Invalid dataset name

I made a dataset using bindingsouece and wizard. Later I deleted it from my form, from the list below. When 开发者_开发问答I needed to make dataset with same name, it gave error that dataset name is invalid as it already exists. Why is this and where do I need to delete it to be able to use the same name again? Thanks Furqan

The dataset would have been created and added to the project by the wizard - look for a file by the name of the dataset with a .vb suffix. You can delete it with all associated files.
