Is this change really required? We would like to use OpenTelemetry from a legacy ASP.NET forms application, and due to some legacy issues we cannot bring in Microsoft.Extensions.Options (or any other .NET Extensions package) newer than 3.1. Previous minor version packages used 3.1:

• OpenTelemetry 1.6 uses Microsoft.Extensions.Logging.Configuration (>= 3.1.0)
• OpenTelemetry.Api.ProviderBuilderExtensions 1.6 uses Microsoft.Extensions.DependencyInjection.Abstractions (>= 3.1.0)

@srogovtsev What's the issue that prevents you from bumping the M.E.* packages? Is it this thing with InplaceStringBuilder being removed from Microsoft.Extensions.Primitives? If that is the case FYI it seems to have been fixed in v8: dotnet/runtime#85846

[srogovtsev]

@CodeBlanch , it's exactly that! Thank you for the information, we'll see if we can use this to our advantage!

I just wanted to follow up by saying that preliminary results show everything working for us with M.E 8, which is so an unexpected relief. We've been trying to upgrade for some years.

@CodeBlanch , thanks again oh-so-much for this hint.
