Using VS 2013 and .net 4.5.1 but still getting “Changes to 64-bit applications are not allowed”

I'm using VS 2013 Ultimate with Update 2 on Win 8.1 x64 and VS won't let me use edit and continue on a simple console application. The console app is set to use .net 4.5.1 and AnyCPU but whenever I try to change code while debugging I get the dreaded "changes to 64-bit applications are not allowed" message box.

I've tried making sure Edit and Continue is enabled in Tools->Options. I've tried flipping it off and on again...no good. I've tried disabling all my VS extensions...didn't make a difference. I've tried resetting to the default VS settings...nope. I've tried repairing my VS installation...nothing. I've tried verifying my .net framework installation...it says my installation is verified but I still have the same problem.

Anyone else seen this?

No, question 1498464 is about VS 2008. x64 Edit and Continue was added in VS 2013 but it's not working on my machine. This is a different question. – J. Allen

That's for web sites, this is a console application. – J. Allen

My crystal ball says that your debugger is using an older debugging engine. Another side effect is that you would have never seen the new method return value debugging feature.

Tools + Options, Debugging, General, untick the "Use Managed Compatibility Mode" option. This option is actually only required to revive C++/CLI debugging.

Terribly annoying message "Changes not allowed while unmanaged debugging is enabled" and "Changes to 64 bit applications are not allowed". I was successful many times when I tried the following steps:

  1. Project Properties >> Debug tab >> UNCHECK "Enable native code debugging"
  2. Tools >> Options >> Debugging >> General >> UNCHECK "Use Managed Compatibility Mode"
  3. Tools >> Options >> Debugging >> Edit and Continue >> Check Enable Edit and Continue >> UNCHECK Others
