Renaming the default branch to main.

On 17th March 2021 we're going to rename the default branch in this repository to main. For more details, see our earlier announcement.

Exceptions thrown when running demos in Debug mode

An exception is thrown whenever I click any of the first three links in the browser window (see below). I am running Visual Studio 2017 express on Windows 10.

System.Windows.Data Errors

I see a lot of these in the console when running AssessingPeoplesSkills project (see below), but not sure if it is actually affecting anything... the program seems to run fine.

Running with Visual 2019 on the Mac with M1 chip

Hi,

I read that your framework only runs on Windows machine? After downloading Mono, I get 149 errors when building Samples in (main). The first error is "Could not resolve this reference. Could not locate the assembly “PresentationCore”"

Does your framework run on any machine other than a Windows machine? Thanks.

Cannot build sample code on mac with .NET v2.1.814

Not sure if anyone recently has tried to install the app on Mac. Following the instruction mbmlbook/BUILDING.md and I've ran the build command below

dotnet build -f netcoreapp2.1

It errors out, pasted the error message down there. I am very new to C# and have zero clue on how to fix this. Posted it here and could need some on it.

/usr/local/share/dotnet/sdk/2.1.814/Sdks/Microsoft.NET.Sdk/targets/Microsoft.PackageDependencyResolution.targets(198,5):
error NETSDK1005: Assets file '/Users/gchu/Code/mbmlbook/src/MBMLCommon/obj/project.assets.json' doesn't have a target
for '.NETCoreApp,Version=v2.1'. Ensure that restore has run and that you have included 'netcoreapp2.1' in the TargetFrameworks
for your project.

Minor: missing link from end of Chapter 6 to Chapter 7

Harnessing the Crowd Chapter Data

Hi,

The book is excellent and I love the explanations. How can I get a copy of this dataset?

I checked this link as well and the link to the data seems broken.

Any suggestions?

Samples targeting for .NET Core 3.0

Hi, Microsoft announced general availability of .NET Core 3 on September and described it as the future of .NET and Visual Studio 2019 being the newest version of the IDE. Will these source code samples be upgraded to target the latest version before the book is released?

It would be a shame if the code samples are broken on the new version of .NET since it has succeeded 2.1

Thanks

UI makes examples harder to understand.

Love the book, and the repo, but the examples have too much UI code especially for the basic examples. It takes focus away from actually learning how the varibles, properties, and engine work together because you have to slough through UI code and mentally parse whats there for machine learning and what is there for UI purposes.
