The System.Runtime.ConstrainedExecution.ReliabilityContractAttribute attribute provides a mechanism for you to document your code, and to indicate what type of reliability guarantees you can make in the face of exceptional conditions that could potentially lead to an inconsistent state. In this context, exceptional conditions are defined as asynchronous exceptions that can be generated at run time by the common language runtime, such as aborted threads, out-of-memory situations, and stack overflows. You can apply the System.Runtime.ConstrainedExecution.ReliabilityContractAttribute attribute to assemblies, types, and methods.

Use this attribute with the System.Runtime.ConstrainedExecution.Consistency enumeration to define a reliability contract by documenting the level of reliability in a particular piece of code.
