Im currently working on a monolothic ASP NET MVC 5, .Net 4.6.1 web app and i have problems with the debug startup time in JetBrains Rider. When using Visual studio 2017 it takes around 60 seconds for the entire web app to start but with Rider it takes atleast 3 minutes. I havent changed the default debug settings. We are using entity framework with lazy loading. Generally everything seems slower when using rider to debug, I have tried to disable resharper build.
