Well, this might be a shot in the dark but, are you sure you are trying to use the "context." variable inside of a method body? There is absolutely no reason for VS not to be able to find the properties and method declarations of a given class otherwise.
If this is not the case, I will need some more information on this one.
Can you please check if OpenAccess has successfully generated the correct OpenAccess Context class and method definitions for the stored procedure. You can do that if you expand the .rlinq file and look into the .vb file with the same name. If you don't see the arrow that should expand the .rlinq file, try selecting the "Show All Files" option in the Solution Explorer. It's in the toolbar on top of the Solution Explorer.
Do not hesitate to contact us if you have any further troubles.
All the best,
the Telerik team
