DevExpress Menu Disappearing
Typically the menu disappearing is not an evaluation issue. Instead this is the normal behaviour of CodeRush Xpress.
This menu can indeed be brought back. This needs to be done for each Major version (2 - 3 of these each year). Here are the instructions for doing so with 10.1
However it may be enough to know that the options are available through the use of the CTRL+SHIFT+ALT+O shortcut
CodeRush Xpress
The Xpress of CodeRush is not an evaluation version although it is a cut down version.
(Trial of full version of CodeRush available here)
It is Free to use with VS2005, VS2008 and VS2010 because Microsoft paid DevExpress to licence it to every user of (the Pro versions and higher of) these products.
Along with this, Microsoft also wrote several conditions into this agreement.
The first of these appears to have been the removal of the DevExpress menu from the main menu bar.
Additionally in version 10.1 and higher (required if you want to use CodeRush Xpress with VS2010) several other functions were also removed at the request of MS (but only whilst running under VS2010 - these functions remain whilst using 10.1 with earlier versions of Studio)
This is indeed a shame but as MS paid for this product they are entitled to have a say in what goes into it.
