Hello, 
 
I am developing a debugger and trying to support expressions (after  
successfully supporting breakpoints and variables). 
I've read the relevant API's but could not find any tutorial or examples  
of how to use these API's. 
I am especially having issues in 3 areas: 
1. What is the difference between Expression and WatchExpression? Which  
one should I use? 
2. After adding an expression to the view (using the ExpressionManager),  
when is it getting evaluated? What triggers the evaluation? 
3. Persistency: how do I save the expression between IDE invocations?  
IExpression doesn't have a setMarker method. 
 
Thanks and Regards, 
 
Moshe
