C# UWP Windows 10 Inter Process Communication with MemoryMappedFiles missing

Question

I'm facing a new problem, that occured while coding my IPC for my app.

Before UWP I was able to use the directive using System.IO.MemoryMappedFiles; sucessfully. Now I can't use using System.IO.MemoryMappedFiles; and I need it.

Is everyone facing the same issue? If yes, how do you solved it?

My app doesn't compile anymore.

I already tried to reimport the System.Core.dll as a reference and with DllImport, neither worked.

Answer 1

Direct inter-process communication is not available in Universal apps.

You can use App Services or LaunchUriForResultsAsync to perform tasks that span multiple apps.

Answer 2

Support for MemoryMappedFiles in uwp was added while back. Although the documentation isn't clear, you can create and share MemoryMappedFiles using the directive using System.IO.MemoryMappedFiles. You have to declare codeGeneration capability to be able to do that.
