I’m trying to create .NET 6.0 WinForms application with CMake. I use the `WIN32_EXECUTABLE` property to hide a console during execution, but it doesn’t work and I have to change `Output Type` from `Exe` to `WinExe` manually from Visual Studio or directly in .csproj. Using `VS_GLOBAL_OutputType "WinExe"` has no effect, but in this case CMake inserts `OutputType` into .csproj twice with different values.

Seems like a hole in the C# support to me. Could you please search for and file [a new issue](https://gitlab.kitware.com/cmake/cmake/-/issues) if one doesn’t already exist?
