Ever had this error?

changes to 64-bit applications are not allowed

This occurs on 64-bit machines when trying to do Edit and Continue (a feature of the .NET CLR) on a 64-bit application.

It’s only available on 32-bit applications.

Now it’s up to the reader to determine if he needs a 64-bit application. 95% of the time the answer will be no.

So for those people I present the solution:

It’s quite simple. Go to properties, build and set the platform target to x86. And you’re ready to go Edit and Continue.

Please do read this about Edit and Continue.
