The events described in this article collect information that is specific to methods. The payload of these events is required for symbol resolution. In addition, these events provide helpful information such as methods that are loaded and unloaded. For more information about how to use these events for diagnostic purposes, see logging and tracing .NET applications
All method events have a level of "Informational (4)". All method verbose events have a level of "Verbose (5)".
All method events are raised by the JITKeyword (0x10) keyword or the NGenKeyword (0x20) keyword under the runtime provider, or JitRundownKeyword (0x10) or NGENRundownKeyword (0x20) under the rundown provider.
The V2 versions of these events include the ReJITID, the V1 versions do not.
