问题描述
我几乎已经将vb中的ASMX中的服务迁移到了基于WCF 4.0的新版本，但是由于在启动时收到消息，所以我无法运行它:
I've almost migrated service in ASMX in vb to new WCF 4.0 based, but I can't run it because I get an message at start:
WCF Service Host cannot find any service metadata. This may cause the client application to run improperly. Please check if metadate is enabled. Do you want to exit?
我不知道此app.config有什么问题.
I don't know what's wrong with this app.config.
您能看看并帮助我吗?

推荐答案
您的WCF服务是一个库(DLL)吗?我问是因为您发布的配置文件中包含以下行:
Is your WCF service a library (DLL)? I ask because of the following line in the config file you posted:
< !!-部署服务库项目时，必须将配置文件的内容添加到主机的app.config文件.System.Configuration不支持库的配置文件.->
如果您的服务是DLL，则需要在主机的配置文件中发布< system.serviceModel> 部分.对于IIS，该文件为web.config文件；对于Windows服务或自托管服务，它将是app.config文件.如上面的注释行所述，服务库不使用它们自己的配置文件，而是使用主机的配置文件.
If your service is a DLL, then you'll need to post the <system.serviceModel> section in the host's config file. For IIS, that would be the web.config file; for a Windows Service or self-hosted service, it would be the app.config file. As the commented line above says, service libraries do not use their own config files, they utilize the host's config file.
