<p>When trying to execute from within Visual Studio 2008 your application and you get the (uninformative) message "The operation could not be completed".</p>

<p>The solution to this is to turn off the "Visual Studio Hosting Process".</p>

<p>The problem with turning off this "hosting process" is that all the "run and rewrite" functionality is no longer available. OK, so this isn't a big deal, but I'm <em>always</em> getting this message no matter what machine I use (and it might be nice once in a while to use the rewrite and execute functionality).</p>

<p>Am I doing something wrong? How come this "feature" within VS seems to complain so readily? Do other people have success with enabling the hosting process and making use of it?</p>

I honestly have never seen this message and I work with Visual Studio for at least 8 hours a day.  Is this reproducible on other machines?  If so is there anything weird or abnormal in your code that could cause this to crash?
