Xamarin-无法加载程序集'PCLStorage.Abstractions [英] Xamarin - Could not load assembly 'PCLStorage.Abstractions

问题描述

在将FlurlHttp Nuget软件包添加到我的PCL项目中之后，由于程序集加载错误，我的应用将不再部署到我的模拟器中

After adding the FlurlHttp Nuget package to my PCL project my app will no longer deploy to my emulator due to an assembly loading error

加载程序集时出现错误异常:System.IO.FileNotFoundException:无法加载程序集'PCLStorage.Abstractions，版本= 1.0.0.0，区域性=中性，PublicKeyToken = 286fe515a2c35b64'.也许在Mono for Android配置文件中不存在? 文件名:"PCLStorage.Abstractions.dll" 在Xamarin.Android.Tuner.DirectoryAssemblyResolver.Resolve(AssemblyNameReference参考，ReaderParameters参数) 在 Xamarin.Android.Tasks.ResolveAssemblies.AddAssemblyReferences(ICollection 1 assemblies, AssemblyDefinition assembly, Boolean topLevel) at Xamarin.Android.Tasks.ResolveAssemblies.AddAssemblyReferences(ICollection 1程序集，AssemblyDefinition程序集，布尔值topLevel) 在Xamarin.Android.Tasks.ResolveAssemblies.AddAssemblyReferences(ICollection`1程序集，AssemblyDefinition程序集，布尔型TopLevel) 在Xamarin.Android.Tasks.ResolveAssemblies.Execute()InfoSupport.AV.MobileClient.Droid C:\ Program Files(x86)\ MSBuild \ Xamarin \ Android \ Xamarin.Android.Common.targets 1347

在将Microsoft.Build.Async (1.0.168)，Microsoft.Bcl.Build(1.0.21)，Microsoft.Net.Http(2.2.29)，Microsoft.Bcl (1.1.10) nuget程序包添加到我的程序包后，出现了这些错误 PCL项目，Xamarin表单项目和Xamarin Droid项目.

These errors appeared after adding the Microsoft.Build.Async (1.0.168), Microsoft.Bcl.Build(1.0.21), Microsoft.Net.Http(2.2.29), Microsoft.Bcl (1.1.10) nuget packages to my PCL project, Xamarin forms project and Xamarin Droid project.

此外，使用了Nuget包Xamarin.Forms.Maps (v2.1.0.6508)和Xamarin.Forms (v2.1.0.6508-pre3).

In addition, the Nuget packages Xamarin.Forms.Maps (v2.1.0.6508) and Xamarin.Forms (v2.1.0.6508-pre3) are used.

推荐答案

向PCL项目中添加nuget包PclStorage v1.0.2可以解决警告和部署错误.

Adding the nuget package PclStorage v1.0.2 to the PCL project resolves both warnings and the deployment error.

我不确定为什么存在这种依赖性.

I'm not sure why this dependency is there.
