I've been working with VS 2010 for a few weeks with no problems after upgrading to Win 7 64bit. My solution (a windows forms database project using ADO.NET to view and manage a SQL Server DB) has been compiling and running fine throughout.
I just finished deleting and re-placing a Dataset in the project inorder to make it current with changes made to the SQL database.
The solution still compiles and runs fine.
However , the problem is in the VS IDE - in design mode, I cannot see one of the main controls ( a custom UserControl) that is contained in a GroupBox container. All the code to generate the component exists in the designer, but when I look at the Document Outline, it does not exist. It is not "Sent toBack" or anything.
Also, I did get an error once when trying to save changes while in this condition, error message something like " could not load the file or assembly XXXXXXXXXX ."
All my Google searches come up empty.
All the code to generate the component is still there - it's just not loading into the IDE for some reason.
