My new project demands the implementation OpenAuth. Following is my code.
The line
scopes.Add(CalendarService.Scopes.Calendar.GetStringValue())
in the GetAuthorization gives the following error.
Overload resolution failed because no accessible...
GetStringValue is the most specific for these argument. I can understand that GetStringValue is not the method/argument found in the calendarservice.scopes.calendar but my question is why so? I have downloaded this code from some website and most website is giving example in C# but there are hardly any site that is showing any example in VB.Net. Can anyone help me here.
Regards
P.S. I am using Visual Studio 2008.
