title: Gac installation issue
body: <p>I'm following <a href="http://learn.iis.net/page.aspx/804/developing-a-custom-rewrite-provider-for-url-rewrite-module/" rel="nofollow">this example on creating a custom url rewrite provider</a>. Everything is building fine, but for some reason nothing is getting installed in the gac. Here's what I've tried in the "Post Build" command:</p>
  
  <pre><code>CALL "%VS100COMNTOOLS%\vsvars32.bat" &gt; NULL gacutil.exe /if $(TargetPath)
  
  CALL "%VS100COMNTOOLS%\vsvars32.bat" &gt; NULL "C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\NETFX 4.0 Tools\x64\gacutil.exe" /if $(TargetPath)
  
  "C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\Bin\NETFX 4.0 Tools\x64\gacutil.exe" /if $(TargetPath)
  
  gacutil.exe" /if $(TargetPath)
  </code></pre>
  
  <p>The last one actually fails with code 9009 so the third one was used to fix it. The first two I'm totally clueless about. They don't fail, but don't seem to do anything either. The 3rd actually seems to work but navigating to c:\windows\assembly doesn't list my dll in there and when I try to add the provider in IIS it says it can't find it in the gac. My assembly is strongly signed. Any idea of whats going on? </p>
