Visual studio and Xamarin studio unable to stop building Xamarin crossplatform project

I'm trying to create a Xamarin crossplatform project on visual studio 2015 but it stuck in showing "creating project..." dialog have to force close Visual studio to stop it, so I tried to create a crossplatform project on Xamarin studio instead and my project created successfully but when i try to build the project it get stuck in "building project( debug)" and also can stop it only by force close Xamarin studio.
Any help?
You must have a very slow network connection to the Xamarin servers, so you have to find a way to fix the Android SDK installation. I have some details and you need to carefully change the version numbers based on Xamarin latest release,

Xamarin iOS in Visual Studio is requested to be installed despite the fact that it already has been

All of our Xamarin devs (4 on the team) have started to experience the same error while opening Xamarin.Forms iOS-specific project in Visual Studio 2015. The project fails to load with an error dialog like this:
Clicking install will trigger the installer that will:
but then, since obviously Xamarin iOS is installed, will say that nothing new is there to install:

Visual studio not recognizing Xamarin.Forms project structure/syntax

I am new to Xamarin and downloaded a few sample Xamarin.Forms projects such as this to learn. However, every project I downloaded and opened is full of errors like the one shown in this screenshot. My problem is that although my Visual Studio 2013 displays a ton of errors and warning, I can still run these projects just fine on the emulators (I tried both android and windows phone).
Is there some way to fix my visual studio so that syntax/compiler error messages won't show up?
