After adding flags to enum: Wcf error: Error 5 Custom tool error: Failed to generate code for the service reference 'MyService'

Question

on my WCF Service I just change an enum from:

    /// <summary>
/// The DocumentState enum.
/// </summary>
[DataContract]
public enum DocumentState
{
    /// <summary>
    /// Undefined.
    /// </summary>
    [EnumMember]
    Undefined,

    /// <summary>
    /// OK.
    /// </summary>
    [EnumMember]
    Ok
}

to:

    /// <summary>
/// The DocumentState enum.
/// </summary>
[DataContract]
[Flags]
public enum DocumentState
{
    /// <summary>
    /// Undefined.
    /// </summary>
    [EnumMember]
    Undefined = 0,

    /// <summary>
    /// OK.
    /// </summary>
    [EnumMember]
    Ok = 1
}

On the client side I update the WCF References without any Problems but after rebuild I get:

Error 5 Custom tool error: Failed to generate code for the service reference 'MyService'. Please check other error and warning messages for details

Whats wrong with this flag enum?

UPDATE:

Ok.. in the warrnings I found this but this doesn't really helps me:

Warning 1 Custom tool warning: Cannot import wsdl:portType Detail: An exception was thrown while running a WSDL import extension: System.ServiceModel.Description.DataContractSerializerMessageContractImporter Error: Referenced type 'TestSolution.Test.Entities.Documents.Document, TestSolution.Test.Entities, Version=1.1.78.7965, Culture=neutral, PublicKeyToken=7ad0fddf5c57b9b3' with data contract name 'Document' in namespace 'http://schemas.datacontract.org/2004/07/TestSolution.Test.Entities.Documents' cannot be used since it does not match imported DataContract.

UPDATE:Some additional informations for you: - I am using net.tcp binding - The enum is using in min. 50 places (with out the flags attribute) already on the wcf service and on the client - When I create a new enum with the same name but with a 2 at the end of the name all works great! What means really the warnings about the "wsdl:portType" / "wsdl:binding" / "wsdl:port" ???? — p__b_o

When you added the Flag attribute, you changed the way the Enum is stored and made variables of that type capable of holding multiple values. This MSDN post explains the details on how WCF handles this. Unless you actually intend to make that Enum function as a flag field, I'd get rid of it since it needless complicates Enum meaning.
