DLL is not supporting in windows 7 phone application using visual studio 2010

If I add any dll (like sqllite3.dll, sqlliteclient.dll) I get the below message:

Reference cannot be added to l because it was not built using the Windows Phone runtime. Windo开发者_如何学编程ws Phone projects will work only with Windows Phone assemblies.

I could really do with a clean slate to start with that. Kindly provide simple database connection using database with reference dll.

You cannot run SQLite in Windows Phone 7, since it cannot run native code.

Instead, use a C# implementation.

you can also use SterlingDB based on top of isolated storage, with linq support:
