Debugger Not Installed While Starting C# Console App in Visual Studio Community 2017

Question

I have freshly installed Visual Studio Community 2017. I have a simple console app that prints a message. When I click the Start button I get the message

Error while trying to run project: Unable to start program

The debugger is not properly installed. Run setup to install or repair the debugger.

If I click on Debug in the menu and Start Without Debugging, I see the output of the program, so build and run seem to be working. However, I guess the debugger is not installed and I'm not sure how to install it. I've done exhaustive Google searches and seen posts talking about running regsvr32 and repair, both of which have proved fruitless.

EDIT:

Installing VS2015 fixed the problem.

@David Bradford, long time after Novell isn't it? Anyway, after looking all over the place this is the best solution I found. You don't have to install VS2015 just follow the directions below. I tried this and it fixed the problem for me and another person I was working with.
