Process Model
 New process model for ASP.NET and Indigo
 Very flexible activation
 ASP.NET Runtime is managed!
•ISAPI-Filter
 Runs as ASPNET user account
 Asynchronous execution of requests
•Own Thread-Pool
•Threads are not related to IIS Threads
 Multithreaded
•No Apartment-Model
 Alternative Filtering-Model
•HTTP-Modules und -Handlers replace ISAPIFilters
 Cache

Coding Model
 Reduce Inheritance Complexity
 No need for declaration code
 Code is linked by Visual Studio and the runtime
 Hot Updates (XCopy deployment)
 Full Integration in the .NET Framework
•Consistent programming model, same tools

12. © 2005 newtelligence Aktiengesellschaft. All rights reserved
Codebehind
 Enable separation of code from content
•Developers and designers can work
independently
