Visual Studio 2010 hangs when starting asp.net site debugging - asp.net

i have problem with Visual Studio 2010 on Windows 7 x64. When i started asp.net site debugging, it stoped working. Only solution is restarting IIS.
Have anyone experiences with this?
Thanks

As Peter mentioned, manually attaching through the Attach to Process dialog should work.
Another option is to temporarily update your project to .NET Framework v4.0. In the IDE, this can be done in 'Build' section of under project properties.
We are still investigating the issue to find a longer term solution.
Sorry for the inconvenience that this problem has caused.

This M$ Connect article points straight to the topic: http://connect.microsoft.com/VisualStudio/feedback/details/556000/vs-2010-hangs-when-debugging-asp-net-3-5-web-application-or-website
Apart from the different intermediate solutions proposed, there seems to be an official Microsoft VS 2010 HotFix available here: http://archive.msdn.microsoft.com/KB2106584/Release/ProjectReleases.aspx?ReleaseId=4834.
HTH

Here's a workaround that helped me:
Go to Debug->Attach to Process. If the 'Attach To' box says 'Automatic: Native code' then click the 'Select...' button. In the 'Select Code Type' dialog change the option from 'Automatically determine the type of code to debug' to 'Debug these code types' and choose ONLY the options for you project. For me this was 'Managed (v2.0, v1.1, v1.0)'. Click OK. Then click Cancel in the 'Attach to Process' dialog.
At this point I'm now able to do F5 Debugging.
I hope this helps!

For what it is worth I had this problem this morning out of nowhere. In my case I am converting a database into webpages and one of the folders of one of the projects in my solution now has over 200 thousand html web pages. As soon as I one off'd my solution and removed the project with the giant folder debugging worked again.
This is not unlike what happens when performing a global search and vs 2010 tries to search a folder with an enormous # of files.

Visual Studio C# ASP .NET Web Form Designer Error

Ok, so I start a new project in Visual Studio (currently updated to update 3) and choose ASP.NET Web Application (.NET Framework).
Then I choose the Empty template and to add the folders and core references for Web Forms.
Ok, great, so I add a webform to the project and then find there's a problem:
Design view or even Split view is not available for the new aspx page.
Pressing the buttons 'Design' or 'Split' do nothing and only the source is seen, which also becomes uneditable.
Now I have seen this issue before and searched and searched for an answer. But the only solution was a complete reinstall - this means a few GB download and then hours of the install program doing whatever it does (it is the slowest install for anything on any platform).
This issue seems to occur randomly, and once it occurs, it seems to be permanent, short of a complete reinstall of VS.
Is this a fault in Visual Studio that will never be fixed?
Does someone actually know how to fix this other than a complete reinstall?
Please do not suggest to try 'Open With' on the aspx file - yes I have tried every option and the original default is the correct one.
Answers from the Microsoft forum are about as helpful as giving wheels to a tomato, such as here. It has even been highlighted for Visual Studio 2008 here. Someone seems to have tried to raise the issue last year here.

Website running .NET 3.5 cannot use feature not part of ISO-2 specs

I am getting this error a lot:
Feature '{insert feature here}' cannot be used because it is not part of the
ISO-2 C# language specification
I am working on a .NET 3.5 website that I've worked on on and off for about two years. I've never seen this error before my most recent around of updates. I'm using a decent amount of LINQ coding throughout and I get these errors related to much of the LINQ code. Based on what I've read it seems like even though I'm using .NET 3.5, for some reason it thinks I'm using 2.0. But I can't find anything that says how to fix it.
One example of a problem is that if I try to add a new item to the App_Code directory, I do not get the option to add a LINQ to SQL dbml file.
If anyone can shed some light on how exactly I would fix this, I would much appreciate it.
I was unable to locate an "Advanced" option under the build tab. I have a feeling it is probably because it is a web app. I looked through the web.config and found 2 parts that may be important. Most things referenced 3.5.0.0 or v3.5. The settings are consistent with older backups of the web.config from when there were no errors. By the way, only intellisense and things within VS2010 are giving me problems. The website is running error free.
I have completed a total uninstall and re-install of VS2010 and I'm still having the same issue. I fired up my old install of VS2008 and I am NOT having this issue there. However, I would MUCH prefer to use VS2010 on this project.
I opened the website in VS2010 on my work computer, and there are no errors reported. This is making me think that there is something on my laptop that is causing the problem. As I noted above, I completely reinstalled Visual Studio 2010 and I am still having the problem. What does this leave? I have only one extension installed in VS, and it's the same one at work and on my laptop. Also, I did not reinstall the extension after reinstalling VS, and the problem persists.
Both PC's run Win7 Ultimate. Have VS2008 and VS2010 installed. VS2010 has the same extension installed on both. On my laptop I have the full version of SQL Server 2008 installed, but only the Management Studio on my desktop (we have a server in the office). Would SS2008 have anything to do with it?
Go to your project properties, the Build tab, Advanced - that should allow you to set which version of C# you want to use. It should default to the latest version supported by the version of Visual Studio you're using, but it sounds like at some point you've switched it to ISO-2.
(That's certainly true for Windows projects and class libraries - there may be a different location in a web app. In particular, have a look in Web.config.)
If this has only started happening recently, I'd have a look through your source control history at changes to any configuration files. Also try creating a new project of the same type, and see if that has the same problem.
Jon Skeet's answer is mostly correct. The location for the update is in the "Property Pages" which I got to by right-clicking on the name of the website, clicking Property Pages, the Build item, then target framework.
The extension I use, Solution Navigator, has it's own heading for the solution. Right-clicking on it DOES NOT give me the Property Pages option. By chance I right clicked on the title of the website under the solution heading and was presented with the Property Pages option. In there was the Build tab which contained the target framework option.
Once I finally found the target framework option, it was indeed set to .NET 2.0 for some reason. I changed it to 3.5, reloaded the solution, and now it works great.
Thanks a million Jon for your help and time working with me!!

