Method not found: 'Amazon.CloudWatch.EMF.Logger.MetricsLogger Amazon.CloudWatch.EMF.Logger.IMetricsLogger.PutMetric(System.String, Double, Amazon.CloudWatch.EMF.Model.Unit)'

[Dave-EMIS]

We are using :

• Amazon.CloudWatch.EMF 2.1.0
• Amazon.CloudWatch.EMF.Web 1.0.0
• ASP.NET Core 6.0 / .NET 6.0

I then add UseEmf and UseEmfMiddleware we are getting the following error when making any call to our API:

An unhandled exception has occurred while executing the request.
System.MissingMethodException: Method not found: 'Amazon.CloudWatch.EMF.Logger.MetricsLogger Amazon.CloudWatch.EMF.Logger.IMetricsLogger.PutMetric(System.String, Double, Amazon.CloudWatch.EMF.Model.Unit)'.

This looks to be caused by #48

It should be resolved just by rebuilding and publishing the .Web against 2.1.0.

I've worked around the issue by just copying the source for the .Web package into my codebase.
