jaredpar · 2024-05-10T16:21:42Z

This adds the .NET 9 reference assemblies into our test harness.

1.7.2

Would it make sense to abstract this version number so that we can upgrade from just one location? #Closed

Yeah that would make sense now that I've unified them all.

Consider adding a test or upgrading an existing one to exercise this new TFM #Closed

All the places for the new tests are in the ref generic interfaces branch. For merge purposes it's better to have the initial commit here. Once Aleksey merges this in we'll move to this TFM. If there are any issues I will deal with the fallout.

Done with review pass (iteration 3)

LGTM Thanks (iteration 4)

Why are tests failling if this isn't used anywhere?

Example test failure in Microsoft.CodeAnalysis.CSharp.UnitTests.CollectionExpressionTests.SpanArgument_01(targetFramework: Net80):

++> IL_001d: newobj "System.ReadOnlySpan<int?>..ctor(ref readonly int?)" --> IL_001d: newobj "System.ReadOnlySpan<int?>..ctor(in int?)"

Hmm ... that is odd.

The tests all pass when run individually but fail when the entire test class is executed. We must be holding onto state somewhere

I do not see a single line in CollectionExpressionTests that starts with IL_001d: newobj. What am I missing?

Regarding the diff, is it possible that we are updated to ref assembly for 8.0 that use ref readonly in the constructor?

@jaredpar

The tests all pass when run individually but fail when the entire test class is executed. We must be holding onto state somewhere

It is likely that CI failures are expected given the changes to ref assemblies that you are making. It looks to me like your branch is behind main enough to make the difference between the local state and the merged state the CI is running against. That is why CI failures do not make sense in context of your local branch. Consider merging main into you branch, then running tests locally.

Figured out what is happening here. When I updated the reference assemblies recently I missed updating the net80 set. That means the NuPkg remained at 1.4.5 which is based off of the 8.0.0-preview.7.23375.6 version of .NET. The ref readonly parameter changes came in after that. Now that I unified the versions into a single MSBuild prop that dragged the net80 version forward to RTM and we're seeing the signature differences.

alrz · 2024-05-11T07:56:59Z

Kind of tangential, but how to avoid building the project for every TFM when building locally? Is there a quick way to limit tests/build to only one framework by default?

@jaredpar I think we should change this to net9.0. Otherwise test scenarios using TargetFramework.Net90 won't execute. #Closed

@AlekseyTs

This. Moving to a new net9.0 inside our project files is a fairly big change. I wanted to separate out making the new reference assemblies available and moving to the new TFM.
