In my Silverlight app, I made some test with the RadTabControl.
When I open a tab in the first time, I see that the memory increase with a big amount (A).
Then, I close it, the memory decrease but with smaller amount (20% of A).
And when I open/close the tab again in many times after, the memory also increase/decrease in range of 20% (of A).
The problem is that I have many different tabs, if I open too many of them, the used memory will be very big.
I don't know why it didn't release all memory. And I hope your help to resolve it.
