Thanks for reply.
Our application has 30 different map layers and this layers can be visible on sametime (this is depends on users choice)
I opened my silverlight application and select 10 layers on sametime (vector, imagelayer or tiledlayer) , and i just changed extend, zooming in and out again and again and again...... Thats what all we do.
Memory usage of Internet explorer is continuously increasing, and than reaching 1.4 GB and finally our application is frezees until restart Internet Explorer.
What can be wrong with our application?
We compiling application as AnyCPU already. But i'm seeing Internet Explorer as x32 (explorer*32.exe) on my task manager. Our Internet Explorer is x64.
