Implement an expression evaluator

Important

In Visual Studio 2015, this way of implementing expression evaluators is deprecated. For information about implementing CLR expression evaluators, see CLR expression evaluators and Managed expression evaluator sample.

Evaluating an expression is a complex interplay among the debug engine (DE), the symbol provider (SP), the binder object, and the expression evaluator (EE). These four components are connected by interfaces that are implemented by one component and consumed by another.

The EE takes an expression from the DE in the form of a string and parses or evaluates it. The EE runs the following interfaces, which are consumed by the DE:

In this section

Expression evaluator implementation strategy defines a three-step process for the expression evaluator (EE) implementation strategy.
