Advice on mixing legacy ASP site with .NET 2.0

Question

We've just been tasked with updating an e-commerce application to use PayPal's PayFlow product. The site was originally written in classic ASP except for the credit card processing portion which was a COM component.

Our plan is to replace the COM component with a .NET 2.0 component. I'm looking for tips, gotcha, etc. before we embark.

I think Dan Bartels' blog post about Replacing Old Classic ASP COM Componenets With .NET Assemblies is the right starting point for you.

Implementing the details described in the blog post, you should be able to instantiate your objects in classic asp and execute code like this:

Dim myObject
Set myObject = Server.CreateObject("MyWebDLL.MyClass")
Response.Write myObject.MyMethod("test")
