Using latest source code I get an error ("parameter's type doesn't match cached parameters") on creating or editing a blog post (in debug). The problem is the incorrect data type in this line in DBBlog.UpdateBlog:
sph.DefineSqlParameter("@IncludeImageInExcerpt", SqlDbType.NVarChar, 255, ParameterDirection.Input, includeImageInExcerpt);
Stored proc mp_Blog_Update has @IncludeImageInExcerpt bit
This didn't prevent the overall save from working, but we get no error if the above line changes to
sph.DefineSqlParameter("@IncludeImageInExcerpt", SqlDbType.Bit, ParameterDirection.Input, includeImageInExcerpt);