VS2010 Crashes closing specific project

I'm working on a "Website Project" (as opposed to an ASP.NET Web Application) which we received from another company as part of an acquisition.
In general it works fine, however every time I close the project ("File" -> "Close Project" or just "File" -> "Exit"), the IDE crashes.
If I create a new project this doesn't happen, and it doesn't happen for any other project/solution file I have handy.
The other information I have that might be useful is that this project may have stared out as a VS2008 project, and previously it was under Microsoft source control (it's under Subversion now).
This is a reported VS bug from 2008 to vs 2010.
Here is a direct link: http://connectppe.microsoft.com/VisualStudio/feedback/details/577369/vs2010-crashes-when-closing-project-or-ide
Ya I had a project like that once. Chances are there are 1001 possible reasons. Just start a new website project, copy over your source files, and cross your fingers. It's not worth trying to figure it out, since it works fine otherwise.

Don't see Clean solution option in Visual Studio

For one of the solutions, I don't see the Clean Solution option neither in the context menu when I right click on the solution name in the Solution Explorer nor in the Build menu. When I make any changes to the project and debug, VS never hits the break point and I get the "The breakpoint will not currently be hit. The source code is different from the original version." message. My understanding is that I need to clean the solution.
For other solutions, I do see the Clean solution and I don't have the same issue.
If you are using website project then their wont be clean solution option,it's available only with web application projects.
Finally had to create a brand new solution and add the projects from the older solution to the newly created one. Not sure what the problem was, but this helped.
I also faced the similar problem recently and this is what I came to.
I guess you are running an older code version than the one you want to debug on. Rebuild the project(s), paying attention to dependencies. Use the "Rebuild" feature.
If it's a Web application project, just clean it yourself by nuking all DLLs in the bin. Then rebuild. I assume it builds without errors?
If you're running a web site, as apposed to a web application project, you probably don't have an actual solution, or even a project file.
For a web site, you need to rebuild the website (from the build menu), or manually delete all of the dlls to accomplish the same thing.
Edit:
How are you debugging? Are you using Cassini (the built in visual studio debugger), or attaching to an IIS process?
I would also try this:
Go to C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files and delete the folder that has the same name as your website.
I had the same problem. Visual Studio was building my old code with debug. I opened a new instance of Visual Studio and opened my solution with it and it now works fine. No idea what happened.
You can also clean using devenv /clean SolnConfigName SolutionName in the command line environment.
Here is the reference: http://msdn.microsoft.com/en-us/vstudio/aa718635.aspx
For a website solution, just clean your web browser history and the Cache there.

Why does Visual Studio lag when working with some ASP.NET sites?

I am working with an ASP.NET website that is currently being referenced by IIS. When I open .aspx files for editing, the pages seem to hang randomly - has anyone else experienced this? Is there a known cause (and solution)?
Thanks
I had the exact same problem but maybe another cause.
If you use GIT in your visual studio, turn of "Show current branch in Visual Studio".
All of my lag went away in an instant.
Something that seems to exacerbate this problem is non-compliant markup, but it can often happen with control libraries and also happens occasionally with the vanilla controls for no apparent reason.
You might want to change the default to "source view" rather than "design view". You can do this, in:
Tools >> Options >> Html Designer >> Start pages in
