I have installed VS 2015 RTM (nothing else) and I\'m unable to debug any solution, not matter if it\'s an existing one or a brand new one (created with VS 2015 and compiled
I have had similar issues on my svc application run on visual studio 2015, the solution was to change solution platform from "Any CPU" to "x86", if you cannot see the x86 option then click on "Configuration Manager" and go to your target project and change the platform, you'll need to select the dropdown and click "New", on the pop up, click the drop down list under "new platform" and select x86, save your changes and rebuild(See attached)
