title: Visual Studio 2013 Slow Build Slow Startup
body: <p>I've been having a very weird problem with Visual Studio 2013 Professional and it wasn't like this 3 weeks before. </p>
  
  <p>I have a C# solution with 25 projects all saved to my local C:\ drive. None of the project files are in my network shared drive. </p>
  
  <ol>
  <li><p>I try opening the solution, but it takes 20-30 seconds for the splash screen to show up, but it used to be fractions of a second 3 weeks before.</p></li>
  <li><p>After the splash screen, it takes another 20-30 seconds for the IDE to show up and load all my projects. But it used to take only 5 seconds 3 weeks before.</p></li>
  <li><p>I try to do a build of the entire solution (Debug or Release mode, doesn't matter) and it takes 7-10 MINUTES to complete. However, 3 weeks before, it used to take less than 10 SECONDS to complete successfully.</p></li>
  <li><p>Now, I disconnect the ethernet cable attached to my workstation and then do a rebuild (Clean and then Build) of the same solution. Essentially, I'm disconnecting from the internal network &amp; internet. What a surprise, the rebuild took less than 10 seconds to complete just like 3 weeks before.</p></li>
  </ol>
  
  <p>Questions:</p>
  
  <ol>
  <li><p>Why does Visual Studio depend on the network? (By the way I have already switched off all Source Control &amp; Team Foundation Server &amp; have not signed in with a Microsoft account &amp; switched off all settings syncing and it still did not matter).</p></li>
  <li><p>Is there a switch or configuration setting in Visual Studio 2013 such that Visual Studio will never ever need anything from the network/internet? How do I block Visual Studio from accessing the network?</p></li>
  </ol>
