AWS Lambda now fully supports .NET 6, but this isn't mentioned in the AWS Lambda Deploy Function task yet. If you select the "Update code and configuration (or create a new function)" option you can only select dotnetcore3.1 and dotnetcore2.1 in the Runtime dropdown. Since .NET 6 is the new LTS for .NET Core it makes sense that the option for the .NET6 runtime is there as well.
