Trace.Write(TContext) Method (Func(TContext, String), TContext, MessageType, Nullable(Guid))

Trace Write TContext Method (Func TContext, String , TContext, MessageType, Nullable Guid )

NFX Class Library

[This is preliminary documentation and is subject to change.]

A simplified method for tracing that doesn't evaluate text generation function if tracing is disabled by configuration. It takes context argument that can be passed to the text-generating textFunc functor
