The type must 'xx' derive from ITraceWriter.\r\nParameter name: service

[Resolved]

Problem

I was getting following error while registering a custom tracer in asp.net web api.
The type must 'xx' derive from ITraceWriter.\r\nParameter name: service

Solution

The solution of this problem is to specify the ITraceWriter with complete name including namespace. AS there is already a ITraceWriter in the JSON.

config.Services.Replace(typeof(System.Web.Http.Tracing.ITraceWriter), new CustomTracer());

This solves the problem.

Thanks
