Hello

I can run the v3 sample code for chapter 4, but not v1 or v2
Error given as below

"Could not load file or assembly 'Microsoft.VisualBasic, Version=2.0.0.1, Culture=neutral, PublicKeyToken=6315780d5082271f' or one of its dependencies. The system cannot find the file specified."

I notice that the config file information for v1 and v2 makes reference to a PublicKeyToken, this is not required in the v3 config file which works, can you please help?

Thanks
Gary
