SQLite

   Is SQLite DB fully supported in DF 2010 in .Net 4

When i ran this code it gave me this error. 

public static SysUser GetUser(EntityManager pManager, string pUserName)
{
try
            {
                var mgr = new eFilerDBEntities(pManager,true);
                var aUser = mgr.SysUsers.Where(p => p.UserName == pUserName).FirstOrNullEntity();
                return aUser;
            }
 catch(Exception p) 
            {
                throw p.InnerException;

            }           

        }

Throws this Error:

"The underlying provider failed on EnlistTransaction."

I using SQLite data base.
