Nuget Package Updates Not Working

[chocvanstraw]

I just created an MSTest project targeting .net 9. When I go to the Nuget package manager it says I have 4 updates for the following packages:

Microsoft.NET.Test.Sdk 17.11.1 -> 17.12.0
MSTest.Analyzers 3.6.1 -> 3.6.3
MSTest.TestAdapter 3.6.1 -> 3.6.3
MSTest.TestFramework 3.6.1 -> 3.6.3

If I update all of the packages they seem to update fine (the versions change in the project that was updated). However, if I rebuild the solution, the 4 packages listed above all revert back to the previous version. If I go to the nuget package manager, it shows 4 updates again.

Before update:

After update:

After building the solution:

@chocvanstraw Thanks for reporting this. Are you using MSTest.Sdk?

If you're using MSTest.Sdk, please have a look at the limitations documented in https://github.com/dotnet/docs/blob/087483735e3284d6e4f7d078b7fe66ae57218b8c/docs/core/testing/unit-testing-mstest-sdk.md#known-limitations (the known limitations section will isn't yet published to https://learn.microsoft.com/dotnet/core/testing/unit-testing-mstest-sdk, but hopefully it will be soon).
