I saw multiples post/question about it on StackOverflow but about ASP.NET
I am getting the following:
/Library/Frameworks/Mono.framework/External/xbuild/Xamarin/Android/Xamarin.Android.Common.targets(2,2): Error: Exception while loading assemblies: System.IO.FileNotFoundException: Could not load assembly 'System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. Perhaps it doesn't exist in the Mono for Android profile?

Now the interesting point is that my project isn't an ASP.NET project att all x) So first, what the hell?
I did this video: https://channel9.msdn.com/Shows/XamarinShow/Snack-Pack-15-Upgrading-to-XamarinForms-to-NET-Standard
I upgrated the .NET Standard project to 2.0. My Android target is 8.0 and the compiler as well. I tried to upgrade all of my Xamarin.Android.* packages but no success...
Any idea?
Thanks

Indeed the assembly Xamarin.Forms.Xaml is not signed (Strong name = false)

I can see that it's probably related to the package Microsoft.Azure.Mobile.Client but not sure what I would have to do to resolve it (I'm quite new to Xamarin so not sure what to do with this information).
My minSdkVersion is 21.
Thanks
It looks like the guys of Microsoft.Azure.Mobile.Client package have problems with Android.Support.CustomTabs library. Please refer to the posted issues on github: Issue 364 and Issue 361. It looks like Microsoft.Azure.Mobile.Client version 4.0.0 can be built against Android.Support.CustomTabs version 25.3.1, but Microsoft.Azure.Mobile.Client version 4.0.1 can be built against Android.Support.CustomTabs version 23.3.0.
In my case downgrading nuget package Microsoft.Azure.Mobile.Client from version 4.0.1 to version 4.0.0 helped to build and link my project.

I am trying to build My Xamarin.Adroid project for release. But i keep getting this error. General consensus on the web is that that my Targeting framework and minimum SDK versions have to be so and so, but I have tried them all to no avail.
Both those SDK's are installed on my machine, I also have the latest preview of Xamarin forms added.
Nothing I am trying seems to work. Any help regarding this would be greatly appreciated.
Thank you in advance.
Looks like the method Android.Widget.TextView::SetTextAppearance(System.Int32) first appeared in API23: M. You'll need to change your compile and/or target versions to point to M.
After updated xamarin version i start getting thi error. Clean project first then build it again. fixed for me. Rebuild not working.
