c# - Why in asp.net mvc enabling provider at ETW session throws error?

Question

This is the code part, where throws error

_traceEventSession = new TraceEventSession(SessionName, TraceEventSessionOptions.Create);
_traceEventSession.EnableProvider(
                ClrTraceEventParser.ProviderGuid,
                Microsoft.Diagnostics.Tracing.TraceEventLevel.Verbose,
                (ulong)(ClrTraceEventParser.Keywords.Threading | ClrTraceEventParser.Keywords.Contention));

Error throws at calling EnableProvider

In local environment all ok and I don't use KernelProvider, so I really can't understand why it's happen. Also I added all permissions for IIS_IUSRS in .NET Common Language Runtime provider section, but it didn't help at all.
