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.

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.

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.

What an awsome extension. Fantastic.

by Abel Gaxiola | December 17 2014

I like the extension and will give it five stars if given the ability to turn it off by a combination of keystrokes. Reason: don't need it for everything; it kind of gets in the way when doing simple things;

What should I say? I love this extension.

Excelente integração, sem crashs.

Good. A few suggestions:

1. Provide an option to switch back to the default intellisense experience.
2. Improve fonts & colors for codes in the sample browser.

by MikeSchellenberger | September 28 2014

Found this to be a very annoying feature so I disabled it, I'm fine with doing my own search when I need to...not everytime I do something in VS. I later discovered that even disabled it caused VS to constantly use 13% processor.

Hello Mike
The plugin itself does not do any heavy work. One possible reason for the higher CPU usage is the local index. The plugin uses Windows Search Service to index your local code projects for local code search. Your Windows Search Service (not Visual Studio) may occupy a higher CPU usage for a while (before it finishes indexing the source code). We really hope to help you with the issue. Would you mind emailing us (, and we can help through email.

When pressing Ctrl+Space to show the list of suggestions (when it is not visible), Visual Studio crashes.

(@Language Experience Team) Issue is now resolved. I haven't seen any problems after installing the latest update.
Thank you for this great extension.

  • 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. 
  • Opens search in wrong browser
    2 Posts | Last post March 17, 2015
    • Hi, I have found that the Bing Contextual Search ALWAYS opens the results in Google Chrome, even though my default browser is IE 11 and .HTML files are associated with IE.
      Any chance this can be fixed so that it responds to system defaults (IE, whatever Windows is configured to use)?
    • I have the same problem.  In my case it always opens Opera.  I'm guessing it's opening the last browser installed on the system, maybe.

    • add option to enable/disable IntelliSense experience
    • Hello Ashish
      The setting was just added to the new version of Developer Assistant. Please check out our release note:
  • Useless
    6 Posts | Last post January 26, 2015
    • Still not working if ReSharper is installed :( None of the suggested workarounds works either.
      Fix this ASAP please.
    • Hi Georgi
      Both Resharper and Bing Developer Assistant are customizing the Intellisense UI to provide more functions.  You have to choose one to enable.  To disable Resharper's Intellisense window and use Bing Developer Assistant's, please follow these steps:
      1. Go to Tools / Options menu item.
      2. Expand the ReSharper in the Options list, and click 'Options...'
      3. Expand the IntelliSense node in the Options window. Under 'General', choose 'Visual Studio'.  By default, it is 'Resharper'. 
      4. Save the changes. 
      Now, if you type some code again in the code editor, you will see the new intellisense API search experience provided by Bing Developer Assistant. 
    • This doesn't work for me in VS2013. When I follow the instructions above I get no IntelliSense at all.
    • The same is happening for me.  I know get the Bing intellisense feature, but only when hitting CTRL+SPACE.  When I simply type object dot I get nothing.
    • I'm surprised this doesn't work if ReSharper is installed. ReSharper is one of those "must haves" for any serious .NET development.
      Turning off ReSharper features is not appropriate.
    • I had the same problem as you guys have after disabling ReSharper intellisense. But I was able to fix it by going to tools -> options -> text editor -> all languages -> General and changed the auto list members and parameter information to be checked. Now intellisense work as normal again. 
      I still hope that this plugin could work alongside ReSharper without such hacks in the future.
  • bing developer assistant how to change font size
    6 Posts | Last post January 15, 2015
    • bing developer assistant default font size is so smaller!!!!!!!
      how to change font size??????????
    • Hello Lanymy
      In the current release, we do not have the feature to change the font size. However, I think that what you suggested is a great idea.  Do you think that it makes sense to use the VS font size setting (in Tools / Options / Environment / Fonts and Colors) to display the info in BDA? 
    • [VS font size setting (in Tools / Options / Environment / Fonts and Colors)]  it doesn't work for [bing developer assistant default font size]
    • Please check it
    • Hi Lanymy
      Yes, today the setting does not change the font size of Bing Developer Assistant.   I meant to ask if we improve BDA to use the font setting in Tools / Options / Environment / Fonts and Colors, will it work for you?
    • no working
  • Can't type 'return'
    2 Posts | Last post January 08, 2015
    • When I type 'return' (i.e. to return value from function), BDA, only gives me options for AnyReturnReader, MimeReturnReader, NopReturnReader, TextReturnReader and XmlReturnReader and I have to hit 'escape' every time be able to 'leave' return as is, otherwise it fills in AnyReturnReader when I hit space.  Any way to stop this?
    • Scratch that.  Accidentally was in a property method and didn't have get { } wrapping around it.
  • BUG?

    • Hello

  • Code Sample shortend Source URL - Tooltip
    3 Posts | Last post December 04, 2014
    • It would be nice if the complete Url can be shown as a tooltip.
      At the moment the url is shortened so you can't see where it points. This is particularly bad when it's a file path..
    • Thank you for the suggestion!  We will add this improvement soon. 
    • Hello zandis59
      We have just released this improvement.  Now, if you hover your mouse over the URL, you can see the complete URL in tooltip.  Thank you again for the feedback! 
  • The size of IntelliSense bing search window
    4 Posts | Last post December 04, 2014
    • Hi, 
       Does we can change size of the Bing search intelliSense window ?
    • +1
      Also it would be nice to be able to move the window!
    • Thank you for the great suggestion!  Maybe it also makes sense to allow user to pin the code samples? 
    • Hello 亂馬客
      We have just released the feature that allows you to resize the intellisense window.  Please upgrade to the new version.  Thank you again for your feedback. Your suggestion makes a big difference :)
