Q: Visual Studio 2013 started lagging during debuggin ASP .NET MVC 5.1 application Till yesterday during debugging I could freely modify views and then reload the website in the browser. But know even when I scroll it freezes completely for even 10 seconds. Sometimes works for few seconds without a lag. When I do not scroll CPU usage by VS2013 is almost 0% when I scroll it goes up to 25 and it freezes constantly.
What happenned and what can I do?

A: any anti-virus software sheduled file system checks? How much RAM installed in your computer? VS2013 minimal requirements is 1GB. Also whith OS do you run? It all sounds like you don't have enought. In my practice when usage of RAM is abount 75-80% VS begin freezes. Or if there is heavy CPU loading in background, caused some hidden processes. 

A: I am experiencing the same thing, it happens randomly. I think the problem with mine is that my laptop is extremely old and couldn't handle the process. When it does happen, closing VS and the browser and then reopen them seems to solve the problem.
