Swashbuckle配置错误

Question

我正在尝试将Swashbuckle添加到我的ASP.NET MVC WebAPI项目中。我在Visual Studio 2013中使用了一个空的MVC项目模板。后来我添加了所需的文件/包等，但不知何故我无法将Swashbuckle集成到其中。每次我运行这段代码时，在SwashConfig.cs中都会出现以下错误。

以下是我的web.config

有些地方非常不对劲。请帮帮忙。

Answer 1

我认为你的错误之处可能是你在SwaggerConfig上注释掉了这行代码：

[assembly: PreApplicationStartMethod(typeof(SwaggerConfig), "Register")]

然后，您决定在RoutesConfig注册了所有路由之后运行此行代码，

GlobalConfiguration.Configure(config => SwaggerConfig.Register(config))；

您应该尝试删除上面的行，并尝试根据默认行为允许SwaggerConfig在PreApplicationStartup上运行。

对我来说，这个错误信息..(我只在Web中使用了swagger )建议您尝试在管道的后期添加swagger to0的路由。

祝好运。
