title: MsBuild condition for new ("sdk-style") vs. old project format
body: <p>I want to write an msbuild "include" (.props) file that is to be imported in both the new ("sdk-style") projects as well as the old ones.</p>
  
  <p>Is there a way to find out into which type of project the .props file is imported so I could use that in a condition? For example,</p>
  
  <pre><code>&lt;PropertyGroup Condition="'$(ProjectType)'=='sdk'"&gt;
     &lt;SomeProperty&gt;SomeValue&lt;/SomeProperty&gt;
  &lt;/PropertyGroup&gt;
  </code></pre>
