I encounter a stranger behavior with a Xamarin.Android project in Visual Studio on Windows.
I've created a new Android blank project, and I try ton install the NuGet package "AForge" (a mathematics library), but I get the following error message:
Package AForge 2.2.5 is not compatible with monoandroid81
(MonoAndroid,Version=v8.1).
I've already tried to re create several projects, after having relaunched Visual Studio and the computer, but the problem is still the same.
However, if I do the same thing on Mac, through Visual Studio for Mac, I don't encounter the same problem: the package is well installed.
In add, I can see in the package.config file, that the package il well related to monodroid81:
<?xml version="1.0" encoding="utf-8"?>
<packages>
<package id="AForge" version="2.2.5" targetFramework="monoandroid81" />
</packages>
Would you have any explanation about this issue?
