Not able to use c# code library in vb window legacy

Hi @Aditya10989 ,

I believe the error is similar to the VisualBasicValue’1’ requires compilation in order to run, which often is encountered with Vb projects when converted from Windows-Legacy to Windows.

Check the below post on the fix that is recorded already.

Let us know in some more detail maybe with screenshots if possible, which activity produces the error.
