var endPoint = "https:/endpoint-URI:443/";
var key = "api-Key";

CosmosClient cosmosClient = new CosmosClient(endPoint,key); // i get error here
var databaseName = "dbName";
var containerName = "containerName";
var container = cosmosClient.GetContainer(databaseName, containerName);
var upsertOrder = new
{
id = new Guid(),
Partition = "",
Ticker = "ABC"
};
var response = await container.CreateItemAsync(item: upsertOrder)

Я должен иметь возможность инициализировать доступ клиента Cosmo к данным
