In this post I discuss the new single-file .NET run experience, in which you can run a C# file directly, without needing a .csproj project file

#dotnet

Cool, Congrats on the new role👏

Do you know if anyone still full-time on the EF team? Noticeable slowdown in progress this year. #EFCore

Next version of the dotnet runfile supports publishing these .cs files to a native binary (via Native AOT learn.microsoft.com/en-us/dotnet...), no dependencies on the runtime, self-contained.
