I try to use CDK to create AWS monitoring dasboard and crash on running cdk synth command

Reproduction Steps

internal DashboardStack(Construct scope, string id, IStackProps props = null) : base(scope, id, props)
        {
            var dashboard = new Dashboard(this, "MonitoringDashboard", new DashboardProps
            {
                DashboardName = "MonitoringDashboard"
            });
 
            dashboard.AddWidgets(BuildWidget("dev", "Invocations", "Sum"));
        }

        private GraphWidget BuildWidget(string env, string metricName, string statistic)
        {
            IMetric metric = new Metric(new MetricProps
            {
                Namespace = "AWS/Lambda",
                Region = Region,
                Account = Account,
                Label = "functionName",
                MetricName = metricName,
                Dimensions = new Dictionary<string, object>(1) { { "FunctionName", "functionName" } },
                Statistic = statistic
            });
            var graphWidgetProps = new GraphWidgetProps
            {
                Title = metricName,
                Region = Region,
                Left = new [] { metric }
            };
            return new GraphWidget(graphWidgetProps);
        }

Found the cause of this issue, definitely a jsii bug (I have a fix but I'm trying to qualify the bug more cleanly so I can have a nice regression test for this condition).

fix(dotnet): "Could not infer JSII type for .NET type 'AnonymousObject'"
c4552a9 
When obtained through an untyped way (e.g: as part of an opaque object
for example), instances of `AnonymousObject` could not be cast back to
their Kernel form, because the converter lacked a code path to handle
this type. Instead, it insisted on trying to infer a "better" run-time
type for it.

This adds the necessary code path to handle this condition and properly
return the reverse conversion.

Fixes aws/aws-cdk#7977
