Parser error or Dataset Error or Namespace Error

I am new to ASP.NET and I am currently learning to use the VS 2005 Express tools. I've been able to get along smoothly for sometime; getting bugs and resolving them from your very valuable posts in this forum.

Now I have a problem that I have no idea where to begin to resolve the problem. It appears to be a Parser Error, but then when I try to view my pages, I get a lot of other apparently related errors. I am suspecting that I have, one way or the other, messed up my dataset schema definition. The strange thing about this error is that I cannot open any other pages anymore. Even those simple and almost empty pages that have no dataset references to them. It has completely paralyzed my whole design effort. All was working fine and all I remember having done was update the TableAdapter definitions. What have I messed up here? Please review the below error copy and see if you can help me:

I didn't see this post before and created a new one.  Have you solved this issue?  If so can you please let me know.

Yeah, just ran into this problem as well...  As far as I know this is the only reference to it.  Perhaps reubilding the DAL is an option and hoping it doesn't recurr.

Probably you have received this error after adding some additional code (also in the designer). Try to remove all code that you added before the error and try to build again. 

If this doesn't help try to clean/rebuild the assembly. If you are using xsd in your App_code folder the clean and rebuild are not available. Try to delete the temporary generated code in folder

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\[web_folder]

Then build  the site again ... or just refresh the browser.

Hope this helps
