VS 2015 Update 1 - Claiming I am debugging a release build

Question

After updating to VS 2015 update 1, if I run a web project (MVC), stop the application, then try to run it again, VS stops and pops up a dialog claiming

You are debugging a Release build of <myproject.dll>.

Using Just My Code with release builds using compiler optimizations results in a degraded debugging experience (e.g. breakpoints won't be hit).

The problem is I'm not running a release build. I'm clearly running the (same) debug build I just ran! Why does VS think I'm running a release build?

Cleaning the solution and re-running clears the error message, so something is hosed somewhere.

Answer 1

The word from Microsoft is that this is a known issue (it originally went to the Debugger team, but was determined it was a build issue, and is now in the Project system team's hands. There are other bugs open on this issue, and it's rated Priority 1, so should be on track for the next update. Though as would be expected, no promises can be made as to when it will be released (or what is actually in the update).

So. It's known and is being worked on. At least turning off the “Enable Just My Code” in the Debugging General Options seems to be a work around for now.
