Should we change these warnings -> errors for the tracking PR?

[vargaz]

Does this still happen ?

It still happens when System.Runtime.Loader gets enabled.

[vargaz]

How can I reproduce this ?

[ilonatommy]

Please, comment out:

runtime/src/libraries/tests.proj

Line 406 in 8c2ef7f

<ProjectExclusions Include="$(MSBuildThisFileDirectory)System.Runtime.Loader\tests\System.Runtime.Loader.Tests.csproj" />

then run:

dotnet build -bl /t:Test src/libraries/System.Runtime.Loader/tests /p:Configuration=Release /p:RunAOTCompilation=true  /p:TargetOS=Browser

example of errors you should get:

Failed to load method 0x6000091 from '/workspaces/runtime/artifacts/bin/System.Runtime.Loader.Tests/Release/net7.0/browser-wasm/publish/Newtonsoft.Json.dll' due to Could not resolve type with token 0100002f from typeref (expected class 'System.Collections.ObjectModel.Collection`1' in assembly 'netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51') assembly:netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51 type:System.Collections.ObjectModel.Collection`1 member:(null). [/workspaces/runtime/src/libraries/System.Runtime.Loader/tests/System.Runtime.Loader.Tests.csproj]

[vargaz]

Why does tests.proj need to be changed ?

[vargaz]

Also, shouldn't it be built using ./dotnet.sh ?

[ilonatommy]

You're right, I've mistaken arguments. RunAOTCompilation != TestNativeAot. No commenting out needed to see the error. Dotnet.sh will have the same effect, you can use it as well.

Can't reproduce this with 908f440.
