Sometimes CodeRush/DXCore plug-ins may not be loaded correctly. Here is a brief instruction if you’d like to investigate and fix the loading of the plug-in in question.
The Startup options page from the Core category allows you to tweak the IDE Tools start-up settings. The page level is expert, so do not change these options if you do not actually need this. Here is what the options page looks like (click the image to enlarge):
DXCore has a built-in Loader Engine, which is intended to improve the speed of its start-up process. However, the first DXCore start-up process is pretty long (it may take a minute or two). There’s a reason that the first start-up takes much more time then the subsequent launches. When DXCore loads for the first time, it has to load all of the plug-ins found in both, “System” and “PlugIns” subfolders. At this time, DXCore profiles every loaded assembly: checks its load type, loading time, so in brief, all important and necessary information that DXCore should know about a particular assembly. All this information is saved to Loader profiles in an XML format. This information will be used on every subsequent DXCore launch, so that Visual Studio should start instantly, because, in the first place, plug-ins are loaded from profiles only after the splash screen goes away and, secondly, because Loader Engine has optimized DXCore loading process specially for your system.
