CSharp String Array Property setter fails

[rschiefer]

🐛 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" }
                    }
            });

@rschiefer Welcome to the club of #3244 !

I'm also experiencing the original issue with Amazon.CDK 1.7.0-devpreview (and Amazon.JSII.Runtime 0.16.0).

var role = new Role(this, "rolepatterns", new RoleProps { RoleName = "rolepatterns", AssumedBy = new Amazon.CDK.AWS.IAM.ServicePrincipal("lambda"), ManagedPolicies = new[] { ManagedPolicy.FromAwsManagedPolicyName("service-role/AWSLambdaSQSQueueExecutionRole") }, InlinePolicies = new Dictionary<string, PolicyDocument> { { "AllowSNSPublish", new PolicyDocument( new PolicyDocumentProps { Statements = new [] { new PolicyStatement( new PolicyStatementProps { Effect = Effect.ALLOW, Actions = new[] { "sns:Publish" }, Resources = new[] { "*" } }) } }) } } });
