[See also discussion "Dramatically poor performance on very large file" in the jetbrains.resharper.eap newsgroup] Projects may have one or a few extremely large source files. These files are typically generated. These files can sometimes be so big, that the additional R# processing makes it impossible (40 seconds or more of 100% CPU time, VS not responding to any user input like e.g. ctrl+8 or ctrl+tab) to open that file in the editor. And as these files are generated, live errors and warnings are not that important. The current option (ctrl + 8) to disable R# analysis when the file is open does not respond quickly enough. The first round of code analys seems to be finished first before it is switched of. So, the request is to offer a way to disable code analysis for specified files before they are opened. Typically, this would be done in a user and project specific setting file.
