title: Why is Visual Studio 2012 not giving me errors where they should be?
body: <p><strong>EDIT</strong> I started a new console application to see if the features in question would work, and they did flawlessly. I guess the issue is now <strong>why are they not working when I check out file for edit in TFS</strong>?</p>
  
  <p>I just downloaded Visual Studio 2012 and after some digging I am still having some issues. Visual Studio is not giving me the errors (red swiggly lines under the code) where they should be. I made a bogus using statement to illustrate:</p>
  
  <p><img src="https://i.stack.imgur.com/a1iKs.png" alt="enter image description here"></p>
  
  <p>The last using statement obviously isn't valid, so why isn't it telling me so?</p>
  
  <p>Another example:</p>
  
  <pre><code>public String method()
  {
      someVar = "hi";
  }
  </code></pre>
  
  <p>Even though I have no someVar variable set anywhere within scope, there is no error. I am using classes obtained via T.F.S., though I doubt that matters but just in case it does I thought I would mention it.</p>
  
  <p>It should also be noted that I do have intellisense capabilities enabled yet those are not functioning either.
  How can I fix this madness :-)?</p>
