Live Event: The C# Programming Language (2): Variance

This Friday noon I am going to perform a presentation on the Live Meeting. The topic is the variance in C#. Variance (including covariance and contravariance) is a break change to the CLR version 4.0 as well as the C# 4.0. The topic will cover:

• Generics
• Closed and Open types
• Covariance
• Contravariance
• Variance in reference types
• Array covariance and contravariance
• Interface covariance and contravariance
• Delegate covariance and contravariance
• CLR 4.0 built-in co- and contravariance enabled types
• IEnumerable<out T>
• Action<in T>
• Func<in T, out TResult>
• · Variance rules

Anyone who interested in this topic, please join the Live Meeting event. See below for details.
