问题
I'm Trying to publish a website, using Visual Studio 2013. I'm getting an error:
ASPNETCOMPILER(0,0): Error ASPRUNTIME: Object reference not set to an instance of an object.
It happens also on Visual Studio 2010.
I tried to restart VS, and PC.
I removed *.dll.refresh from my bin directory.
I don't have <clear/> tags in my web.config.
I think it all started when I accidently removed my *.suo file.
Any ideas?
Update:
I just noticed it happens only when I try to precompile my site. If I publish without precompilation it works fine...

OK. After wasting so many hours I somehow got to this blog: http://thesoftwarepractice.net/development-things/object-reference-not-set-to-an-instance-of-an-object
Turned off the McAfee Real Time Scanning and its works...

I also had this problem and it was not solved by any of the ideas mentioned previously. The problem was that somehow compresssion had been enabled on the subfolder of my drive containing the ASP.NET website. The solution is to right-click, choose properties and in the general tab, click Advanced and under the 'Compress or Encrypt attributes' section, make sure 'Compress contents to save disk space' is unchecked. Upon prompting do this for all files and subfolders (note it may take some time). Hope this helps someone.

Have you tried creating a new website, adding all the files from old website to the new one and adding all the references used?

I also had this issue, and I fixed it by clearing and re-configuring all the dependencies and the dll's of the project.
