title: Documentation for Windows Workflow Foundation Workflow Expressions
body: <p>I would like to use a little more advanced expressions i Windows Workflow Foundation (WF) workflows but I cannot find any reference to what kind of expressions that actually are accepted. Some kind of Visual Basic syntax is used, but what kind? Where is the online reference documentation?</p>
  
  <p>What I would like to do is to read files, split strings, create and call .NET objects etc.</p>
  
  <p>Thank you all for any help with this!
