.NET Support

The Telerik Extensions for ASP.NET MVC Support Lifecycle (TESL) policy applies to all current and new Telerik customers worldwide. The goal of this policy is to make Telerik’s support timelines clear and predictable so that customers can make plans for their own support and product planning based on the knowledge of Telerik’s Support Lifecycle.

Telerik MVC Extensions Support

Telerik will offer a minimum of 2 years of Mainstream Support for each version of the MVC Extensions. Once a new version of the ASP.NET MVC framework has been released, Telerik will offer 1 additional year of Mainstream Support for the previous framework version. After that year has elapsed, Telerik will provide 2 additional years of Limited Support for the previous framework version. Extended Support for a previous framework version of Telerik MVC Extensions will begin 3 years after a new version has been released.

Support Types

Mainstream Support is the highest level of support for Telerik MVC Extensions. While covered by Mainstream Support, our MVC Extensions will receive full product support through all support channels, all new components added to the MVC suite, all product feature enhancements, all bug fixes, and free support incidents (with a current commercial license). When a product suite enters Limited Support, it will continue to receive all bug fixes and support through all support channels. It will not, however, receive all new product feature enhancements or new components. Only features and components that do not depend on newer framework features will be added during Limited Support. Finally, when a product enters the Extended Support phase, it will no longer receive active support. Support for these products will be available on a pay by incident basis and will be available for at least 2 years after a product suite leaves the Limited Support phase.

The following chart shows the differences between the three support phases for Telerik MVC Extensions:

	Mainstream Support	Limited Support	Extended Support
New components	All	Limited	None
Components Enhancements	All	Limited	None
Bug Fixes	All	All	None
No-charge incident support	Yes	Yes	No
Paid Support	Included in Commercial License	Included in Commercial License	Per Incident

Current Framework Support

Based on this policy, this is how the current .NET framework versions are supported:

• Telerik Extensions for ASP.NET MVC 1.0 (under.NET 3.5 SP1), introduced Q2 2009
  Current Support Phase: Mainstream (began Q2 2009)
• Telerik Extensions for ASP.NET MVC 2.0 (under .NET 3.5 SP1/.NET 4), introduced Q1 2010
  Current Support Phase: Mainstream (began Q1 2010)
• Telerik Extensions for ASP.NET MVC 3.0 (under .NET 3.5 SP1/.NET 4), introduced Q3 2010 SP1
  Current Support Phase: Mainstream (began Q3 2010 SP1)

This policy is effective immediately and applies to all Telerik Extensions for ASP.NET MVC suites. Telerik reserves the right to amend this policy as required by shifting customer demand and marketplace forces.
