Xamarin Essentials和Xamarin Forms包冲突

Question

当我尝试将Xamarin.Forms & Xamarin.Essentials添加到我的安卓项目中时，我得到了这个-

Resolving conflicts for MonoAndroid,Version=v8.1...
NU1107: Version conflict detected for Xamarin.Android.Support.Compat. 
Reference the package directly from the project to resolve this issue. 
abc.android -> Xamarin.Essentials 0.11.0-preview -> Xamarin.Android.Support.CustomTabs 27.0.2.1 -> Xamarin.Android.Support.Compat (= 27.0.2.1) 
abc.android -> Xamarin.Forms 3.4.0.1008975 -> Xamarin.Android.Support.v4 27.0.2 -> Xamarin.Android.Support.Compat (= 27.0.2).

看起来他们都想使用27.0.2.1对27.0.2的Xamarin.Android.Support.v4。

有人能解释一下我是如何解决这个冲突的吗？我不确定直接引用包是什么意思？

我可以在我的csproj中添加一些东西吗？

我从Redth那里找到了一篇非常好的文章-

https://redth.codes/how-to-fix-the-dreaded-version-conflict-nuget-error-in-your-xamarin-android-projects/

我加上了-

<PackageReference Include="Xamarin.Android.Support.Compat" Version="27.0.2.1" />        
<PackageReference Include="Xamarin.Android.Support.Core.Utils" Version="27.0.2.1" />        
<PackageReference Include="Xamarin.Android.Support.Annotations" Version="27.0.2.1" />       

它安装了Essentials，但我仍然收到这些警告-

然而，我认为我可以在Redths解决方案中看到这些类型的错误，所以我想我会假设我们现在就可以开始了。
