Cosmosdb Bind in Azure Functions Local

Question

How to bind Azure Cosmodb to Visual Studio in Azure Functions?

Note the code below, the inputDocument parameter would be the Cosmosdb Bind. When we create Funcão direct in the Azure portal, it already does this automatically because it already creates the connections in the file local.settings.json.

using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Host;
using System.Collections.Generic;

    namespace CDPCompare
    {
        public static class CallWS
        {
            [FunctionName("TimerTriggerCSharp")]
            public static void Run([TimerTrigger("0 */5 * * * *")]TimerInfo myTimer, TraceWriter log, IEnumerable<dynamic> inputDocument)
            {
                foreach(var item in inputDocument)
                {
                    log.Info(item);
                }
            }
        }
    }

To bind to a Function you need to add the following configuration:

1 - Install the Nuget package Microsoft.Azure.WebJobs.Extensions.DocumentDB

2 - Include the attribute [DocumentDB("%DatabaseName%", "MyCollection")] followed by the parameter IEnumerable<dynamic> inputDocuments

3 - Add the Cosmosdb connection string to the file local.settings.json "AzureWebJobsDocumentDBConnectionString":"STRING DE CONEXÃO COSMOS DB"
