Android and iOS Development using C# : Xamarin

Long back when Android was in its initial stages. Android 1.6 sdk was out there and Google trying hard to push developers to develop for it using various competitions I downloaded Donut SDK and IDE.

Those were initial days of my career and I had been using Visual Studio as IDE and Eclipse felt like a Haunted Village when compared to Visual Studio which was like a Metropolitan city.

After that experience Developing for Android went out of Window and I missed the train of New and Rising OS.


But it’s never too late to start developing and if you are like me and have phobia to develop in Eclipse and Java there is good news for you. Download Xamarin and start developing for Android and iOS.

You’ll definitely love the experience and the comfort of good ol C#.

Windows Phone Emulator Error

While trying to run Windows Phone emulator I was facing given error.

The Windows Phone Emulator wasn’t able to create the virtual machine: Something happened while creating a switch: Xde couldn’t find an IPv4 address for the host machine.


Simple Resolution to this problem is:

  • Run Hyper-V Manager as Admin


  • Go to Action > Virtual Switch Manager.


  • Click on “New Network Switch’


  • Select Internal and Create Virtual Switch


  • Give Name of Virtual Switch as “Windows Phone Emulator Internal Switch”


  • Click “OK” and restart your machine.



    After following these steps you should be able to run Windows Phone 8 Emulator without any issue.

    In case it solves/ doesn’t solve your problem mention that in comments.

Recently we tried to import solution on CRM which was recently updated from UR 6 to UR 12.

To resolve this following post from Microsoft discussion forum helped

  1. Stop Async Service in services.msc
  • Run “services.msc”
  • Stop Async Service


  1. Take Microsoft.crm.sdk.proxy.dll from latest sdk
  2. Open Visual studio command line tools (in administrator privileges)


gacutil /i c:sdkbinMicrosoft.crm.sdk.proxy.dll


  1. IIS reset, restart CRM Async Service in services.msc

Try importing the solution


PS: If you are in a farm deployment then Install Microsoft,crm.sdk.proxy.dll in the server running CRM Async Service.

Before installing dll, stop the async service, install dll in gac and restart async service.
