Looking on the question title I think you have problem with using statement and IDisposable interface.
C# by default provides IDisposable interface that can be used to release some resources (unmanaged resources). Classes that implement IDisposable intereface may be used with using statement that releases resouces automatically when the using statement execution is ended.
But your CommonLogger class implements your own IDisposable interface that you want to use later in using (ILogger logger = new CommonLogger(loggers)). The solution for the Error CS1674 is to remove your IDisposable interface and use the one provided by .NET.
