Hello,
I’m having an issue when compiling a library with UiPath Studio 2020.6
System.AggregateException: One or more errors occurred. —> UiPath.ActivityCompiler.Exceptions.UiPathLocalizedException: Unable to create activity builder for document. Reason was 'Cannot create unknown type ‘{http://schemas.microsoft.com/netfx/2009/xaml/activities}Catch({http://schemas.microsoft.com/netfx/2009/xaml/servicemodel}CommunicationException)’
when I compile with mi old Studio 2019.6, it compiles perfectly.
Maybe a dependence is lost with the new installation or similar. The Studio doesn’t shows any error until compilation. Thank you in advance.
