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.

I would like to try this extension, but it seems the installer is broken. It says that agreement is missing...

The package does not contain the software license agreement and won't install. If you install through Visual Studio Extensions it will work.

Installer seems to be broken, I get the following error:

Installation Failed
(blah blah)
The package does not contain the software license agreement that is specified in the extension manifest (en/en\Eula.rtf).

Cool extension, thanks for opportunity to search snippets faster!

by Andreas Pollak | August 29 2014

I found the old version better (in terms of results and UI).
I cant find a suitable result in tne new version for my test search
"parse xmlData as xml" where xmlData is a String variable. Originally
this returned a snippet with "XElement.Parse" which was very useful.

I support an additional approach of an extra page, but I would still
prefer to browse snippets in the preview.

I also would prefer a quick way to navigate to the new Codesamples Tool Windows aka ShortCut :-)

One of the best add-ons ever!

by Peter DC | August 26 2014

I find it really helpful and am experiencing less red squigly lines as a result.
As the product ages so more and better code samples should become available.

The response from the devs to fix and improve is really great, can't really ask for more.

Still in beta, maybe it's missing some file. Getting infinite message box showing:

No exports were found that match the constraint:

It would have been better if would have option of switching off the online search(i.e user have a option to switch on/off the online search).

Language Experience Team August 25 2014

Thank you for your wonderful suggestion! May I ask in what circumstance would you want to manually turn off the offline search? Please feel free to email us and we can discuss offline.

Excellent app! It helps me a lot when I'm coding.

by sqlguy | August 22 2014

Will not find anything. Useless!

Language Experience Team August 22 2014

Hello. Would you mind emailing us your query? We will check why the plugin does not find code samples for you.

  • Code Sample shortend Source URL - Tooltip
    1 Posts | Last post September 11, 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..
  • The size of IntelliSense bing search window
    2 Posts | Last post September 11, 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!
  • Useless

    • 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.
  • visual basic
    2 Posts | Last post September 02, 2014
    • just confirming that I believe this is not avail for visual basic vspro 2013..?
      and not related to fact that I have keyboard set up as vb6 or some step I missing.
      Thanks.. :)
    • judas.. I gotta read closer:
      " new IntelliSense experience is only available to C#, ..."
  • Fix intellisense autoselect at start of lambda expression
    4 Posts | Last post September 01, 2014
    • When I writing lambda expression like this:
      var dictValues = context.Where(dv
      at this point when I push space, your extension autoselects something in intellisense popup and replaces my variable 'dv' with whatever it selects in popup window. That's very annoying. Please fix.
    • Thank you for reporting the issue to us! This is a quick note that we are investigating the problem. 
    • Hello Soviet
      We just released a fix for the issue.  Would you try installing the update and let me know if it works for you now?

  • Visual studio crashes a lot
    5 Posts | Last post August 28, 2014
    • Visual Studio crashes when intellisense tries to popup, got the following exception:
      System.NullReferenceException was unhandled
      Message: An unhandled exception of type 'System.NullReferenceException' occurred in Microsoft.OneCode.IntellisensePresenter.dll

    • Hello Tom
      Thank you for reporting the issue!Does it happen when you press Ctrl+Space?  If so, this is a known issue, and we plan to release a fix soon next week.  As soon as the fix is released, I will inform you in this thread.
      If it does not happen when you press Ctrl+Space, would you please share the repro steps?  It will be very helpful for us to diagnose the problem. 
    • Hello
      We have just released the fix of the ctrl+sapce problem.  Could you install the update and let me know how it works for you?  Thank you again for reporting this issue!
    • That seems to fix the problem. Was indeed the Ctrl+space problem, thanks for the fix!
  • Not working behind a corporate fire wall.
    3 Posts | Last post August 27, 2014
    • I tried the exact example from the demo video but the query "read file line by line" returned "No code snippets found".
      Note that I'm behind a corporate fire wall.
      In VS 2012, I had to add the following to devenv.exe.config before it was able to access the online gallery and product updates.
              <proxy proxyaddress="http://<our proxy>:<our port>"/>
                  <ipv6 enabled="true"/>
                  <servicePointManager expect100Continue="false" />
      This is no longer necessary with VS 2013, but could it be that the Bing code search requires access to some specific ports or uses a hard-coded-non-proxy-internet-access?
    • Exactly what i experience!
    • This is also happening to me. However, I've set the default proxy, AND I've set the proxy settings in the Dev Assistant options.

  • Getting Bad Results
    1 Posts | Last post August 27, 2014
    • I installed the extension and tried to use it with a simple example where I was using (Winforms) Timer and the search results where showing crazy debugger attributes.
      I entered: var timer = new Timer() { I
      I got the Intellisense for Interval which is what I wanted but the following search results showed up:
      [assembly: DebuggerDisplay(@"\{MinExtra = {MinExtra} MinSize = {MinSize}}", Target = typeof(WinForms::Splitter))]
      [assembly: DebuggerDisplay(@"\{Text = {Text}}", Target = typeof(WinForms::TextBox))]
      [assembly: DebuggerDisplay(@"\{Interval = {m_msec}}", Target = typeof(WinForms::Timer))]
      [assembly: DebuggerDisplay(@"\{{Value} Min = {Minimum} Max = {Maximum}}", Target = typeof(WinForms::TrackBar))]
      [assembly: DebuggerDisplay(@"\{Text = {m_strText}}", Target = typeof(WinForms::TreeNode))]
  • Ctrl-Space crashes Visual Studio
    4 Posts | Last post August 26, 2014
    • I'm used to complete the function names in the C# editor with Ctrl-Space, but when this extension is active, on Ctrl-Space Visual Studio crashes.

  • Ctrl+Space bug
    7 Posts | Last post August 26, 2014
    • Hi,
      let's say you write this code:
      class Test: IEnumerable
      and your cursor is on the end of IEnumerable, when you hit CTRL+Space VS blows away :)
    • Hello Tomek
      Thank you for reporting the issue!! We are looking into the problem with top priority.  We should be able to fix it soon.  Please keep using the plugin and share your suggestion with us at

      I have the same problem when I use CTRL+Space. I'm waiting for solution.
    • Hope this will get fixed soon because currently this makes the extension unusable :(
    • We will release the fix in just a few hours! :)
