Dispatcher Name not appearing in Threads window

Question

Hi All,

I am having problems with CCR dispatcher name not appearing for its threads in Visual Studio->Debug->Windows->Threads window. This occurs when I create the Dispatcher use the parameterless Dispatcher() constructor (without passing the name of the dispatcher) and then later set the Name property. If I use any of the non-parameterless Dispatcher() constructor that explicitly takes the name of the dispatcher, it works correctly. Please find a sample code below.

The following has the name of all the threads appear correctly as "MyThreadPool" in the Threads window

Dispatcher dispatcher = new Dispatcher(4, "MyThreadPool");

The following has the name of all the threads appear as "<No Name>" in the Threads window

Dispatcher dispatcher = new Dispatcher();
dispatcher.Name = "MyThreadPool";

Please help.

Thanks,

Venkat

Answer 1

Good find, this appears to be a “feature” J

Looking at the source I can clearly see that the Dispatcher constructor immediately adds threadCount workers; assigning the given threadPoolName. However, the Name property setter has no effect on the existing workers thereafter. The Name property really should be readonly.
