title: ASP.NET - Common Gotchas
body: <p>When I am working with ASP.NET, I find that there are always unexpected things I run into that take forever to debug. I figure that having a consolidated list of these would be great for those "weird error" circumstances, plus to expand our knowledge of oddness in the platform.</p>
