Will RefreshMemoryLimit ship as preview

[normj]

I'm looking into integrating the new RefreshMemoryLimit API into the AWS Lambda .NET runtime. I see the API is marked as preview. Will the API ship as part of .NET 8 as preview? If so I'm uncomfortable updating our production Lambda bootstrapping code to use a preview API. I was really hoping to use this new API to address the issue .NET does not recognize the correct amount of memory inside AWS Lambda.

It would be great if you could confirm this worked for you, with that, I am more than happy to take the preview label off!

I can confirm using preview 7 the APIs work for AWS Lambda's use case. I have a PR out in our repository using the new API and the test pass for .NET 8 and fail for .NET 6. aws/aws-lambda-dotnet#1578

This is the PR to take the preview label off - #91622

Great, thanks! I'll follow the PR. Would the PR make RC1 or is it too late for that?

I don't think so; the last commit to RC1 was two weeks ago.

Thanks, I figured it was too late for RC1 but figured should double check.

@cshung I just test this feature in .NET 8 RC2 and was able to remove my pragma to disable the API preview errors. Thanks!

Also I noticed in the .NET 8 what's new post it talks about this API but it is out of date saying the API is private and requires reflection to call it. I submitted feedback that it was out of date but thought I would let you know as well. https://learn.microsoft.com/en-us/dotnet/core/whats-new/dotnet-8#garbage-collection

Thanks for the notice!

The post should now be updated with dotnet/docs#37474 by @MokoSan, thanks!

If there is a feedback item for that, it should be closed with that PR as well.
