Microsoft .NET Framework 3.5

The Microsoft .NET Framework version 3.5 redistributable package installs the .NET Framework runtime and associated files required to run applications developed to target the .NET Framework v2.0.
The .NET Framework version 3.5 improves scalability and performance of applications with improved caching, application deployment and updating with ClickOnce, support for the broadest array of browsers and devices with ASP.NET 3.5 controls and services.
The .NET Framework is Microsofts managed code programming model for building applications that have visually stunning user experiences, seamless and secure communication, and the ability to model a range of business processes. In addition to the .NET Framework 3.5, it includes Windows Presentation Foundation (WPF), Windows Workflow Foundation (WF), Windows Communication Foundation (WCF), and Windows CardSpace.
All known breaking changes in the .NET Framework 3.5 have been reviewed in detail. Breaking changes were made for a number of reasons, including standards compliance, customer feedback, and correctness. We have attempted to be exhaustive in documenting changes in the attached file, but believe that many of these changes will impact very few users. An example of several of the types of run-time changes follows:
- Standards Compliance: The ISO tag in System.Globalization for Kyrgyzstan was updated from KZ to KG.
- Customer Feedback: The ASP.NET project model was changed in response to customer feedback.
- Correctness: Floating point precision was increased in certain cases. This is something which was already documented in the CLI specification as being possible.
