我是.NET Core的新手，正在尝试使用WCF服务。当我使用生成的代理类和配置并尝试使用dotnet运行时，使用Microsoft SDKs / Windows / v7.0A / Bin中的svcutil生成了代理类。出现错误
error CS0246: The type or namespace name 'Order' could not be found (are you missing a using directive or an assembly reference?)
error CS0234: The type or namespace name 'MessageContractAttributeAttribute' does not exist in the namespace 'System.ServiceModel' (are you missing an assembly reference?)
error CS0246: The type or namespace name 'IsWrapped' could not be found (are you missing a using directive or an assembly reference?)
error CS0234: The type or namespace name 'OperationContractAttributeAttribute' does not exist in the namespace 'System.ServiceModel' (are you missing an assembly reference?)
试图在vscode中添加System.ServiceModel.Primitives，但没有运气出错
error NU1100: Unable to resolve 'System.ServiceModel.Primitives (>= 4.5.3)' for '.NETCoreApp,Version=v2.1'
尝试以下步骤
