Hi @doaamostafa.eng.e.st, thanks for using our SDK.

Can you please provide a screenshot of the point in the sample application at which you are getting stuck?

Thanks!

Hey @doaamostafa.eng.e.st,

The documentation for the C# wrapper is currently being updated and those instructions are out of date. Instead, can you re-download the C# wrapper from the Zoom Marketplace, open the csproj folder, change to Release and x86 then run it again? No need to move files over from the C++ SDK.

Thanks!  
Michael
