Object Reference Not set to a reference of object

Object Reference Not set to a reference of object

  
Hi Everyone,

I am currently unable to publish my application. When I try to publish I get the following error:

Invalid compiler output. Object Reference not set to an instance of object.

My application has no references and no extensions. Although I do have several imported entities from excel, which I have re-imported. 

Any thoughts?

Thanks.
Hi Evan,

If you look in Service Center, do you see a more detailed error? If not, can you copy the error from Service Center? There's typically more information presented than just a single line, which may help determining the cause.
