Hosting .NET Controls in IE from the local file system

Today I had a discussion about hosting .NET components in IE from the local file system.

Referencing .NET assemblies that are downloaded from the web server can be done easily using the <OBJECT> tag.

However, using assemblies from the file system, the .NET component has to be registered with COM information, and installed in the global assembly cache.

How to is demonstrated in the knowledge base article 305624.


First Iceland .NET User Group

The .NET User Group Iceland was approved with INETA.

Thanks to Gisli Olafsson who is the user group leader, the group already had a very successful first meeting with 86 attendees. The meeting was about public available information from Whidbey, Yukon, Longhorn, Indigo (see this post).

Anders Hejlsberg - Delegates, Components, and Simplexity

A conversation with Anders Hejlsberg - by Bill Venners with Bruce Eckel.

Anders compares delegates with Java's version of interfaces.

In part 2 of this series, The Trouble with Checked Exceptions, Anders explains why there are no checked exceptions in C#.

Part 1 is about The C# Design Process.

Eric, thanks for the link!

Generic Terms and Custom Collections

Eric Gunnerson posts about generic terms:

open type, type parameter, constructed type, type argument, generic method, arity

Arity was new to me.

In a second post Generics and Object Collections he mentions a design guideline to expose custom collection classes instead of generic collections. Fully agree :-)
I'm doing this already with .NET 1, just the implementation of the custom collection classes will change with v2.

class EmployeeIDCollection: List<int>
