Generate the publication of my webforms application (framework 4.5.2) and upload it to an IIS 7.0. The content without interaction with the user works well, but at the time of entering the login I find the following error "Object reference not established as an instance of an object. Check the lines that inform me and appear correct.
On the other hand, if the solution "sln" of the app I execute it from the same IIS works without problems. What can be??? "
