Microsoft support for .NET

Microsoft supports .NET on multiple operating systems, per the Microsoft Modern Lifecycle.

Support is provided for: .NET SDK, .NET runtime, ASP.NET Core, and EF Core.

Support has two key benefits:

• Patches are provided (for free) as required for functional or security issues, typically monthly.
• You can contact Microsoft support to request help (potentially at a cost).

You can also request community support on GitHub (for free), but there is no guarantee on a quick reply.

Support is conditional on using the latest .NET patch update and a supported operating system, as defined by:

• Microsoft support policy
• .NET releases
• .NET release policies
• .NET supported operating system lifecycle.

Knowing key dates for a product lifecycle helps you make informed decisions about when to upgrade or make other changes to your software and computing environment.
