    have a WCF service issue. I made some changes to the service rename/added/removed services. Solution builds fine but when I reference this WCF service from a test solution...getting this error. It seems like there are some old references that haven't been removed. Looking for some feedback on how to resolve this. Thanks Jay

    Hi,

    >>Error: Cannot obtain Metadata from http://localhost:1141/Well/WellService.svc
    If this is a Windows (R) Communication Foundation service to which you have acce
    ss, please check that you have enabled metadata publishing at the specified addr
    ess.  For help enabling metadata publishing, please refer to the MSDN documentat
    ion at http://go.microsoft.com/fwlink/?LinkId=65455.

    When occur the above error, please make sure you have enabled the metadata as following:

    <services>  
<service behaviorConfiguration="metadataBehavior" name="MyService">    
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />  
</service>
</services>
<behaviors>  
<serviceBehaviors>    
<behavior name="metadataBehavior">      
<serviceMetadata httpGetEnabled="true" />    
</behavior>  
</serviceBehaviors>
</behaviors>

    In addition, please make sure your service references that behavior.

    <service name="MyService" behaviorConfiguration="metadataBehavior">

    >>The service cannot be activated because it does not support ASP.NET compatibility. ASP.NET compatibility is enabled for this application. Turn off ASP.NET compatibility mode in the web.config or add the AspNetCompatibilityRequirements attribute to the service type with RequirementsMode setting as 'Allowed' or 'Required'.

    When occur the above error, please mark your service as following:

    [AspNetCompatibilityRequirements(
        RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]

    Because when you set aspNetCompatibilityEnabled to true in your config file, you are stating that your services will participate in the ASP.NET pipeline; so items like ASP.NET session are available. You need to decorate your services appropriately if this is the case, since ASP.NET Compatibility Mode is set to false by default.
    So by decorating your service implementation with a RequirementsMode of Allowed, you're stating a happy middle ground that basically says your service doesn't care what the aspNetCompatibility mode is (true or false). If your RequirementsMode is Required, then you need to have the config aspNetCompatibilityEnabled set to true; the opposite is true if your RequirementsMode is set to NotAllowed.
