SAPCore3.1-无法加载'System.ServiceModel.Activation.VirtualPathExtension‘类型

Question

我有一个托管REST服务的.NET Core 3.1应用程序，我正在为一些端点合并some实用程序。我在Windows 10上。

在通过执行RfcConfigParameters建立新RfcConfigParameters parameters = new RfcConfigParameters()时，我通过其中一个端点遇到了一个错误

错误跟踪如下：

2022-01-14 12:49:41.982 -05:00 [ERR] LookupRfcAttributes Error: System.TypeLoadException: Could not load type 'System.ServiceModel.Activation.VirtualPathExtension' from assembly 'System.ServiceModel, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

我跟随了这么多关于解决类似问题的文章和指南，但一直未能解决。我已经启用/禁用了所有Windows功能。我已经从IIS中删除了ServiceModel。我甚至完全禁用了.NET 3.5，感觉好像有冲突。我尝试过通过.NET v4注册aspnet_regiis.exe -iru，但它告诉我通过"Windows“或”done“来管理它，我已经这样做了。

下面是一些可以帮助我回答问题的截图：

请帮帮我！谢谢。

Answer 1

我想，这不是您想要听到的，但是请检查NCo 3.0的发布和支持策略。上面写着：

支持的.NET Frameworks2.0、3.0、3.5、4.0、4.5、4.6、4.7和4.8。

这意味着.NET Core完全不受NCo支持。.NET核心与经典的.NET框架不一样。如果您的应用程序必须是.NET核心应用程序，那么我怀疑您是否能够使用当前的NCo。

不幸的是，SAP还没有为NCo核心环境发布任何.NET版本。
