I got this error when I use Visual Studio 2010 to program some SharePoint 2010 stuff. It is a simple console program. This exception happens at the following line:
SPWebApplication webApplication = SPWebApplication.Lookup(new Uri("http://mysiteurl"));
Below is another error:
The Web application at http://mysiteurl could not be found. Verify that you have typed the URL correctly. If the URL should be serving existing content, the system administrator may need to add a new request URL mapping to the intended application.
and this happens at line
SPSite site = new SPSite("http://mysiteurl");
Both of the errors have the same root cause.
Solution:
Right Click your project, Choose Properties. Go to tab “Build”, Change Platform Target from “x86” to “Any CPU”. Recompile your project and you will be all set to go.
