Installed service pack 1, Razor intellisense is now broken, and pasting into a .cshtml file hangs the IDE for several seconds (10+).

Thanks Sean and Hal for the confirmation. Will mark this bug as closed.

Yep, worked. Had the same problem uninstalling ASP.NET Web Pages, but everything appears to be 100% now. Could have sworn my PC had RTM; but clearly a PEBKAC problem ;-)

Yes - turns out I had RC installed as well. The solution you provided worked well (although I did run into a problem uninstalling RC and had to follow these instructions to get ASP.NET Web Pages uninstalled: http://blog.williamhilsum.com/2011/03/error-0x80070643-installing-aspnet-mvc.html?showComment=1300730301942#c5917003648915633578 )

Thanks for the help.

Best regards,

Hi Hal,
Can you check the System.web.mvc.dll version. Do you have MVC3 RC installed on the box? If yes can you please follow the prev post to uninstall MVC 3 RC and install MVC3 RTM.
If this doesn't fix your problem, can you please email me the logs at deepakv at microsoft dot com
Log files can be found in %temp% directory. Please share the log files that contains "mvc3" and "KB2483190"

Thanks Sean for the details. From the version of System.web.MVC.dll it looks like you have MVC3 RC installed. Can you please uninstall MVC3 RC by following Drew Miller's blog here http://drew-prog.blogspot.com/2010/11/how-to-uninstall-microsoft-aspnet-mvc-3.html

After that you can install MVC3 RTM from this link http://www.microsoft.com/downloads/en/details.aspx?FamilyID=d2928bc1-f48c-4e95-a064-2a455a22c8f6&displaylang=en

Please let me know how it goes.

can anyone offer any guidance on whether or not an SP1 uninstall will break Visual Studio to the point that I can't open projects or reinstall SP1? I tried a reapply (of SP1) from the control panel and it didn't solve the problem, but was going to uninstall and received a nag screen stating something similar.

I really don't want to do a complete VS install because of a pressing deadline.

Thanks. Hal

Just to update this issue - I've uninstalled all plugins and extensions in VS and disabled Resharper. I then reinstalled SP1 using the Web PI.

Same behavior, no change.
Posted by Hal Lesesne on 3/18/2011 at 11:28 AM
In addition to pasting delays (also 10+ seconds), I am getting a keypress delay as well.
Posted by Hal Lesesne on 3/18/2011 at 7:56 AM
Exact same problem. Post SP1 install.

Windows 7
Reinstalled MVC 3 - no change.

1. AFAIK it's STM. IN Help|About it says "Version 10.0.40219.1 SP1Rel"
2. Yes. MVC3 RTM AFAIK. File Version for System.Web.Mvc.dll is "3.0.11029.0"
3. VS 2010 -> MVC 3 -> VS2010 SP1. Should I try reapply it?
4. Windows 7
5. x64
6. No colorization/intellisense on a new file. Note that HTML intellisense & colorization works, but not Razor. Screenshot attached of new file.
7. Anything with Razor syntax in it, e.g. "@Html.ValidationMessageFor(x => x.Description)", but not "<td></td>"
8. No matching files from "C:\Windows\Temp", is there anywhere else I must look?

Hi Sean,

Thanks for reporting the issue. It would be great if you can please give us some more details to help us repro the issue in our labs

1. Are you using VS 2010 SP1 RTM or Beta?
2. Do you have MVC 3 installed on your box? Is the version of MVC3 beta/RC/RTM?
3. Can you please let us know the order of installation of VS 2010 SP and MVC 3?
4. OS version
5. x86/x64
6. Are you able to repro this issue only when you copy/paste or does it repro when you create a new cshtml file and start typing (i.e. not intellisense colorization etc comes up)?
7. Can you share the code snippet that breaks Razor on copy paste?
7. Can you please share log files from your temp directory. Please share the log files that contains "mvc3" and "KB2483190"
