Coded UI Test can't access BrowserWindow or DOM inside of it

Question

I have a coded ui test project that I created from scratch (no recording, its for a massive MVC site so I needed it to be really organized) and it's running perfectly when I run it from the VS 2012 Test Explorer. When i try running it from an external console application, however, the instance of BrowserWindow is acting funky(and not in a good way).

My test while trying to work through this is just having these lines at the beginning of the test method:

BrowserWindow browserWindow = BrowserWindow.Launch(new Uri("whateverurl.com"));
Mouse.click(browerWindow);

When i run it from the console application the click throws an error about the control being blocked.

If i try running anything like:

browserWindow.ExecuteScript("return true;");

I get a UITestException "Specified cast is not valid" (this also works fine from the Test Explorer).

I have made sure that playback is initialized in the console application and that the instances of Browserwindow look the same in the debugger from running it in both the console app and test explorer.

Anyone know what might be causing this?

Also, i tried creating a separate coded ui test project, recording some actions, and running it from a console application and it worked perfectly fine — Sh'dynasty, Jan 14 '16 at 15:59

As per this answer, i tried adding [STAThread] attribute to the main function and it now works.

c# specified cast is not valid while assigning mshtml.HTMLDocument.frames
