Visual Studio 2013 - won't debug

Question

Alright, so I've had this problem for weeks now and I've been searching around with Google and I've found nothing useful, so this is more or less my only chance to find a proper solution.

 

For some reason I can't debug the application. Well, yeah - it starts up, but never actually launches the application.

This is the output I get:

 

The thread 0x8e0 has exited with code 259 (0x103).

'MyProject.WinForms.vshost.exe' (CLR v4.0.30319: MyProject.WinForms.vshost.exe): Loaded 'C:\Users\myusername\Source\Workspaces\Workspace\MyProject\MyProject.WinForms\bin\Debug\MyProject.WinForms.exe'. Symbols loaded.

The thread 0x1024 has exited with code 259 (0x103).

The thread 0x8d8 has exited with code 259 (0x103).

The thread 0x5e0 has exited with code 259 (0x103).

The program '[7792] MyProject.WinForms.vshost.exe' has exited with code 0 (0x0).

 

If there's something you need more details about, or any questions at all, please let me know.
Help or tips will be appreciated.
