I am getting fed up with this error. I have search all over the web and tried every possible suggestion to this error I could find.
In the end I even tried the command line and get the following stacktrace.

To fix "Object reference not set to an instance of an object," you should try running Microsoft Visual Studio as an administrator. You can also try resetting the user data associated with your account or updating Microsoft Visual Studio to the latest version.
To resolve this, modify the Application Pool identity of IIS: Open IIS Manager. In the Connections pane, expand the server node and click Application Pools. On the Application Pools page, select the application pool that you want to specify an identity.
You can eliminate the exception by declaring the number of elements in the array before initializing it, as the following example does. For more information on declaring and initializing arrays, see Arrays and Arrays. You get a null return value from a method, and then call a method on the returned type.
This error's description speaks for itself but when you do not have much experience in development, it is very difficult to understand. So, this error description says that an object that is being called to get or set its value has no reference. This means that you are trying to access an object that was not instantiated. Why should I know this?

Please make sure there is not build error in your ASP.NET project.
This error was occurring for me when I tried to compile the project with MSBUILD - it would build fine within Visual Studio, and would even Debug in my local browser. The Publish option within VS worked, as well. But the command-line MSBUILD was causing the project to error out every time.
I managed to fix this problem in VS 2012 by opening the Property Pages on my Website, opening the 'MSBuild Options' tab, and unchecking the 'Allow this precompiled site to be updatable' option, then hitting 'save all'.

This typically happens when a *.dll.refresh file in the bin directory points to a location that is no longer available. Deleting the *.dll.refresh files should resolve the issue.

I had the same experience and removing the compressed flag from the solution directory tree, set the compiler working again.
