I am using version 7.0.6 of Audit.NET. I added the following line to my WEB API registration method
config.Filters.Add(new Audit.WebApi.AuditApiAttribute());
When i run the application it gives the following runtime error
self referencing loop detected with type Appinstance.Path 'Action.ActionParameters.request.Properties.MS_HttpContext.ApplicationInstance.Context'.
I am using latest version of Newtonsoft.JSON from Nuget.
Can you provide the stack trace?
That error means Newtonsoft.Json was unable to serialize an object that has a reference loop, but the json conversion used by default on Audit.NET already handles this, by ignoring the reference loops with ReferenceLoopHandling setting set to Ignore.

Are you using a custom data provider to save the events?
If so, please be sure to use the provided AuditEvent ToJson method, or any other method that handles self references.
