how can we assign vpcid while creating a ecs service under ecs cluster through .net aws sdk?

Hi Team,

I have created a ECS TaskDefinition then I am creating a ecs cluster. Inside cluster I want to create a service through .net awssdk 2.3.55.2 classes. But I am not able to set vpcid under NetworkConfiguration or AwsVpcConfiguration class. Our code is automatically assigning very first vpcid while creating ecs service. Can you please suggest how can I assign/set vpcid which we require instead of selecting first entry from vpc list? Due to this issue my websites are not launching on containers as containers/service doesn't have correct vpcid assigned. Thanks
