- sectionName
- The name of the code section to appear in the trace. This may be at most 127 Unicode code units long.
Writes a trace message to indicate that a given section of code has begun. This call must be followed by a corresponding call to Trace.EndSection on the same thread.
At this time the vertical bar character '|', newline character '\n', and null character '\0' are used internally by the tracing mechanism. If sectionName contains these characters they will be replaced with a space character in the trace.
