title: I can seem to get msbuild to build unsafe code blocks
body: <p><code>msbuild</code> doesn't seem to allow me build <code>unsafe</code> blocks even though my <code>.csproj</code> specify:</p>
  
  <pre><code>&lt;PropertyGroup Condition=" '$(Configuration)|$(Platform)' == 'Debug|AnyCPU' "&gt;
      ...
      &lt;AllowUnsafeBlocks&gt;true&lt;/AllowUnsafeBlocks&gt;
  &lt;/PropertyGroup&gt;
  </code></pre>
  
  <p>my build command is:</p>
  
  <pre><code>msbuild myProject.sln /p:Configuration=Release /p:Platform="Any CPU" /t:Clean,Build
  </code></pre>
