What’s cswinrt.exe (C#/WinRT v2.2.0.241111.1)? Is it safe or a virus?

The `cswinrt.exe` tool by Microsoft Corporation is part of the C#/WinRT project and serves as a bridge between Windows Runtime (WinRT) APIs and .NET applications. It enables developers to access and consume WinRT APIs in C# by generating interop code and projections, facilitating seamless integration between the Windows platform and .NET. Specifically, version "v2.2.0.241111.1" of the tool is designed to work with the Windows SDK, simplifying development for UWP (Universal Windows Platform), WinUI, and other Windows environments. By automating the generation of projections, it eliminates the need for manually writing interop layers, improving developer productivity and compatibility.

Below are 4 simple steps you can take to see if the cswinrt.exe process is safe or malware.

  1. Scan the executable with Microsoft's built-in tech
  2. Find cswinrt.exe's publisher
  3. Search the executable's hash with VirusTotal
  4. Monitor the executable's behavior

What does it mean if someone is the publisher of a PC .exe (executable or process)?

The publisher of an executable is the entity responsible for its distribution and authenticity. Most processes/executables on your PC should be signed. The signature on the executable should have been verified through a third party whose job it is to make sure the entity is who it says it is. Find an unsigned executable? You should consider scanning any completely unsigned .exe on your PC.
