View 1 RepliesI have a project that I developed in VS2005 and that has been put into VSS. I am trying to "get" it on a new machine and convert it to VS2008 because that is what is installed on the new machine. I am having problems with it that I think originate in its working folder. So my basic question is, when you try to work with a solution that's in VSS should you maintain the same folder structure that it had when it was originally checked in? I'm not particularly happy with its original structure because it goes on and on seven levels deep, and I wanted to just cut it down to C:ProjectsResNew, but if that's what it takes to get it to work, I'll do it.

I'm reading this web service from a silverlight application with the following code (this application works but, it doesn't show all the employees as it skips over when no tag is present):
