在PDC上，Misha Shneerson和Andrew Whitechapel的Session：Under the Hood: Advances in the .NET Type System中披露了.NET 4.0中Interop的新功能：Type Equivalency，而內部我們都將這個Feature稱之爲NO PIA(Primary Interop Assembly)。這個Feature是VB/C#/Interop小組共同努力合作完成的，可以說是CLR Interop在.NET 4.0中最大的改進之一。我會在接下來的幾篇Blog中介紹我們爲什麼要做這個Feature，以及這個Feature的使用方法，工作原理，等等。如果有時間，我也會考慮做一個Webcast。想先睹爲快的朋友可以先下載Video和PPT：
TL02 Under the Hood: Advances in the .NET Type System
Misha Shneerson, Andrew Whitechapel
Enhancements to the type system in the next version of .NET Framework allow for loose type-coupling of components comprising your application. This talk is an in-depth examination of the changes in the Common Language Runtime and managed languages. See how these changes help to simplify versioning and deployment of components targeting either COM based and/or fully managed applications. For Office developers, learn how to eliminate the need to redistribute primary interop assemblies.
