want to use a pronoun other than "our", for point 5, but use something more general that doesn't connote ownership.

The Microsoft .NET Framework Assistant Firefox extension by Microsoft is the only connection between Firefox and the Common Language Runtime for .NET in order to run ClickOnce WebLaunchers from Firefox. Is the code for that also in this repository? Who controls the Microsoft account?

It works nicely, but in at least Firefox 30 through 36, There is no mention of .NET or CLR in the userAgent (anymore), and there is no application/x-ms-aplication mentioned in navigator.mimeTypes.

We would like to be able to detect the presence/availability of this ClickOnce extension, so we can switch in javascript between opening the plugin page or opening the WebLauncher. It could use an update to show itself to client side javascript, or maybe there's a secret someone forgot to tell me.

Failed to restore packages on Docker Build

I'm getting an error on a new web project (and a few others) with restoring packages. Not machine specific.

Is Castle Project a "Platform"?

Castle Project is listed as a "Platform". That doesn't seem right. How should it be listed?

Propose Adding Akka.NET to Developer Projects List

Akka.NET is an implementation of the Actor Model for the .NET Framework, enabling some really powerful distributed systems scenarios (self-healing systems, painless handling of concurrency / state, etc.) -- this description does not quite do it justice.

I'm not certain which category it belongs in -- hence why this is an issue instead of a PR. Perhaps @Aaronontheweb, @rogeralsing, or @skotzko could weigh in on that. But it's a valuable project adding an additional dimension to the .NET ecosystem and I think it's a great fit for this list.

Definition of Platforms category

I personally feel there's a big difference between "platform" projects delivering a platform inside applications (like MVVM projects), and projects like .NET Core and Mono, which deliver a .NET platform. Maybe that distinction makes sense for the project list?

Stop adding auto connection strings in config files

Somewhere 2 versions ago .NET started adding invisible automatic connection strings to application configuration files. Trying to retrieve the 0th Connection String would always return:

"data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true"

Removing this behavior means a trip to the machine.config file for each installed .NET framework and removing this value from there.

Can we please have a patch that removes this behavior?

Will Microsoft HTTP Client Libraries be added to GitHub?

Do you planing make wiki documentation on GitHUB?

Hello,

What you think about documentation on GitHUB or example usages?

Now I can not search WIA or TWAIN example on .NET in Internet? How about write in Wiki with smaple code ready to compile?

Thanx.

SqlDataReader.NextResultAsync and ReadAsync cause unobserved task exception even when awaited

I posted a fairly critical bug in the .NET Framework to Connect. I've heard nothing in reply for four months. 4.6.2 has come and gone. Is Connect a dead end? I would appreciate it if someone would respond.

Marshalling a returned struct with a boolean field crashes

This code:
using System.Runtime.InteropServices;

namespace TestMarshal
{
    public struct QVariant
    {
        [StructLayout(LayoutKind.Explicit, Size = 16)]
        public struct Internal
        {
            [FieldOffset(0), MarshalAs(UnmanagedType.I1)]
            public bool d;
        }

        [UnmanagedFunctionPointerAttribute(CallingConvention.ThisCall)]
        public delegate Internal _Interpolated_0Delegate(System.IntPtr instance);

        public static _Interpolated_0Delegate _Interpolated_0DelegateInstance;

        public static Internal _Interpolated_0DelegateHook(System.IntPtr instance)
        {
            return new Internal();
        }
    }

    class Program
    {
        static void Main()
        {
            QVariant._Interpolated_0DelegateInstance += QVariant._Interpolated_0DelegateHook;
            var functionPointerForDelegate = Marshal.GetFunctionPointerForDelegate(QVariant._Interpolated_0DelegateInstance);
            functionPointerForDelegate.GetHashCode();
        }
    }
}

crashes with:

"Method's type signature is not PInvoke compatible."

It crashes the same way if MarshalAs(UnmanagedType.I1) is added to the field.

I have tested this with .NET 4.0 and .NET 4.5.1, no difference in behaviour.
It works properly on Mono with or without a MarshalAs attribute.
