Today we got one step closer to building manageable applications. On codeplex, right now, is the bright shiney new Visual Studio Management Model Designer.
The designer, available on Codeplex at http://www.codeplex.com/dfo , is built upon the Visual Studio DSL. The designer allows Architects to describe a health model including defining Managed Entities, Aspects and Health State Indicators, as well as specifying abstract and concrete implementations for multiple trust levels.
Furthermore the health model can be used to auto-generate the actual .net implementation code for writing events and performance counters. This will significantly reduce the amount of developer effort required to build manageable applications.
There is also a 300+ page guide on how to use the tool and design for operations in general which will be available next week.
Although the tool is a prototype/CTP, it is fully functional and can be used today to make your applications more manageable.
