I'm using crank to load test my signalr application. The command that I'm using is as follows
crank /NumClients:100 /Url:http://localhost:29573/TestConnection /BatchSize:10
I'm getting an exception in my powershell window as follows...

I do have the sample application: SignalR.LoadTestHarness running at localhost:29573. This is the same application that is found in the SignalR source code samples.
What am I doing wrong?
You did not provide the ControllerUrl parameter and as a result crank is trying to create a hub connection with null Url which results in throwing a NullReferenceException on this line.
I am working on an application that need to do asynchronous tasks.
I use two times the code given at http://msdn.microsoft.com/fr-fr/library/system.web.ui.page.executeregisteredasynctasks.aspx
I simply copy and paste it in my application.
Unfortunately I have an error thrown on one time while the other one works perfectly.
The error is :
Object reference not set to an instance of an object.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
