Have been learning ASP.NET (using C#) over the past few days.

I have made everything as I need it, now realised one of my datatypes in the database needs to change from an int to a bigint. I managed to change that fine in all the tables, but my queries that call Table Adapters still are looking for an int not a long / bigint.

Could someone tell me how to update the datatypes in a dataset / table adapter please to match the database schema.

(Not sure if it makes much difference but I am using Visual Studio 2010)

Thank you 🙂
