How can I make it so that these messages don't show up in my output window from running my application inside visual studio (.NET) ?

These stupid error codes flood my output window and I am doing some testing and using debug.print(" ") to print out vital information about potential bugs and now I have to search for the information like a needle in a haystack because of so many of these:

"The thread '<No Name>' (0x1e24) has exited with code 0 (0x0)."

Is there a way to stop just these ^ ones ?
