Visual Studio 2010 debugging ASP .NET MVC 2 app is slow

Asp .NET MVC 2 apps started from Visual Studio 2010 are damn in my opinion. It takes 2-5 seconds to refresh or open a new page. Do you have the same problem? Do you know if this ASP .NET MVC 2 debug mode can be somehow sped up?

I work at 64 bit computer, Windows 7 and Visual Studio 2010.

Are you talking about initial page load (after a build) being slow, or every page load? - kbrimington
I've developed several MVC applications but there's no reason for Visual Studio to run slow. You have to be using some strange server configuration. But as @kbrimington said, this may be due to .net compiling the assembly after it was changed and first run. But this is the same for any .net application. - Robert Koritnik
I find that running my site in IIS proper is much faster for page reloads than the stock dev server (cassini). No idea why that is, but I always develop against local IIS. - Kirk Woll
@kbrimington - I am talking about every page load. @Robert Koritnik - I haven't changed anything in my server configuration. However I believe that MVC apps started from VS2008 are considerably more responsive than those run started from VS2010. @Kirk Woll Can you elaborate a little bit on how to develop against local IIS? - mgamer
I totally agree - I have been wondering about this - I have 300k pages that take forever to load using VS2k10 and I never had a problem with VS2k8 - it's very frustrating. My specs are the same as yours. - Rob

I had problems with slow Visual Studio debugging when "Native Code" debugger was enabled. Try disabling it if it is enabled.

On "Visual Studio 2010" go to:

  1. Project Properties ->
  2. Web ->
  3. Debuggers (bottom of page). ->
  4. Disable all exept ASP.NET

Hope it helps.

For me, disabling 'Edit and Continue" fixed the problem.

Menu.Debug.DeleteAllBreakpoints often works, but I still don't know why.

Turn off Intellitrace. Your MVC debugging will go much faster:

  1. Click on Tools>Options>Intellitrace.
  2. Uncheck "Enable Intellitrace".
  3. Click OK
  4. Restart debugger.

Good luck!

Just came across a similar problem.

I was having a standard ASP.NET and a ASP.NET MVC project in the same solution. 2 development web servers were starting when I was running the debugger.

I just unloaded the standard ASP.NET project (containing a test page and which I did not really use) and everything is now a lot faster.

Hope this helps!
