Autocomplete intellisense not working in Visual Studio 2010 Ultimate RC

Question

Using C# in Visual Studio 2010 Ultimate RC intellisense only works when I use crtl-space, When typing I do not get autocomplete and after typing "." after a method or variable I do not get a drop down list of suggestions. My settings  in Tools --> Options --> TextEditor -C# match exactly my settings in VS 2008 where intellisense works as expected.

What can I do to correct this?

Thanks.

Answer 1

Hi SR1995,

I am moving this thread from Base "Visual Studio Setup and Installation" forum to the "Visual Studio 2010 Setup and Installation" forum, since the issue is related to VS2010. There are more experts in the "Visual Studio 2010 Setup and Installation" forum.

Thanks

Best regards,

Hello,

As far as I researched, there is a known issue about the VS 2010 Intellisense. The issue can cause Intellisense dismissed or VS crashed.

You can find more information from Scott Gu's blog,
http://weblogs.asp.net/scottgu/archive/2010/02/15/patch-for-vs-2010-rc-intellisense-crash-issue-now-available.aspx
, as well as a hotfix for the issue.

If you still encounter this, I suggest you raise a feedback in connect site to report it.

Answer 4

The hotfix did not correct my Intellisense problem. The situation remains as in my post of 2/17.

Thank you.

Answer 5

Hello SR1995,

I cannot reproduce the issue. Then could you please try to reset your Visual Studio by,

1. Make sure no devenv.exe is running.
2. Try running from Start->Run:
   devenv /resetuserdata (This causes a new devenv process run to do the resetting job)
3. Open task manager and check that the devenv process finishes (this takes a couple of minutes)


If this still does not resolve the issue, I suggest you submit this issue via connect site.

Hello.

I had the same problem - its not a bug and misunderstod above:

You and I accidentally switched into low-impact IntelliSense mode by pressing Ctrl+Alt+Space. Just hit Ctrl+Alt+Space to go back to the thing you want.

(I suppose you are not having this problem any more, but other peope might come by ;) )

More about this problem here:

Answer 7

I was having the same problem this morning.  The Ctrl+Alt+Space suggestion didn't work in my case but running devenv with the /resetuserdata argument did.  Thanks for the help.

Answer 8

Hi Anders,

 

Thank you very much for the info you shared.

Ctrl+Alt+Space fixed the IntelliSense in my case.

 

Regards,

Deepak

Answer 9

none of the above solved my problem. I found out that in the web.config file, the system.web > pages > controls had several dlls that were no longer being referenced by the project (but still had 'asp' prefixes):

When I removed the top 4 Microsoft.Web.Preview tags (carried over from several versions of code and no longer used or referenced), it suddenly worked.

 

 

    <pages theme="DefaultTheme">
      <controls>
        <add tagPrefix="asp" namespace="Microsoft.Web.Preview.UI" assembly="Microsoft.Web.Preview" />
        <add tagPrefix="asp" namespace="Microsoft.Web.Preview.UI.Controls" assembly="Microsoft.Web.Preview" />
        <add tagPrefix="asp" namespace="Microsoft.Web.Preview.Search" assembly="Microsoft.Web.Preview" />
        <add tagPrefix="asp" namespace="Microsoft.Web.Preview.Diagnostics" assembly="Microsoft.Web.Preview" />
        <add tagPrefix="asp" namespace="System.Web.UI" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
        <add tagPrefix="asp" namespace="System.Web.UI.WebControls" assembly="System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
        <add tagPrefix="ajaxToolkit" namespace="AjaxControlToolkit" assembly="AjaxControlToolkit" />
      </controls>
    </pages>

Answer 10

Resetting Visual Studio as Ji.Zhou said... now it is working.
So Reset by "devenv /resetuserdata"

Answer 11

This solved my problem as well, so I'd like to second the "proposed as answer".

Answer 12

Resolved my issue by run "devenv /resetuserdata" command

Answer 13

Anders,

Ctrl-Alt-Space only turns drop-down box "automatic selection" on or off. You still get the drop down box whether this is on or off.

BTW - the problem causing my missing intellisense was me having turned off compilation for the class I was working in - der!

Answer 14

I had the same problem, I tried different methods suggested in different discussion forms, but none worked fine in my case. But in between I found the intellisense is not working for a single solution and finally found the compilation error makes the intellisense not working. So in order to reach your problem you may go through these steps

1. Compile the entire solution and correct the compilation error. If it is not working do the following steps too
2. devenv.exe /ResetSettings
3. devenv /resetuserdata
4. Goto settings and check the following setting are there

Answer 15

Thanks it works for me :)

Answer 16

I had a similar problem, somehow one of my files dropped out of the project, so "String." would bring up intellisense, but "this." would not. Adding the file to the project again through Solution Explorer fixed it.

Answer 17

I had the same problem, but my VS 2010 was not showing the CSS classes with intellisense. This tip resolved my problem. Thank you very much.

Worked for me as well, had to do the deveenv /resetuserdata.  The Ctrl+Alt+Space didn't work so did the command line solution.

Thanks :)

Answer 23

I had this issue when I accidentally opened my site in VS from the folder containing the wwwroot (rather than opening the wwwroot directly).  In my case, I noticed that the page declaration was indicating an error. 

Answer 24

This works for me.

Thanks a lot.
