azure - 添加对 Azure Blob 存储的 nlog 支持后，Xamarin 版本构建失败

Question

将 NLog 添加到我们的 Xamarin 表单应用并支持 Azure Blob 存储后，Android 版本构建失败，并显示以下内容:

Error       Mono.Linker.MarkException: Error processing method: 'System.Void Microsoft.Azure.Services.AppAuthentication.AdalAuthenticationContext/<AcquireTokenAsync>d__3::MoveNext()' in assembly: 'Microsoft.Azure.Services.AppAuthentication.dll' ---> Mono.Cecil.ResolutionException: Failed to resolve System.Threading.Tasks.Task`1<Microsoft.IdentityModel.Clients.ActiveDirectory.AuthenticationResult> Microsoft.IdentityModel.Clients.ActiveDirectory.AuthenticationContextIntegratedAuthExtensions::AcquireTokenAsync(Microsoft.IdentityModel.Clients.ActiveDirectory.AuthenticationContext,System.String,System.String,Microsoft.IdentityModel.Clients.ActiveDirectory.UserCredential)

我已将其追溯到包NLog.Extensions.AzureBlobStorage，并看到该包具有Microsoft.Azure.Services.AppAuthentication作为依赖项(这是在错误消息中!)。

我发现:https://stackoverflow.com/a/69050534/11269239这是有点相似，但不同的二进制文件。已尝试设置链接器文件，但似乎无法解决...

阅读本文:https://learn.microsoft.com/en-us/xamarin/cross-platform/deploy-test/linker 我尝试了很多组合，但认为这是最精确的。

<linker>
    <assembly fullname="Microsoft.IdentityModel.Clients.ActiveDirectory">
        <type fullname="AuthenticationContextIntegratedAuthExtensions">
            <method name="AcquireTokenAsync" />
        </type>
    </assembly>
</linker>

并将构建操作设置为 LinkDescription。

我也尝试过通配符......不知道我做错了什么:(

新更新的 NLog.Extensions.AzureBlobStorage 版本 4.0 现已发布，它从旧版 AzureServiceTokenProvider 切换到新的 Azure.Identity:

https://www.nuget.org/packages/NLog.Extensions.AzureBlobStorage

希望它能解决 Android 平台上的构建问题
