Recently, I have been trying to install some code on a brand new server running Windows 2008 R2 SP1 and .NET 4.0. However, I kept running into the following error: Error: The configuration section 'microsoft.applicationServer' cannot be read because it is missing a section declaration
There are many resources out there talking about adding various things. It turns out that what I was missing was AppFabric.
Ouch! I wasted a lot of time on that one.
