CSharp String Array Property setter fails

🐛 Bug Report

What is the problem?

Setting the Connections property on the ConnectionsListProperty in the Glue module with a valid string array fails to synthesize with the following error:

System.ArgumentException: Could not convert value ‘System.Collections.Generic.Dictionary`2[System.String,System.Object]’ with unrecognized type

Reproduction Steps

            var job = new Amazon.CDK.AWS.Glue.CfnJob(this, "testJob",  
                new CfnJobProps {
                    Name = "test",
                    GlueVersion = "1.0",
                    Role = "TestingGlueRole",
                    MaxCapacity = 4,
                    Connections = new ConnectionsListProperty
                    {
                        Connections = new string[1] { "AcmeData-test1" }
                    }
            });
