launch dotnet run app.cs from docker sdk image

[tomap]

Describe the bug

Hello,

I'm trying to launch the new file-based dotnet run (docker sdk 10.0)

But this does not work

Which .NET image(s) are you using?

mcr.microsoft.com/dotnet/sdk:10.0

Steps to reproduce

dotnet run -v:diag changelog.cs

result:

I think I found the issue.
There was a .sln (and some .props files) in the parent directory of my script, and I believe this was breaking the script

I ran a rm . in the parent directory before doing dotnet run, and it fixed the issue

Thanks for following up. I can also confirm that the file-based app support appears to be working in the .NET 10 SDK image. Executing code from stdin also works.

Interestingly enough I discovered dotnet/sdk#51282 when trying to reproduce this. But seeing as that only happens in that specific scenario (from the filesystem root), I think we can close this.
