Resharper “Cannot resolve symbol” when the code well-compiled

阅读更多关于 Resharper “Cannot resolve symbol” when the code well-compiled

I believe, the error message not related to Serilog specifically, but is rather because of the code/assembly/package specific structure/modifiers etc. So, the issue is that Resharper shows the error (and the code (from assembly referenced) is not accessible for navigation to) when Visual Studio navigates (by Go to Definition command) to metadata and compiles the code well (including, showing the method description successfully as well). The method is defined in assembly as follows: namespace Serilog { public static class Log { public static ILogger ForContext<TSource>(); My current version of

How do you get Vim to highlight C++ syntax errors like Visual Studio?

阅读更多关于 How do you get Vim to highlight C++ syntax errors like Visual Studio?

问题 Is it possible to get gVim to highlight C++ syntax errors (the red squiggles underneath) in real-time like Visual Studio? 回答1: Short answer: Yes, but it won't be so smooth / immediate as in IDEs. Long answer: Whereas IDEs have built-in support (and parsers, etc.) for a (usually very limited) set of programming languages, Vim is a general-purpose editor, and therefore has to rely on external tools to do the syntax checking. The built-in way is to execute :make and receive a list of (syntax or
