Checks if the already parsed input message-parameters must be sent through the NLog MessageTemplate Parser for proper handling of message-template syntax (Ex. @) Using the NLog MessageTemplate Parser will hurt performance: 1 x Microsoft Parser - 2 x NLog Parser - 1 x NLog Formatter Allocates object[]-array for after checking for mismatch between Microsoft Extension Logging and NLog Message Template Parser Cannot trust the parameters received from Microsoft Extension Logging, as extra parameters can be injected Are all parameters positional and correctly mapped? true if correct Add Property and init list if needed list with at least one item Find max index of the parameters index, 0 or higher Is logging enabled for this logger at this ?
