Re: Feature request for C# Generic inheritence

This is correct. I thought that for generic inheritance, the compiler will create an explicit type at compile time. Same way anonymous method works.

The trouble is that .NET generics, unlike C++ templates, are completely compiled in generic form. However, all base classes must be known at compile time. Only C++ templates, which are made concrete before being compiled, can inherit from template parameters. However .NET classes can use the curiously recurring template pattern which has some overlapping applications.

Hello,

What do you think about the following features:

public class GenericDecorator<T> : T
{

}

can leverage to a few things:

public interface IChannel
{
void Connect();
void Disconnect();
}

public class TcpChannel : IChannel
{
...
}

public class ChannelDescriber<T> : T where T : IChannel, class
{
public string ChannelName {get; set;}
}

another more complicated example:

public class Extender<T,K> : T
{
public K Data {get;set;}
}

which can be use to :
Extender<EventArgs,string> extender;

extender.Data (give the same ability as EventArgs<T> but more generic which can leverage other types that do not support generics.

Last is for delegates aka

delegate void extendDelegate<T,K>(K t) : T where T : delegate
// K should be added as first parameter.
and usage:

extendDelegate<ThreadStart,string> Start;

Start("hello world");

which means that even further we can do this:

System.Threading.Thread.Start(Start("ido",null)); // anonymous delegates feature

void Start(string name, object state);

you can vote for the feature in the following like:
