.net framework style project support broken?

[theoractice]

Actual behavior

In .net framework style project, PInvoke functions are generated correctly, however the project cannot compile. I have uploaded a repro below.
Error info:

error CS0246: The type or namespace name 'Windows' could not be found (are you missing a using directive or an assembly reference?)

Expected behavior

Project should compile successfully.

Repro steps

Just create a WPF (.net framework) project In latest VS2022 and add some PInvoke functions.

1. NativeMethods.txt content:

SetProcessWorkingSetSize (can be anything)

2. NativeMethods.json content (if present):

3. Any of your own code that should be shared?
   WpfApp1.zip

Context

• CsWin32 version: v0.3.269
• Win32Metadata version (if explicitly set by project): not set
• Target Framework: .net framework 4.8
• LangVersion (if explicitly set by project): latest
