If I upgrade to 2.1 I get the following error when trying to run my project in the latest VS.
System.IO.FileNotFoundException: Could not load file or assembly 'Telerik.DataSource, Version=18.104.22.168, Culture=neutral, PublicKeyToken=20b4b0547069c4f8'. The system cannot find the file specified.
Downgrading back to 2.0 makes this go away.
Maybe I am missing an upgrade step?
