i've seen other threads dealing with at least parts of this problem so we (our project team) sure are not the only ones encountering it. but since i've never found a satisfying answer over months now i'd like to start a new thread for this.
in (almost) every webpage resharper (got the newest 259 release) is underlining dozens, sometimes hundreds of errors in code that is absolutely correct and compiles just fine. this includes the use of any user controls as well as the use of functionality from a referenced class library. this already starts at the top where resharper underlines the using statements as invalid and continues throughout the pages and controls underlining every use of a non asp-native user or server control (declared in the aspx/ascx file). i attached a screenshot - and let me add that the solution in the screenshot compiles with no errors.
concerning class libraries i know about a bug with public generic methods (but of course avoiding them is not an option); concerning user controls i have no information at all. all i can say is that we are doing casual asp.net development and resharper can't handle it at all.
now of course you can't work with 600 to 700 errors highlighted on one page with 1000 lines of code, so we turned of this function. unfortunately reformating and refactoring the code doesn't work properly eighter - so resharper currently is totally useless.
what i'd like to know is whether there's something we're doing wrong or if this is a know issue and if it is, when it's going to be solved. as a web developer i need resharper to work properly with asp.net - otherwise i'll have to get rid off it.
