Hello Yogesh, I have modified the code and made it works. Please refer to the GitHub URL "https://github.com/vishipayyallore/speaker_series/tree/master/Azure/Simple.CosmosDbDemo". Code: class Program { private static IConfiguration _config; static async Task Main( string [] args) { _config = new ConfigurationBuilder() .SetBasePath(Directory.GetCurrentDirectory()) .AddJsonFile( "appsettings.json" ) .Build(); string databaseName = _config[ "CosmosDbConnection:DatabaseName" ]; string containerName = _config[ "CosmosDbConnection:ContainerName" ]; CosmosClient client = await InitializeCosmosClientInstanceAsync().ConfigureAwait( false ); DatabaseResponse database = await client.CreateDatabaseIfNotExistsAsync(databaseName); await database.Database.CreateContainerIfNotExistsAsync(containerName, "/id" ); Console.WriteLine( "

Press any key ..." ); Console.ReadKey(); } private static async Task InitializeCosmosClientInstanceAsync() { string account = _config[ "CosmosDbConnection:Account" ]; string key = _config[ "CosmosDbConnection:Key" ]; CosmosClientBuilder clientBuilder = new CosmosClientBuilder(account, key); CosmosClient client = clientBuilder .WithConnectionModeDirect() .Build(); return await Task.FromResult(client); } } AppSettings: { "CosmosDbConnection" : { "Account" : "https://YourAccount.documents.azure.com:443/" , "Key" : "YourAccountKye" , "DatabaseName" : "YourDatabaseName" , "ContainerName" : "YourContainerName" } }

Hello Yogesh, I got it now. Could you please paste the appsettings.json? PLEASE remove the secrets and other information before pasting it here. I want to check the structure of the .json. Many thanks.

Hello Yogesh, Good morning. Few queries. 1. Are you connecting to Local Cosmos Db? OR Azure Cosmos Db? 2. Could you please paste the code inside "InitializeCosmosClientInstanceAsync" method? 3. Let me try replicating on my box. Many thanks. Regards, Swamy
