Logs & screenshot attached.

Intelligence not displayed when trying to change the component or value of the android widget from the designer source.

Xamarin for VS -
XA -
XI -

Steps to reproduce:
1. Create single view Android project.
2. Double click on Main.xaml file to open the designer.
3. Drag button on to the designer.
4. Click on Source tab to open the designer source code.
5. Try to add more values into the button code from source, enter "a" to open the intelligence & observe.

Actual: Intelligence not displayed for the widget value available.

All the property should start with android widget & should displayed in intelligence window.

NOTE: Its working fine with Xamarin studio on MAC machine.

Please find the attached logs & screen shot for more detail.

Ok, it looks look it won't autocomplete the namespace, but once you have "android:" typed in or whatever prefix is being used that it'll autocomplete the rest.

I'll figure out why it is doing that.
Comment 6 Stephen Shaw 2017-03-30 17:58:23 UTC
Jacky, would you be able to go into the obj/Debug/Schemas/*/ and zip up and attach the xsd files. There should be about 4 files.

* -> it'll be some number. Probably 25? It doesn't really matter which number is there though.

We do not control *when* the intellisense popup appears. If you write some text and the popup does not appear because you started typing while the caret was right beside the `/` character then that is normal Visual Studio behaviour and it is correct.

We are only concerned about the contents of the popup when it appears. In this case it looks like it does contain all the correct information when it appears, so this bug looks like it's validated-resolved.

If you think the bug still exists can you describe what the problem is?
Comment 12 Tanmay Bhattacharjee 2017-05-19 09:13:01 UTC
Hi Alan,

Issue here is intellisense only work when user pass command as ctrl+space without any character written.

When user write any latter say "a", intellisense not working & doesn't show the recomadations which is perfectly fine with VSFM.

I also crosschecked with Android studio, its working fine.

Expected: intellisense should work with blank or some latter entered.

Comment 13 Stephen Shaw 2017-05-23 17:57:37 UTC
@Tammay unfortunately, I believe this is how it works in Visual Studio (for Windows). As far as I can tell this is because there are several namespaces. I don't know if it is because as soon as you type a character it views it as an invalid namespace? With it being a blank line everything is an option. If you type in "android:", "app:", "tools:", etc it'll provide a completion list again however without the namespace included.

Part of the reason you see this work in things like Visual Studio for Mac and Android Studio is because they do not use XSD files for their intellisense or validation support. With Visual Studio we are generating and regenerating the XSD files on the fly because of the dynamic nature of android layouts (ie, changes to +ids, strings, colors, other layouts, libraries and their resources, etc).

The hope for the future is a much better system, but for now we have to use XSD.

Marking it as Resolved because this is how the system works in VS. :(
Comment 14 Jacky Waswani 2017-05-24 11:06:53 UTC
As per Comment 13 , Intelligence only works with ctrl+space on blank line.
Also it works in case of user types  "android:", "app:", "tools:", etc 

As this is expected for Visual Studio, hence marking this bug as Verified.
