Why was the assignment of activity.DisplayName changed from HttpRequest.Path to HttpRequest.Method?

[wzl-bxg]

Is it a bug that the assignment of activity.DisplayName is changed from HttpRequest.Path to HttpRequest.Method when I use the netstandard2.0 version of OpenTelemetry.Instrumentation.AspNetCore, while in the older version before1.6 it was obtained from HttpRequest.Path?

When I use this library in my .NET Core 3.1 project, all exported activities have DisplayName set as Post and Get, which is not what I want.

before1.6：

1.7 and newer:

@wzl-bxg - It is not a bug. Activity.DisplayName by default gets set to http method if the route information is not available. This is as per the specification

Using the instrumentation library with .NET Core 3.1 isn't a supported scenario. .NET Core 3.1 has reached end of life https://dotnet.microsoft.com/en-us/download/dotnet/3.1 and you should upgrade to latest supported version.
