This provider enhancement would depend on AWS Lambda generally supporting .NET 8. You can track the progress in the aws-lambda-dotnet repo at aws/aws-lambda-dotnet#1611.

Reference:

• What's new in .NET 8
• Building Lambda functions with C# in AWS Lambda developer guide
• amazon/aws-lambda-dotnet on Docker Hub
• CreateFunction in AWS API reference doc

This suppport is working fine, it just doesn't allow you to specify dotnet8 as a runtime. (e.g., when I deploy using dotnet lamba deploy, everything works)
Can this be updated to reflect the working supported runtime?

Hey All,

The .net 8 runtime for lambda's is available. I think it came out today (the shipped runtime piece). If you go through the aws console - .net 8 is available. Terraform is throwing a validation message with the code above.

I do understand it takes some time to get this change made once its available in AWS. I do appreciate all the hard work that is given to devs through terraform to make deployments of lambda's so easy in .net.

Is there an approximate timeline for this change?

[acwwat]

It looks like .NET support was added in aws-sdk-go-v2 v1.25.1 which was in turn updated in the provider's main branch via #35924 just 11 hours ago. The PR is tagged for v5.38.0 which is the upcoming version. I pulled main to test out the provider in dev mode and I was able to provision a Lambda function with dotnet8 as the runtime successfully. So we should be good with just a bit more patience :)

SAM CLI was updated with dotnet8 support 5 hours ago. Fingers crossed for an update here soon. 😁🤞😁

I was able to get my lambda to run using terraform with runtime= "dotnet8" a few minutes ago.
Provider set at version ">= 5.38.0" (as a test)

Just want to thank everyone for your work on getting this into terraform so quickly after it being released.

Thank you!

This ticket should be closed. 5.38.0 works now.

This ticket should be closed. 5.38.0 works now.

Also confirmed working for me.

Will dotnet 8 support be coming for older versions of this repo? I'm still on 3.x.x and don't particularly want to jump two major versions at once if it can be helped

Currently using 5.15.0 but it is not recognizing dotnet8 as runtime
What's the earliest version it can be used?
