DataSet Debug Problem

Well please advide.

I have a project named Project1. I create one Dataset named Ds. When i debug the project i take an error from the compiler. In the code the error is in compenets declaration as ahown above

this.ds = new Project1.ds(); 

If i delete the underline Project1 in the code and debug again it works perfect.

Every Time i am making a change in the dataset i am taking the same error message.

What can I do to avoid this error?

Shall not use the drag drop componets for creating database objects?

It is better to write all the Code in Ado.Net by Hand?

Please Advice!!!!

Thanks in Advnced.......
