I'm using MS ILogger and Serilog 2.4.0 as logger implementation (via Serilog.Extensions.Logging 1.4.0).

When I log string
Got ItemsToPrepare 10:[{9,,General,New,{5,,Our Company},,{,,}},{11,,System Administration,New,{5,,Our Company},,{,,}},{6,,Web site creation,New,{4,,Boston Chocolate},,{,,}},{12,,Finance&Accounting,New,{5,,Our Company},,{,,}},{1,,Web site creation,New,{1,,Media Agency},,{,,}}] for input List`1(10:[{9,General,{5,,Our Company}},{11,System Administration,{5,,Our Company}},{6,Web site creation,{4,,Boston Chocolate}},{12,Finance&Accounting,{5,,Our Company}},{1,Web site creation,{1,,Media Agency}}]) and Id(1) I got IndexOutOfRangeException

   в Serilog.Parsing.MessageTemplateParser.ParsePropertyToken(Int32 startAt, String messageTemplate, Int32& next)
   в Serilog.Parsing.MessageTemplateParser.<Tokenize>d__1.MoveNext()
   в System.Linq.Buffer`1..ctor(IEnumerable`1 source)
   в System.Linq.Enumerable.ToArray[TSource](IEnumerable`1 source)
   в Serilog.Events.MessageTemplate..ctor(String text, IEnumerable`1 tokens)

   в Microsoft.Extensions.Logging.Logger.Log[TState](LogLevel logLevel, EventId eventId, TState state, Exception exception, Func`3 formatter)

However, logging Got ItemsToPrepare 10:[{1,Robert,,Barber,{4,Administration,False},{-1,New York Office,True},,New,,,},{4,Maurice,,Gibson,{2,Design,False},{2,London Office,True},,New,,,},{5,Jennifer,,Wooster,{4,Administration,False},{-1,New York Office,True},,New,,,},{9,Barbara,,Kloss,{4,Administration,False},{3,Sydney Office,True},,New,,,},{2,Roy,,O'Dowd,{3,Development,False},{-1,New York Office,True},,New,,,}] for input List`1(10:[{1,Robert,,Barber,{4,Administration,False},{-1,New York Office,True}},{4,Maurice,,Gibson,{2,Design,False},{2,London Office,True}},{5,Jennifer,,Wooster,{4,Administration,False},{-1,New York Office,True}},{9,Barbara,,Kloss,{4,Administration,False},{3,Sydney Office,True}},{2,Roy,,O'Dowd,{3,Development,False},{-1,New York Office,True}}]) and Id(1) is OK.
