The Intellisense extension don't work correct with "Dark" theme. Could you change this?



by JayChase | August 12 2015

Still getting used to it but I can see the potential. Any guidelines as to how to get a code sample to show up would be handy.

I really like it and used it a lot in Visual Studio 2013.
It will sometimes cause VS 2015-intellisense to hang though... Sadly :(

Loved this feature, used it for the past couple of months... however I had to recently uninstall for the following reason:

Everytime I used System.IO.Path.ChangeExtension visual studio 2013 locked up and eventually crashed. This would happen regardless of the solution and project I would try it on, I then uninstalled the Bing assistant and now it works??
Kind of a weird issue, I will try the updated version and see if its any better...

It is very great. In the future, I want you to also support VisualBasic.

Looks cool in the videos. For some reason mine would open opera rather than IE, my default browser. I uninstalled Opera and now it doesn't do anything at all. Frustrating.

I don't know if the problem is in the developer assistant or in the preview version of Visual Studio 2015, but it locks up VS while trying to search for a code sample. Considering that this happens automatically when typing any code, this is horrible.

It is caused by a known issue in VS2015 Preview. The VS team is trying to fix it before the RTM release.

by LarryDisplayName | February 20 2015

I only rate this poorly because I wasted a bunch of time trying to figure out why the Intellisense wasn't working for my VB project. The part of the documentation that says it only works for C# appears at the end of the documentation - and might as well have been in fine print for people like me who don't always carefully read ALL of the paragraph.

by Zephyl Khiem | January 22 2015

it will great if we would have option extension old and extension new. thanks you

Hello Zephyl
Thank you for your suggestion! The setting is added in last week's new release. Please check out our release note:

by iJacks | January 20 2015

Does it work? Yes.

Does it always ignore my default browser setting and open results in chrome? Yes :(

I simply cannot believe that the code is doing this deliberately (though it clearly is) - in this day and age writing ANYTHING that is browser specific is the greatest sign of a poor developer/development team. It's a real shame as the extension is great, right until it opens Chrome. Please fix this (no excuse for this really is there?) and I will consider this a 5 star essential extension - as it stands I have removed it until a more professional version is made available.

    • It says its offline and so doesn't let me search code samples.
      Do we know what could be the cause?

    • After upgrading to latest version VS2013 caughs an exception when starting.
      Tells me to check AppData\Roaming\Microsoft\VisualStudio\12.0\ActivityLog.xml
      I did not find anything obvious.
      I believe it was from 6.5.0 to 6.5.2.
    • Same error VS2013.
    • I get the same error: System.InvalidOperationException: Duplicate EditorOptionDefinition named ControlClickOpensPeek
      It appears for me when I also have the Productivity Power Tools extension installed. The error appears to show that both the Power Tools and Developer Assistant are both trying to use 'CTRL+Click' event. If I disable 'CTRL+Click Go To Definition' in Productivity Power Tools or disable the Developer Assistant extension the error goes away.
    • I can confirm, disable 'CTRL+Click Go To Definition' in Productivity Power Tools solves the issue (for now).
    • 6.5.3 did not fix the issue. Maarten, thanks for the 'CTRL+Click Go To Definition' temporary fix.
    • We have just released the fix.  Please try the update 6.5.4.  Thank you all for the feedback!
    • I have try it,but still the same.
    • 6.5.5
  • this addon can not work

  • Why Not Supported for C++?

  • Will there EVER be full support for VB?
    1 Posts | Last post September 24, 2015
    • The title says it all.  I can't really complain when 3rd party packages give VB the short shrift, but it seems to be the case with Microsoft as well.  This is version 6.5.4 and VB support is still an after thought at best.  The last post I saw about this said that the team was hard at work trying to bring features to other languages. I wish I could see a little bit of love thrown toward VB.  Is it really to much to ask that for at least one version be shipped that is feature complete with respect to VB?

    • Hi, after installing DA I have some problems with IntelliSense not working at all (probably regarding to previous Resharper Instalation). Problem is I can't disable DA IntelliSense. When I try to switch IntelliSense to "Default VisualStudio IntelliSense" via VS Options/DA/IntelliSense  it freezes whole VisualStudio and restarts it after a while.
      I managed to debug the VS error and it's message is:
      Could not find a part of the path 'C:\Users\[USER]\AppData\Local\DeveloperAssistant\2013\Installed\switchIntell.txt'
  • Does not work on Ultimate?

    • I just download and install. But i do not see "How do I" Intellisense feature in my VS2013. Do i need to change something on VS2013?
    • Hi 
      The 'How do I' feature was moved to the 'Search Code Sample' in the toolbar.  We added the new intellisense experience that shows code samples for APIs (as you posted in  However, thanks to users' feedback, we will move the 'How do I' feature back to the Intellisense in a future release.
    • Hello Yokonn
      The 'How do I' search is added back to the Intellisense in our latest release in March!  Please check it out.
