The .NET Programming Model makes a clean distinction between Reference and Value on three different levels. These three levels interact directly, and it is important to understand the distinction. This article may be old hat to many of you, but it is...

As I noted we also unveiled yesterday the Managed Addin Framework (MAF). MAF is necessary realization of the Addin Model architecture. It is included in two assemblies: System.Addin and System.Addin.Contract. These assemblies will ship first with the...

OK, I know I said my next post would be an in depth treatment of IContract, but I remembered I wanted to fininsh something I started with my earlied post Addins in .NET . I noted there that .NET currently was still analogous to the LoadLibrary\GetProcAddress...

In my post What is an Addin? I said that a "contract" is just that: "a previously decided upon method of communication with rules and limitations." Here is where we discuss the rules and limitations for .NET Addin contracts. In my post Addins in .NET...

I know its been a while, but I've been busy coding lately. That code will become public fairly soon, so I'll talk about it then. I'm still working on the promised Proxies and Adapters post, it will be coming, I promise. But in the meantime, the subject...

Those of you who have been following my blog will note that I have retroactively added some categories. I hadn't bothered with categories in the past because almost all of my posts have been about MAF. Well, now that MAF is a real thing, we (meaning...
