I have a project built on the basis of Net Framework 4.7.1 in Visual Studio and I need to transfer it to Unity, the project is written in C# however, when transferring, an error occurs that Unity does not see the Windows.Gaming library.Input I added it to Plugins in Assets, but still there is no result, how to make Unity finally see this library, or perhaps there is a specialized site where there is this library sharpened for this engine
I would recommend going to the original Visual Studios project and stubbing all input out to a single class that contains the input values, such as move, mouse, clicks, fire, thrust, etc.
Then bring it over to Unity and use Unity to gather input and stuff it into that class before your main code runs.
Anything else is going to be a loooooooooooong uphill slog against Microsoft and everything in C# that is far ahead of where Unity is in C# / .NET land.
