Microsoft has issued the second Microsoft .NET Framework service pack, which the company recommends all users download and install. The .NET Framework Service Pack 2 (SP2) release focuses on security issues and other problems Microsoft has found since SP1's release; this release also includes all the fixes from .NET Framework SP1.

The company says this release is targeted to several customer groups, including developers who are creating Microsoft .NET-based applications and services, Visual Studio .NET users, administrators who want to deploy the update throughout an organization or development team, and end users who want to take advantage of .NET applications and services.

Because SP2 is considered a critical update, Microsoft will soon release it to Windows Update. Developers and other interested parties can download the release now, however, from the Microsoft Web site. Note that you can't uninstall SP2.
