Description Alexis Comte 2016-08-05 11:39:11 UTC
Unable to resolve dependencies. 'Xamarin.Android.Support.v7.AppCompat' is not compatible with 'Xamarin.Forms constraint: Xamarin.Android.Support.v7.AppCompat (= 23.3.0)'.

I have installed Xamarin Forms and it seems it is incompatible with Xamarin.Android.Support.v7.AppCompat

this is very strange

I am a little new to Visual studio universe with nuget package , so it was quite confusing for me to find why this was not working at all

When I was trying to update the NuGet Packages for one of my Xamarin project, I got the error same as this..

Please check Compile framework and target framework of your android app.. and update your NuGet packages according to the properties of your android app. Below link describes how did I fix the issue.

Thank you for taking the time to submit this report. You would need to install the specific version of the Xamarin.Android.Support.* libraries that match the constraint. In this, version 23.3.0 and not You can do this with the NuGet package manager. There is a drop-down to select the version you want to install. If you are trying to "update" the packages, that won't work since that version of Forms requires only version 23.3.0. 

For those that may be hitting similar issues more recently, please note that if you update to version 2.3.3+ of Xamarin.Forms, AND you set your Android project to Target Android API 24+, you can use newer versions of the support libraries.
