.NET

I'm using the CLR debugger (version 8, from "Visual Studio 2005") to debug some C# code. I can step through my code, but for many variables, the debugger won't show me its value. That is, if I type it in the "Immediate" frame or add it to the "Watch" frame, it says "Unable to evaluate the expression.".

It seems to do this a lot for var variables, but I'm also seeing it for parameters and properties, too. I have not been able to figure out what the pattern is.

Is there a rule for when it can display the value of a variable? Is there something I need to do to my code, or in my build script, to make the debugger able to view variables? Or is there a hidden debugger setting?

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
