Closed Issue: Request time limitation is too strict [5064]

Sometimes I encountered "The operation has timed out" exception. It is a fact that my net speed to RTM is slow.
This issue has been resolved after I directly modified my local copy of IronCow source code at Rest\RestClient.cs, line 55. origin this line is Timeout = 5000, I changed it to 50000.
My fixing is not good enough. It is better to set a configuration item for time out.

Here are exception detail in encountered when call rtm.CheckToken(storedToken, out auth).
System.Net.WebException was unhandled
Message="The operation has timed out"
