I have used vb.net sucessfully with autocad but am unable to start with revit. Using the sample "Hello World", When I click on the dll I get the following error

"System.TypeLoadExtension while creating instance of 'Hello World' in "path"where dll file is stored."Could not load type 'Hello World' from assembly 'Hello World, Version=xxxx, Culture=neutral, PublicKeyToken=null".Please help. Thanks
