在我的 AppHost 上调用 Init() 时出现上述错误。
这是一个干净的 asp.net v 4.5 空 Web 应用程序,按照入门教程提供了一个简单的 HelloWorld 服务。
我专门使用安装了旧版本的 ServiceStack:
Install-Package ServiceStack -Version 3.9.71
其中安装参考:
ServiceStack.dll 3.9.70.0
ServiceStack.Common.dll 3.9.9.0
ServiceStack.Interfaces.dll 3.9.9.0
ServiceStack.OrmLite.dll 3.9.14.0
ServiceStack.OrmLite.SqlServer.dll 1.0.0.0
ServiceStack.Redis.dll 3.9.11.0
ServiceStack.ServiceInterface.dll 3.9.70.0
ServiceStack.Text.dll 4.0.11.0
我得到的错误是:
[TypeLoadException: Could not load type 'ServiceStack.ServiceHost.IService' from assembly 'ServiceStack.Interfaces, Version=3.9.9.0, Culture=neutral, PublicKeyToken=null'.]

它说它无法加载类型,但我不知道为什么?
以下是 nuget 的输出:
