I have been using VB.NET for 2 years and have completed many
applications.

Recently I have experienced problems using the dataset designer and at
this
point I cannot use it at all. It began when I added a column to a table
in
the dataset designer and when I returned to the windows designer, all
the
objects were gone and an error message was on the form.

At this point, I cannot generate a dataset without getting the error,
"There
were problems generating dsMyDataset. To resolve this problem build the
project, fix any errors, and then generate the datatset again."

I tried creating a typed dataset by adding a dataset using the Add New
Item
method as was suggested in another posting, but the added dataset does
not
appear in the dropdown box as an option.

Is it an update the could have caused this problem? How can I get it
back
to the way it worked before?
