.NET CDK 1.8 ClusterEndpoint does not return port number

Like with #2711, .NET CDK 1.8 DatabaseCluster.ClusterEndpoint.Port is of type double, precluding getting endpoint port back. The workaround described in #2711 can be used to mitigate the issue.

Reproduction Steps

Use .NET CDK 1.8 to create RDS Aurora cluster.

Error Log

Environment

• CLI Version :1.8
• Framework Version: .NET Core 2.1
• OS :WIndows 10
• Language :.NET C#

This is 🐛 Bug Report

In case anyone else ends up in this question, the mystery number comes form the numeric Token representation: https://docs.aws.amazon.com/cdk/latest/guide/tokens.html

To solve this in my case, I used the cdk.Token class to convert the numeric Token into a string Token:

environment: {
    DB_PORT: cdk.Token.asString(props.rdsICluster.clusterReadEndpoint.port),
},

This synthesizes as "Fn::ImportValue": "FoobarInfra:ExportsOutputFnGetAttDatabaseB269D8BBEndpointPort3ACB3F51", which ends with the correct value in the ECS Task Container.

It’s a nice workaround, @marioizquierdo, thank you, but it also shows the problem is still there and the issue needs trip be reopened @RomainMuller.
