Cannot install for Xamarin.Android

[clairernovotny]

What version of VS and what version of NuGet do you have installed there? xunit.runner.utility contains a PCL 259 and is compatible with Xamarin.Android.

VS2013, NuGet 2.8.6

[clairernovotny]

Hmm...what version of Xamarin do you have installed? Do you have VS 2013 Update 5 installed?

I have the Update 5 for VS 2013 and the latest stable Xamarin installed. The Extensions and Updates shows NuGet as 2.8.60723.765.

I went to file -> new blank Android application, then in the NuGet UI, added xunit.runner.devices. It all installed ok.

Thanks for testing. It's also VS2013 Update 5 here.

I will try from the GUI

[304NotModified]

Same steps (new blank app) and also NuGet 2.8.60723.765

I will try now with update of Xamarin.

Did the Xamarin update resolve this?

Sorry, has a small holiday.

No it did not. I tried reinstalling xunit, and also failed with the same error:

install-package : Could not install package 'xunit.extensibility.core 2.1.0'. You are trying to install this package into a project that targets 'MonoAndroid,Version=v5.0', but the package does not contain any assembly references or content files that are com
patible with that framework. For more information, contact the package author.

It seems to be working in VS2015, but I really like to have it working in VS2013

[clairernovotny]

It's probably a NuGet bug....just curious why VS 2013 though if 2015 work?

[bradwilson]

curious why VS 2013 though if 2015 work?

Because VS 2013 uses NuGet 2.x, and 2015 uses NuGet 3.x.

[clairernovotny]

No, I get that. I'm curious as to why the need to continue using VS 2013 here. There definitely seems to be a bug with NuGet's compatible frameworks list that has since been fixed.

Well I don't like to force the community to use vs2015 and also I have seen enough issues in vs2015 already (crashes VS, crashes compiler, performance issues) .

I have used every version of visual studio since VS 2003, and my experience is that every new version has (big) issues at the start. So I'm a bit defense with upgrading.

Xamarin has big issue about update package in visual studio. If I update package in nuget manager It always have problem about remove and update System.Runtime or System.Runtime.InteropServices 4.0.0.
