Question

我使用自定义用户名和密码验证创建了一个简单的测试wcf服务。当我启动该服务时，我收到此错误：“无法从程序集'BBT.Sunet.ServiceFassade.WebServices'加载类型'BBT.Sunet.ServiceFassade.WebServices.MyBasicAuthentication'。” 这是堆栈跟踪：

这是服务：

Public Class Service1
Implements IService1

''' <summary>
''' Test
''' </summary>
Public Sub New()
End Sub

''' <summary>
''' Test
''' </summary>
Public Function GetData(ByVal aValue As Integer) As String Implements IService1.GetData
    Return String.Format(CultureInfo.CurrentCulture, "You entered: {0}", aValue)
End Function

使用此web.config：

  <system.serviceModel>
<behaviors>
  <serviceBehaviors>
    <behavior name="BasicAuthBehavior">
      <serviceMetadata httpGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="true" />
      <serviceCredentials>
        <userNameAuthentication userNamePasswordValidationMode="Custom" customUserNamePasswordValidatorType="BBT.Sunet.ServiceFassade.WebServices.MyBasicAuthentication, BBT.Sunet.ServiceFassade.WebServices" />
      </serviceCredentials>
    </behavior>
    <behavior name="WinAuthBehavior">
      <serviceMetadata httpGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="false" />
    </behavior>
  </serviceBehaviors>
</behaviors>

<bindings>
  <basicHttpBinding>
    <binding name="BasicAuthBinding">
      <security mode="TransportWithMessageCredential">
        <message clientCredentialType="UserName" />
        <transport clientCredentialType="None" />
      </security>
    </binding>
    <binding name="WinAuthBinding">
      <security mode="TransportCredentialOnly">
        <transport clientCredentialType="Windows" />
      </security>
    </binding>
  </basicHttpBinding>
</bindings>
<services>      
  <service behaviorConfiguration="BasicAuthBehavior" name="BBT.Sunet.ServiceFassade.WebServices.Service1">
    <endpoint address="" binding="basicHttpBinding" bindingConfiguration="BasicAuthBinding"
      contract="BBT.Sunet.ServiceFassade.WebServices.IService1" />
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
  </service>
</services>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />

这是UserNamePasswordValidator：

Public Class MyBasicAuthentication
Inherits UserNamePasswordValidator

Public Overrides Sub Validate(ByVal userName As String, ByVal password As String)
    If Not (userName.Equals("user") AndAlso password.Equals("password")) Then
        Throw New FaultException("Incorrect Login!")
    End If
End Sub

结束班

一切都在同一个集会中。我使用本地IIS进行调试。我有另一个wcf服务，也在这个IIS上使用基本身份验证，所以IIS配置应该没问题。我将所有内容与工作服务进行了比较，但我没有发现错误。有人能帮助我吗？
