Solution

Go to Project Properties and uncheck Native Code in the Debuggers section of the Web tab.

EDIT: Changed for ASP .Net

Problem

I get the error changes not allowed when unmanaged debugging is enabled Actually I get the below message but Google doesn't return many results changes are not allowed when unmanaged debugging is enabled What does this mean? How do I fix it? Note this is an ASP.NET project. Checkmarking Edit and Continue does not make this error go away.
