Are you using UiPath 2019.10.3 version ?

If yes then it seems like some bug in it.

I am using 2020.10.2 Enterprise edition

The Exact error :
Unexpected error has occurred during the library compilation process:
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/winfx/2006/xaml/presentation}Point’.’. —> System.Xaml.XamlObjectWriterException: Cannot create unknown type '{http://schemas.microsoft.com/winfx/2006/xaml/presentation}

@SrenivasanKanna

Create new project using Library process and just copy all old workflow files to it. And then check it once.

I have the same issue.
I got this output message when running my process:
Unexpected error has occurred during the library compilation process:

Unable to create activity builder for Devoir1.2\Main.xaml. Reason was ‘Cannot create unknown type ‘{clr-namespace:UiPath.Excel.Activities.Business;assembly=UiPath.Excel.Activities}ExcelProcessScopeX’.’.

Does anyone resolved ?

Thanks for helping,

I had the same error message trying to publish a library project and found the cause / solution.

I had used the word “System” as a variable name, which is also the name of a .net class or namespace, and this was causing the issue when trying to Publish. It seemed to think in my project that I was referring to the class “System” without specifying which method to use… I renamed my variable to “option_System” and everywhere in the project - and then this fixed it for me.

Try checking that you don’t have any named variables/arguments that could be causing problems (avoid using any of the words listed in your Imports tab)
