EnablePreviewFeatures does not work depending on working directory location when performing 'dotnet run'

[ThomasMader]

Describe the bug

Running the test project using dotnet run --project <someAbsolutePath>\ConsoleApp1\ConsoleApp1\ConsoleApp1.csproj works if the current working directory is <someAbsolutePath>\ConsoleApp1 but if it is <someAbsolutePath> the EnablePreviewFeatures setting is somehow not recognized because it leads to the following error.

error CS8703: The modifier 'abstract' is not valid for this ite m in C# 10.0. Please use language version '11.0' or greater.

To Reproduce

Use the description of the bugs with the attached ConsoleApp1 solution.

Is the application you're running targeting net7.0? EnablePreviewFeatures only works on the latest TFM for the SDK being used and it's possible that changing the working directory changes which SDK ends up getting used (because of a global.json or other reason).

Is there an issue with the uploaded solution for you? Otherwise all your questions are answered by that solution. To me it looks like it should not matter which SDK is used, in the end it should compile nevertheless.

I compiled successfully by adding lines 11.0 and CA2252 in ConsoleApp1.csproj file
