WCF - compiler can't find TChannel

[Jeff Jarrell]

I want to provide a helper to apply a certificate to svcutil generated
class(s) that derives from ClientBase<TChannel>. But the compiler can't
find "TChannel". I have System.ServiceModel referenced, it finds ClientBase.

The stub looks like this... Any ideas appreciated. Thanks.

using System;
using System.Collections.Generic;
using System.Text;
using System.ServiceModel;

namespace whi.pw.core.webutil
{
public class CertificateResolver
{
public static void Apply(ClientBase<TChannelproxy)
{
}
}
}

Jeff,

This is an issue with not defining the type parameter TChannel. To fix
this, you would do:

public static void Apply<TChannel>(ClientBase<TChannelproxy) where
TChannel : class

The constraint on TChannel comes from the constraint on the type
parameter TChannel in the ClientBase class.

Ok, that did the trick but I don't quite know what it means. Might you
point me to a reference on what the "where TChannel : class". Not so much as
TChannel, just what the "where" means on the method declaration.

thanks,
jeff

Nicholas,
Ok, No need to follow up. I found the reference. The where relates to a
contraint on the Generic interface.

Thanks.
