I've recently inherited an ASP.NET 2.0 project from other developers and they have a LinqToSql datacontext with stored procedures. I've been asked to modify one of the SPs which is essentially just adding a couple columns to the database table and then those to parameters to the SP. So I delete the existing SP from the L2S context and drag in the new one with the additional fields, and all hell breaks loose. Suddenly I get over 20 errors! What seems to have occured is L2S has modified many other stored procedures that I haven't even touched and changed the return type from ISingleDefault<some object> to int. I've never used stored procedures before with L2S so I don't know if this is standard behavior or not. Does anyone know why this has happened and how to fix it to set the correct return type?
