I'm very pleased that LINQPad 9 includes some support for .NET 10 file-based apps. However, perhaps a fundamental ecosystem difference, that the SDK types that can be specified via #:sdk are not recognized.

To bridge the gap between LINQPad scripts and file-based apps, and to enhance compatibility with various SDK types in the future, I'd like to see an option to explicitly select the major SDKs (Web, Worker, Standard, etc.) that are currently available in the LINQPad script properties, along with support for the #:sdk syntax.
