GetChangeFeedProcessorBuilder is inaccessible due to its protection level

We are continuously addressing and improving the SDK, if possible, make sure the problem persist in the latest SDK version.

Describe the bug The compiler complains that the method “GetChangeFeedProcessorBuilder” is inaccessible in Azure.Cosmos version 4 preview 3.

To Reproduce

1. dotnet add package Azure.Cosmos --version 4.0.0-preview3

CosmosClient cosmosClient = new CosmosClient(EndpointUrl, AuthorizationKey);
container.GetChangeFeedProcessorBuilder<object>(processorName: "changeFeedSample", onChangesDelegate: HandleChangesAsync)
  .WithInstanceName("consoleHost")
  .WithLeaseContainer(leaseContainer)
  .Build();

Expected behavior Either the compiler should not complain or the docs should mention which method to use in the latest version.

Actual behavior The compiler doesn’t let the code be compiled.

Environment summary SDK Version: Azure.Cosmos 4.0.0-preview3 .Net Version: 6.0.101 OS Version: Windows 10 (Ubuntu 20.04 LTS using WSL)

Maybe I expressed myself wrong. When I said “There is a reason why it is still in preview” I was admitting that @bartelink is right and that I understand that V4 wouldn’t work in some scenarios. When I rereaded it I realized I sounded like I was criticizing the fact that to this day it is still in preview, but that is NOT what I meant. Sorry for that.

There is a reason why the V4 is still in preview

I would put it differently - the V4 preview is/was a spike.

Still, I thought it would be helpful to report this problem.

Far more useful to clarify whether the problem you cite exists on V3 (and/or what you are proposing; it’s not obvious to me from the OP) - the next V4 type thing will be based off master in this repo in order to take in all the features and fixes in the two years since then.
