随机System.TypeLoadException
Random System.TypeLoadException
我正在使用最新的 Visual Studio 2019 更新构建一个 Xamarin Android 应用程序。
在某些设备上我得到一些我不理解的异常，因为在大多数设备上它似乎都很好。
异常 1：
System.TypeLoadException: Could not resolve type with token 010000a0 from typeref (expected class 'System.St' in assembly 'mscorlib, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e')

异常 2：
System.TypeLoadException: Could not set up parent class, due to: Could not load type of field 'System.Net.Http.HttpClientHandler:<DangerousAcceptAnyServerCertificateValidator>k__BackingField' (2) due to: Could not resolve type with token 0100003b from typeref (expected class 'System.Security.Cryptography.X509Certificates.X509Chais' in assembly 'System, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e') assembly:System, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e type:System.Security.Cryptography.X509Certificates.X509Chais member:(null) assembly:System.Net.Http.dll type:HttpClientHandler member:(null)
异常 3：

异常 4：
System.TypeLoadException: Could not resolve type with token 01000071 from typeref (expected class 'System.Net.Http.HttpRequestException' in assembly 'System.Net.Http, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a') assembly:System.Net.Http, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a type:System.Net.Http.HttpRequestException member:(null)
似乎无法在某些设备上找到来自“System.Net.Http”的某些程序集或 类。我尝试将“AndroidLinkMode”从“SdkOnly”更改为“None”并检索了一个更大的 APK 文件，但问题仍然存在。
编辑：
我正在使用 Azure Dev Ops 部署的 NuGet 包（与我的计算机不同的代理）。 Visual Studio 是最新的并且所有包引用都具有相同的版本。
我可以通过在项目属性的“Android 选项”下启用“将程序集捆绑到本机代码”来解决这个问题，希望如此。
