sharepoint custom workflow activity is doing nothing, not even log messages - sharepoint

Question

I am trying to create a custom workflow activity which gives me the list of recipients that I am storing in list. But once I deploy and start the workflow nothing is happening, not even log messages are coming. So i tried to debug the code but breakpoints are not set and I am getting the error "The Breakpoint will not currently be hit. No symbols have been loaded for this document." Can anyone please help me to deal with this issue.
Below are the steps I have followed in creating this activity.
1. created a workflow activity library.
(please find my code file attached)
added .dll to GAC
updated web.config and WSS.actions files.
Now I see the action in designer, so i have created a workflow using designer.
strted the workflow manually on an item.
Here nothing is happening, not even an error. Please let me know if you need any further information.
Please find the code below.

Answer 1

I am not sure if this will help but you could try changing the following line in your code from this:
SPSecurity.RunWithElevatedPrivileges(elevatedExecuteMethod);
To this:
SPSecurity.RunWithElevatedPrivileges(delegate(){
ExecuteMethod();
});

Another shot-in-the-dark reply:
Try changing the class you're inheriting ( http://msdn.microsoft.com/en-us/library/ms173149(v=VS.80).aspx ) from SequenceActivity to Activity (SequenceActivity inherits from CompositeActivity, which itself inherits from Activity. See: http://msdn.microsoft.com/en-us/library/system.workflow.activities.sequenceactivity(v=VS.90).aspx )
If that doesn't work, try removing your constructor entirely. You should be able to use the base (Sequence)Activity constructor (since you're inheriting the class, not implementing it)
Hope that helps...
