Online Chat: Upgrading COM Applications to .NET with Visual C++ 2005

Many applications consume and expose COM interfaces as their object models
today. And .NET has tools such as tlbimp, tlbexp and COM Interop support for
RCWs and CCWs to help integrate managed code with COM objects. In addition,
there are also a number of options in C++ unavailable to other languages
such as C# or VB. Some mechanisms are simpler to code, while others provide
deeper control over aspects such as data and interface marshaling, custom
interface support and performance tuning. What are these options and when do
I use them? What conveniences does Visual C++ provide to "go deep" but
retain the simplicity of a tool like tlbimp? What goes on under the hood
that I need to be aware of when I provide my own interface wrapping, and why
might I do this? How is the COM apartment model honored when I recompile as
managed code? What AppDomain and threading issues should I be aware of and
how do I avoid any pitfalls? What is the fine-print surrounding areas like
using interface sinks, object lifetime control, and COM capabilities in
mixed or pure images? If you expose or consume COM interfaces in your C/C++
applications today and need to know your options moving forward in .NET then
this chat is for you.
