I am newbie on VS-2010 Add-Ins so I started with this walkthrough:
But when I am building my Project I get the following error:
'EnvDTE80.Window2' does not contain a definition for 'CreateToolWindow2' and no extension method 'CreateToolWindow2' accepting a first argument of type 'EnvDTE80.Window2' could be found (are you missing a using directive or an assembly)
I have added the assembly reference in my Project (actually the Add-In wizard did). Any suggestions?
