Finally Microsoft has come up with different separate wrokspace for developers of AX. If you have access to the latest build of AX 2009, you’ll notice the absence of all development related tools. Only AOT can be accessed by clicking Ctrl + D (I think they’ll move it away too). For doing all kind of development and technical things you need to press Ctrl+Shift+W to switch to the different and relatively simple UI. The good thing is you are now got rid of all of the navigation panes of applicaton and can focus now on more physical stuff.
