When finding new jobs and looking at resumes you commonly see that someone expects or has experience with .Net. But what does that really mean? It seems that my current employer expected it to mean that I was familiar with the ASP.NET controls (GridView, etc) when in reality I had never used any of them before. I had used C# for 6 month...
