无法在 Visual Studio 2015 中运行 WCF 服务应用程序 [英] Can't run WCF service application in Visual Studio 2015

问题描述

我正在尝试创建我的第一个 WCF 服务应用程序，但我无法让它从 Visual Studio 2015 运行.

I'm trying to create my first WCF service application, but I can't get it to run from Visual Studio 2015.

这是我点击运行时得到的错误...

This is the error I get when I click run...

我正在学习教程，我认为他们跳过了几个步骤，但这是我添加到 web.config 的内容

I was following a tutorial and I think they skipped a few steps, but here's what I added to the web.config

<services>
  <service name="OnPatrolRest.Service1">
    <endpoint address="http://localhost:51964/service1"
          binding="webHttpBinding"
          contract="OnPatrolRest.IService1"/>
  </service>
</services>

这是界面

    <ServiceContract()>
Public Interface IService1

    <OperationContract()>
    Function GetData(ByVal value As Integer) As String

    <OperationContract()>
    Function GetDataUsingDataContract(ByVal composite As CompositeType) As CompositeType

    <OperationContract()>
    <WebInvoke(Method:="GET", ResponseFormat:=WebMessageFormat.Json, UriTemplate:="/getPerson?id={id}")>
    Function getPerson(ByVal id As String) As Person

End Interface

对于类文件...

Public Function getPerson(ByVal id As String) As Person Implements IService1.getPerson
        Dim p As New Person

        p.Id = Convert.ToInt32(id)
        p.Name = "Sterling Archer"

        Return p
    End Function

这是我添加的唯一功能.我错过了什么.我对此很陌生.我看到的每个帖子都是几年前的，在 VS 2015 中不起作用.

That's the only function I added. What am I missing. I'm very new to this. Every post I've seen is from years ago and doesn't work in VS 2015.

非常感谢您的帮助！！！

Thank you very much for any help!!!

推荐答案

这对我有用，在控制台应用程序中.不需要 Web.config 或 App.config.

This works for me, in a Console app. No Web.config or App.config necessary.

主模块

Module Main
  Sub Main()
    With New Manager(GetType(Service), "SomeService", 8080)
      Environment.ExitCode = .StartService
    End With
  End Sub
End Module

服务经理

Friend Class Manager
  Implements ServiceControl

  Public Sub New(ServiceType As Type, ServiceName as String, WcfPort As Integer)
    Me.ServiceType = ServiceType
    Me.ServiceName = ServiceName
    Me.WcfPort = WcfPort
  End Sub



  Public Sub StartService
    Try
      Me.OpenServiceHost()

    Catch ex As Exception

    End Try
  End Sub



  Public Sub StopService
    Try
      Me.CloseServiceHost()

    Catch ex As Exception

    End Try
  End Sub



  Public Sub OpenServiceHost()
    Me.ServiceHost.Open()
  End Sub



  Public Sub CloseServiceHost()
    If Me.ServiceHost.IsNotNothing Then
      If Me.ServiceHost.State <> CommunicationState.Closed Then
        Me.ServiceHost.Close()
      End If
    End If
  End Sub



  Private ReadOnly Property ServiceHost As ServiceHost
    Get
      If _ServiceHost Is Nothing Then
        _ServiceHost = New ServiceHost(Me.ServiceType, Me.ListenerAddress)
        _ServiceHost.AddDefaultEndpoints()
      End If

      Return _ServiceHost
    End Get
  End Property
  Private _ServiceHost As ServiceHost



  Private ReadOnly Property ListenerAddress As Uri
    Get
      Return New Uri($"http://{Environment.MachineName}:{Me.WcfPort}/{Me.ServiceName}")
    End Get
  End Property



  Private Property ServiceName As String
  Private Property WcfPort As Integer
End Class

服务接口

<ServiceContract>
Public Interface IService
  <OperationContract> Function GetFilteredResult(Workstations As List(Of String), ProcessName As String) As Result
  <OperationContract> Function GetResult(Workstations As List(Of String)) As Result
End Interface

服务实施

Public Class Service
  Implements IService

  Public Function GetFilteredResult(Workstations As List(Of String), ProcessName As String) As Result Implements IService.GetFilteredResult
    '
    ' Code goes here
    '
  End Function



  Public Function GetResult(Workstations As List(Of String)) As Result Implements IService.GetResult
    '
    ' Code goes here
    '
  End Function
End Class

我通常将它们与 TopShelf 配对；这种组合提供了一个很好的自托管 WCF 服务，它封装在一个 Windows 服务中.

I usually pair these with TopShelf; the combination provides a nice self-hosted WCF Service wrapped in a Windows Service.
