I've got this warning that I can't seem to suppress. It is not a compile time warning because I don't see it in the output window at all nor do I see it on the build machine. However, I don't want developers on my team to be staring at this forever (or until we actually fix the issue). It appears to be a Visual Studio specific warning. I didn't even know those existed.
Warning Info
Description: This project references an earlier version of SQL Server Compact that has no designer support in this version of Visual Studio. To continue without designer support, download SQL Server Compact 3.5 from the Microsoft Download Center (http://go.microsoft.com/fwlink/?LinkId=229598). To upgrade your assets to SQL Server Compact 4.0 and enable designer support, open the project and use the Add Connection dialog box to create a connection to the database.

Please no one answer "upgrade to SQL Server Compact 4.0". I know I can do that but that's not something I can do right now.
Exclude the sdf file from the project
