Intellisense -> Toggle Completion Mode (Grayed out) - c#

What are my options?
I arleady made a topic before asking how to enable Intellisense in Visual C# 2010 Express
I reinstalled Visual C# 2010 Express twice now without any results.
I downloaded QuickSharp fresh install same issue no intellisense.
Maybe something wrong with my computer? Windows XP
I created a new Windows Forms Application here called it test.. and just clicked on Form to get Form_load code and typed System. (dot) (nothing pops out!)
I have reset the settings, this did absolutely nothing.

Xamarin android emulator on Visual Studio 2017 blacked out

So I'm trying my hand at making mobile apps using C# and Xamarin on Visual Studio 2017. What I'm trying to do is test out the system by making a simple application that has two buttons that either increment or decrements a number by 1 when clicked. Nothing fancy. But when I try to run the android emulator, it is just a black screen. Nothing loads. And when I "x" out of the emulator, I get a There were deployment errors. Continue? dialogue box when it's done.
I have searched all over for a solution, and nothing I've tried has worked so far.
Among the things I have tried:
Enabling virtualization in the BIOS settings.
Disabling "Use host GPU" in the AVD.
Change from Debug mode to Release mode.
Ticked "Wipe User Data" from the launch options.
Restarts and rebuilds along with "clean Solution" here and there.
I also tried using the Xamarin Live Player paired with my phone to no avail.
(Also, I have no drawable icon in my drawable folder under resources. Is that anything that's necessary??)
Here's a screenshot of my problem:

I'm using Visual Studio 2017 on Windows 7.
If you have JDK 9 installed you can try uninstalling it.

This fixed the problem for me. I had JDK 9 installed and even if in my Xamarin options I was pointing to JDK 8 folder, it was messing up my deployment.

Default Universal App template causes XAML designer crash

I have VS2015 community and also SDK 10 and tools.
When I open blank universal app , I get this message in visual designer : message
I disable developer mode and reset computer but still I have problem.
Please Help.
Thanks.
I had a similar problem with Visual Studio 2012 when building a WPF application. The build succeeds but the intellicence dosen't work for xaml in this case. I went to Tools->Extentions and Updates and installed Visual studio Update and it started working. Not sure if this helps but please give it a try.

WPF Designer can't load VS2015

I have this error when I try to open a WPF file in the designer even with a new project. Everythings else works perfectly. If I try to compile the project it works nicely as well.
I have tried to uninstall visual studio 2015 and reinstall but nothing changed. On another computer I don't have any problem to open my projects.
Edit : Found this link still not working but not sure about the "Ensure your x86 platform has the correct values to target x86" meaning
It may sound like a silly question, but is Internet Explorer 10 (or later) installed? See https://support.microsoft.com/en-us/kb/2906882. I had different problems to Microsoft's when I uninstalled IE.
Otherwise, you might try to repair your installation. Go to Control Panel -> Programs and Features -> Microsoft Visual Studio and choose Repair.

Visual Studio 2015 Debugger remains active after application is closed

There is an old similar question without answer so I've decided to ask if someone has a hint on this:
I've installed a new Windows 10 Laptop with Visual Studio Enterprise 2015.
After setting all up, I've checked out one of my solution, that is working perfectly on Windows 7 and VS 2013 and I have the problem indicated on the subject.
I start the application, I can debug it or stop the debugger without problems, but if I close the application the application closes but the debugger remains active.
The application is a WPF Windows application, the Shutdown Mode is set to ShutDown when the main window is closed.
Now, I know that maybe Windows 10 is different and Visual Studio 2015 is different, but this is not a normal behavior in my opinion.
if you have any clue, maybe I've lost some new setting?
Thank you in advance
I was able to resolve the issue by doing a simple repair of Visual Studio installation.

Designer view doesn't show up in VS2013

I have recently installed Microsoft Visual Studio 2013 Express for Windows Desktop with Update 4.
The build number is: "12.0.31101.00 Update 4" with .NET Framework build number: "4.5.51641"
I have reboot my computer after the installation and I am using Windows 8.1 x64 with the latest updates also.
When i create a Visual C# => WPF Application project, and i try to hit "View Designer" on the item "MainWindows.xaml" or press "Shift+F7" on the code view the designer does not show up.
I have tried everything, but no designer seems to be in this edition or Visual Studio... No menu even tells the name "Designer" anywhere.
I have used 2010/2012 Express and i always used to have the designer.
Did Microsoft remove the designer from express versions now ? :O
Thanks for your help.
Ok... I just solved my issue.
The ISO i have downloaded was about 2,00 GB, and I noticed it's a little too light to be VS 2013 (even Express).
The ISO I have just downloaded is about 6 GB. Works nicely now!
Download link: www.microsoft.com/en-US/download/details.aspx?id=44914
Click "Download" then check the ISO file.
