title: Workflow 4 InArgument<List<int>>
body: <p>In Workflow 3.x you can have a dependency property List&lt;int&gt; and in the designer you could click on the "..." and add values directly to the list&lt;int&gt;</p>
  
  <p>In workflow 4, how is this achieved? Is the only way is to define a Variable type <a href="http://msdn.microsoft.com/en-us/library/6sh2ey19.aspx" rel="nofollow"><code>List&lt;T&gt;</code></a> and then using the <a href="http://msdn.microsoft.com/en-us/library/dd648043.aspx" rel="nofollow"><code>AddToCollection&lt;T&gt;</code></a> activity to add values to the list. And then pass the variable as the InArgument of the custom activity?</p>
