title: Using external assembly's method's results as a dataset
body: <p>Using SQL2008R2:
  I am trying to create a dataset that is simply the result of an external assembly's return method(s), but everything I can find regarding using custom/external assemblies just has a textbox's value set to the external assembly's method's result via an expression.</p>
  
  <p>I simply want Report Server to do the data processing in the external assembly and bind that result to a very simple report.</p>
  
  <p>I found some references to something about MDX but they seem to be a few years outdated and needed to know if this is possible.</p>
