Assembly: System (in system.dll)
Traces generated from a single logical operation can be tagged with an operation-unique identity, in order to distinguish them from traces from a different logical operation. For example, it may be useful to group correlated traces by ASP.NET request. The CorrelationManager class provides methods used to store a logical operation identity in a thread-bound context and automatically tag each trace event generated by the thread with the stored identity.
Logical operations can also be nested. The LogicalOperationStack property exposes the stack of nested logical operation identities. Each call to the StartLogicalOperation method pushes a new logical operation identity onto the stack. Each call to the StopLogicalOperation method pops a logical operation identity off the stack.
Logical operation identities are objects, allowing the use of a type for a logical operation identity.
