VS2010 Not Always Building Before Debugging

I have had a problem where VS2010 will not build my projects before debugging. Even when they have never been built before (i.e. on a fresh checkout from source control).

I will either find I am stepping through on the wrong lines of code (because the symbols are out of date), or an error message if there is no build output (bin\debug folder is empty).

Performing a build manually before debugging is the workaround.

What resolved the problem for me was going to the configuration manager and making sure the "Build" checkbox was checked. In my case, it had somehow become un-checked:

Go to the configuration manager, and change Debug->Mixed CPU to Debug->Any CPU, I had resolved mine with the same option.

Update: I've found your answer and checked a Tools->Options->Projects and Solutions->Build and Run And a value of "On Run, when projects are out of date" is "Prompt to Build", but VS does not prompt! But then I found a problem in "Configuration Manager" - for some reason a mark "Build" disappear. It happened to my projects when I create a some project based on some another one using a copying a files and changing a project's and solution's GUIDs, names etc. inside a proj/sln files manually.

I'm answering this myself, so that Stack Overflow can be the canonical answer to this problem in case someone else experiences the same thing.

Essentially it's a VS configuration issue. Navigate to the options as follows:

Tools->Options->Projects and Solutions->Build and Run->On Run, when projects are out of date:

and make sure it is set to "Always Build" if it is not already.

Hope this helps someone, it's caused me a lot of trouble for weeks now.
