Studio 2020.10.0-beta.149 Community License - The C# Language is not Supported Error Message

[JoeG (Joe Gannuscio)]

After getting the 2020.10.0-beta.149 update I am unable to load or create projects using C# as the language. When I try to create a new project I no longer have the option to select vb or C# and if I try to open an existing C# project I get the following error message: “The C# Language is not supported on your instance of Studio.”

I’m not sure if C# is no longer available for community license or if there is something else going on. Any help would be much appreciated.

Stack Trace:
Cannot open item: UiPath.Studio.Contracts.RecoverableException: The C# Language is not supported on your instance of Studio. —> System.NotSupportedException: The C# Language is not supported on your instance of Studio.

Hi @JoeG

Please see my post here:

UiPath Community 20.10 Preview Release

Hi @ali.belcaid1 Welcome to our UiPath Forum! Please make sure that: you are licensed with a Studio Pro license in Orchestrator (if you are not licensed locally) you switched to Studio Pro in the Studio profile settings After a restart it should work

It will surely solve this issue
