weak-references

I've got a strange behavior here: I get a massive memory leak in production running a WPF application that runs on a DLOG-Terminal (Windows Embedded Standard SP1) that behaves perfectly fine if I run it localy on a normal desktop (Win7 prof.)

After many unsucessful attempts to find any problem I put one of those directly beside my monitor, installed the ANTs MemoryProfiler and did one hour test run simulating user operations on both the terminal and my development PC.

Result is, that due to some strange reasons the embedded system piles up a huge amount of WeakReference and EffectiveValueEntry[] Objects.

Here are are some pictures:

Development (PC): enter image description here

enter image description here

And the terminal: enter image description here

Just look at the class list... enter image description here

Has anyone seen something like this before and are there known solutions to this? Where can I get help?

(PS the terminals where installed with images prepared for .net4)

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
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
