While reviewing the release notes for 5.4.54524.1229, the following stands out:

“When publishing your app, please copy the Microsoft runtime libs to bin and bin/aomhost directories.”

Is this requirement still valid for recent SDKs?

It’s an unusual request, as the runtime DLLs are managed by Windows (Win10 comes with universal C runtime), and if I examine my app using a dependency checker, I don’t find any missing dependencies. Can you clarify why this is needed?

Thanks,

Bill Gardner

Hey @ministudio,

Thanks for using the dev forum!

This is to prevent an issue when screensharing that only occurs on certain windows machines. If you can successfully screenshare without moving the DLL’s, you shouldnt need to do this.

Thanks!

Thanks for the clarification, I don’t need to worry about this.
