ASP.NET 2.0 application won't compile when adding a Microsoft Report to the solution

Question

I have a ASP.NET 2.0 web application. To that solution I add a Report (Reporting Services). I make no further changes to that report. When I try build the application the build fails with the following error originating from that report file :

A namespace does not directly contain members such as fields or methods

Answer 1

The problem was Visual Studio. I've restarted the IDE and could compile the application without problems.
