WPF app based on this template fails to compile

[AArnott]

The XAML compiler seems to not like the read only source tree.

It seems to still be a problem, even for .NET Core WPF projects added to this repo:

1>------ Rebuild All started: Project: WpfApp1, Configuration: Debug Any CPU ------

It is the presence of this in Directory.Build.props:

Library.Template/src/Directory.Build.props

Line 29 in ea9aac0

<PackageReference Include="Microsoft.SourceLink.GitHub" Version="1.0.0-beta2-19367-01" PrivateAssets="All" />

That, in combination with redirecting the obj directory does it. Remove either one and it builds successfully.

I filed a bug against SourceLink: dotnet/sourcelink#492

Workaround

Add this within a <PropertyGroup> in your WPF project file:

<EmbedUntrackedSources>false</EmbedUntrackedSources>
