Internal error when running visual studio project

Question

I'm building a WPF application that currently only has UI elements in place. I'm trying to use some classes I made in another project by importing a dll. When I run the wpf application, Visual Studio pops up this dialog in the Team Explorer:

The application still runs, but I don't know the cause of this error and what its effects are. Has anyone else run into this error and have some insight?

Not sure if it is relevant, but the project I'm importing is using NHibernate and Log4Net. I'm also using Visual Studio 2013 Express if that has anything to do with it.

UPDATE:

Here's the stack trace:

UPDATE 2: I removed the ViewModel code because this problem existed before I created it. I got this error when I first created a wpf application without any content. I'm looking for answers that describe what this error means or a similar situation that someone had where they were able to resolve this issue.

UPDATE 3: I started a new console application project and I'm getting the same error. This project does not use any resources from the previously described project, but both of these projects use log4net and nhibernate. I think this is an nhibernate issue.

UPDATE 4: I started a new console application with absolutely nothing to it, and I'm still getting this error. I've deleted all references and the entire AssemblyInfo.cs, and still no progress.

UPDATE 5: I create a new C++ console application and I am getting the same error. No nhibernate or anything that I thought was messing it up. There is definitely something wrong with Visual Studio...

Answer 1

Well, I fixed the error by re-installing Visual Studio. I'm still looking into what exactly went wrong, but something deep in the depths of Visual Studio must have been corrupted. Once I know more, I will update this answer to be more complete.
