Issue details

.NET 8 added support for collection expression and also added an annotation CollectionBuilder I think there are many places the Pulumi .NET code could use these to improve code syntax :)

Especially for things like GetPolicyDocuments and Statements in AWS 🤔

You can get pretty close if you're willing to change your signature, by declaring the signature on the left side which seems to be the requirement for Collection Expression.

SecurityGroupIngressArgs[] ingress =
[
    new()
    {
        Protocol = "tcp",
        FromPort = 80,
        ToPort = 80,
        CidrBlocks = new[] { "" },
    },
];

var securityGroup = new SecurityGroup($"server-{suffix}-security-group", new()
{
    Name = $"server-{suffix}-security-group",
    VpcId = accountRegion.VpcId,
    Ingress = ingress,
});

The signature that is currently not supported although based on types it could be inferred. I am not sure if it is a compiler limitation or Pulumi limitation with the InputList types:

Egress = [
    new()
    {

    }
],

Neither is this supported:

Egress = [
    new SecurityGroupIngressArgs()
    {

    }
],
