So, on page 301, I'm suppose to connect a data source to my web service that I'm going to use to connect to a read-write sharepoint external content type. Sounds easy right?

I cannot a data source to the ASP.NET Web Service project. From the materials I have seen online (google manuals), a data source is not supported directly through asp.net.
Am I missing something here? The Data Sources panel is grayed out. Anyone else running into this?

as i said in the other thread, it sounds like you have built a web service instead of a web service application. that is a website instead of a project

there is also a bug or something that grays out some stuff in VS2010 if u are building a lot of different projects without restarting VS.. happened to me that datasource option was grayed when going from a website to a project, and all it took to fix it was to close solution, restart VS and open the solution again
