NEW in 3ds Max 9: Not all ActiveX controls have been recompiled for the 64 bit versions of Microsoft Windows. Various areas of the 3ds Max User Interface rely on ActiveX controls like TreeView and ListView. To provide an alternative implementation of these and other controls, 3ds Max 9 adds access to DotNet Classes, Objects and Methods and provides a dotNetControl User Interface Control to use in MAXScript Rollouts.
Note on DotNet Performance:
Since DotNet uses a Just in Time compiler (JIT), the first time you load or execute any managed code, the Common Language Runtime (CLR) will compile the Intermediate code into machine language code, causing a significant performance hit. The second time the code is executed in the same session, the JIT compiler will use cached binaries instead of compiling the code again and the code will execute much faster.
So for instance, the first time the Named Selection Sets tool is opened, it can take several seconds for the dialog to open. The second time it would open instantly.

The Named Selection Sets editor dialog has been updated to use a DotNet TreeView control instead of an ActiveX control. It is a good example of using Drag And Drop in DotNet TreeView controls.
