A Modular View of the FutureIIS 7’s 40 Setup Components

IIS7: Modularization

Thomas Deml

Lead Program Manager



• Slim & Efficient

• Install only the components you need

• Reduce attack surface to minimum

• Five times more granular than existing IIS versions

• Servicing and patching on a per component basis

• If you don’t install it, you won’t need to patch it

Security & IIS 7.0Security & IIS 7.0

Extensibility in IIS 7.0

• A review: Extensibility in IIS 6

• Re-built Core Server with new Win32 API

• Full IIS Pipeline support for ASP.NET 2.0

• Internet Server API (ISAPI)

• ISAPI Filters

• ISAPI Extensions

• Pitfalls:

• Big Learning Curve for new & experienced Developers

• Lacks support for Managed Code Developers

• Locked, static set of API’s not easily expanded from release to release

Extending IIS7

Thomas Deml




• Core Server• Brand new Win32 Native Interface

• ALL IIS modules written using this interface

• Unlike ISAPI, IIS team uses this very API just like you will

• Full ASP.NET 2.0 Support

• iHttpModule Interface available TODAY supported

• ASP.NET 2.0 Handlers run exactly as they do today

• Configuration• Fully extensible using XML schema files

• IIS Manager (User Interface)• Using .NET 2.0, extend IIS Manager capabilities

• Diagnostics• Add your events directly into our pipeline

Extensibility & IIS 7.0Extensibility & IIS 7.0

Brand New Configuration in IIS 7.0

• Distributed Configuration for IIS & ASP.NET

• Fully non-administrative delegation

• IIS & ASP.NET Configuration: Side-by-Side

• Metabase: Going, going, … GONE!

• Old metabase pushed to new configuration

• Property names stay the same

• Central File: ApplicationHost.config

• Strongly typed Schema

• Uses ASP.NET semantics for .config files

• Full Distributed Configuration

• Use only ApplicationHost.config using IIS 7 defaults

• Unlock: Give application developers control of individual sections, collections, elements, and more!

Configuration & IIS 7.0Configuration & IIS 7.0

• Metabase Inheritence

• Repetitive

• Large collections of Multi-strings (multi-sz) & Flags
