This normally happens when saving a very small file in a C# project/solution. I have also applied the Service Pack 1 but nothing has improved. I have nothing else running. My system is Windows 7, 4 gb of ram, over 50 gb of drive space, and an Intel I3. Also, if drop down to the Visual C# Express, will it still integrate with my Expression Blend 4? Thanks

I've usually found that when it's been really slow, it's been due to a bad plugin/add-in. Try disabling any "extras" you've installed.

1And the easiest way to do that is [starting Visual Studio with the `/SafeMode` switch](http://stackoverflow.com/questions/4182471/how-to-run-visual-studio-without-plugin-and-all-third-party-feature). – Cody Gray - on strike Apr 27 '11 at 14:24

the funny thing is I have no known plugins, only stock out of box ones from Microsoft. I am just glad I am not the only one with this problem. – heavy rocker dude Apr 27 '11 at 14:25
WPF XAML-Editor is sometimes really very slow and also slows down the whole VS 2010 environment. If I close the editor, all is OK. I have observed this on more than one machine (but always x64) and with multiple solutions. SP1 has changed nothing on this issue for me.

Some antivirus programs may cause this, as they scan whenever a file is changed. You need to add your project folders to its ignore list. Several months ago, VS was driving me crazy, as even closing a tab was taking about 10 seconds. Was thinking about upgrading my PC, but later i find out that not VS but Norton Antivirus was causing slow down.

I have the same problem with roughly the same settings. I'm on a 64 Win 7 machine and simple things like Shift+Del ing lines cause VS to pause. If I just delete a line (i.e., 'Backspace') the pause isn't there. Closing lots of open files or checking in large quantities of changes also cause major slowdowns....trying to figure out if I should go back to 32-bit as there didn't seem to be as many hiccups.

Interesting, I can't repro this. VS 2010 is smooth as butter on my 64-bit machine. I arguably even get better performance than my 32-bit machines, but I suspect that has more to do with all the extra RAM headroom available. Are you using Resharper or some other add-ins? – Cody Gray - on strike Apr 27 '11 at 14:26

If it is running smoothly, can someone provide me the exact build versions of each component on their Visual Studio? I want to ensure it matches what I got. – heavy rocker dude Apr 27 '11 at 14:29

I'm not running any add-ons is the thing that gets me. I've got 8 gigs of RAM, so I know that isn't holding me back. – Josh Apr 27 '11 at 15:14

I have the default vs 2010 with Sp1 and its works pretty smoothly on my machine Intel i3 2.4 Ghz 4 gb Ram. The only plugin I have got is the AnkhSVn one.
