ASP.NET Routing Not Working in IIS

After deploying a brand new website to IIS on Windows Server 2008 R2, I encountered numerous issues.

First, the web pages had no no styling. I could "View Source" and see that the code was correct, and I could browse to the folder containing the style sheets (bootstrap, my new obsession) and bring up the style sheet itself, but the application couldn't find the style sheets at run time on its own.

Next, none of the links worked. The page "StudentsList", which should bring up "StudentsList.aspx" returned a HTTP 404 status.

After futzing around a bit, it dawned on me that both issues stemmed from routing problems.

In no time, I found several suggestions -- including good ol' Rick Strahl's blog -- most of which pointed to the same fix. Add the runAllManagedModulesForAllRequests attribute to the <modules> tag of the <system.WebServer> section of the web.config file.

See Strahl's entry for more details:

Using Reference Aliases

I recently ran across a situation where two different libraries shared identical namespaces and class names.

I needed both libraries -- each contained some unique elements -- so I couldn't ditch one or the other. But, as I said, anytime I tried to use a class that was common (again, via the class name and namespace), I received the ambiguous reference error. This was a real problem, so say the least. However, C# provides a way to specify exactly which library (reference) you mean when you use an object that's common to two or more libraries. Simply put, you use an extern alias  statement. The concept is fairly simple: Give the reference an alias (I used the Properties windows for the reference). Add an extern alias statement, putting it before your using statements. Add a using statement, which effectively links a specific object through the extern alias statement to th
