Due to the async nature of http access via WebClient or HttpWebRequest in Silverlight 4, when I want to do multiple http get/posts serially, I find myself writing code that looks like this:

doFirstGet(someParams, () =>   
  {
    doSecondGet(someParams, () =>
      {
        doThirdGet(...
      }   
  });

Or something similar. I'll end up nesting subsequent calls within callbacks usually implemented using lambdas of some sort. Even if I break things out into Actions or separate methods, it still ends up being hard to read.

Does anyone have a clean solution to executing multiple http requests in SL 4 serially?

I don't need things to be synchronous, I just want serial execution.
