Working with a fairly large VB.Net back office winforms application. 1 million+ LOC. Big ball of mud, 90% of all code is in Forms & other UI controls.

Slowly introducing better architecture as time & recources allows, We've been using ideas from the EventAggrgator by Jeremy Miller.

Initially I stripped out the usage of SynchronizationContext. Now I'm trying to introduce it back, and I'm struggling with the translation of the lamda stuff from c# to vb.net.

Specifically this line of c#

_context.Send(delegate { receiver.Handle(subject); }, null);

This is the vb.net I have so far:

_context.Send(New SendOrPostCallback(AddressOf listener.Handle(message)), Nothing)

The error I'm getting is

listener.Handle(message) <-- AddressOf operand must be the name of a method.

I'm sure I'm missing something simple, but after staring at this for 2 days, I'm lost.

Is this thread-safe? The EventAggregator in Prism is a very simple class with only one method. I was surprised when I noticed that there was no lock around the null check and creation of a new type to add to the private _events collection. If two threads called GetEvent simultaneously for the same… >>> More
