MethodAccessException：方法 X 尝试访问方法 Y 在 Dynamics 365 Plugin On Prem 中失败

Question

在 Dynamics 365 v9.1 中尝试将插件从 .NET 版本 4.5.2 移动到 4.6.2 时出现以下错误

 System.AggregateException: One or more errors occurred. ---> System.MethodAccessException: Attempt by method 'System.Net.Http.WinHttpResponseParser.GetReasonPhrase(System.Net.HttpStatusCode, Char[], Int32)' to access method 'System.Net.HttpStatusDescription.Get(System.Net.HttpStatusCode)' failed.

我可以部署插件并且它工作正常。当插件尝试对我们从插件

调用的外部 API 进行 Web 服务调用时，出现上述错误

该插件未处于沙盒模式并且已在数据库中注册

我用 JustDecompile 打开了插件程序集，并追踪到 System.dll 中加载一个方法的问题，看起来它试图从 GAC 加载它但失败了。

有人遇到同样的问题吗？这个相同的插件在 .NET 4.5.2 中工作，但在 4.6.2

中失败

我们设法为此找到了解决方案，问题是 ILMerge 包含所有 System.*.dll，阅读此 Whosebug 答案

You might want to avoid merging anything that's part of the .NET Framework (which I assume that libraries like System.Memory and System.Threading.Tasks are).

因此在 .NET 项目文件中为 ILMerge 添加行 <Files Remove="$(TargetDir)System*.dll" /> 解决了这个问题，这确保了运行 ILMerge

时不包含文件

<Target Name="ILMerge" AfterTargets="Build">
<ItemGroup>
    <Files Include="$(TargetDir)*.dll" />
    <Files Remove="$(TargetDir)$(AssemblyName).dll" /> 
    <Files Remove="$(TargetDir)AntiXSSLibrary.dll" />
    <Files Remove="$(TargetDir)Microsoft*.dll" />
    <Files Remove="$(TargetDir)System*.dll" />
</ItemGroup>
