使用Microsoft.Azure.Storage（cosmosDB）更新表对象失败

Question

I cannot update table objects using using Microsoft.Azure.CosmosDB.Table and get the following exception. "Message: The requested resource is no longer available at the server." Code: Gone I can run selects without issue.

Using namespace Microsoft.WindowsAzure I can do queries and updates. Also this code works against devdb storage or if I change connection string to Azure Table storage. The only thing that does not work is pointing to CosmosDb.

`

Microsoft.Azure.Storage;
using Microsoft.Azure.CosmosDB.Table;

namespace AzureTester
{
class Program
{
    static void Main(string[] args)
    {
        //cosmosdb.azure these don't work for TableOperation.InsertOrMerge(x).  They do for Selects
        var connectionString = "........TableEndpoint=https://*****.table.cosmosdb.azure.com:443/;";

        //table storage or dev this works for everything
        //var connectionString = ".....EndpointSuffix=core.windows.net";
        //var connectionString = "UseDevelopmentStorage=true;";

        var storageAccount = CloudStorageAccount.Parse(connectionString);
        CloudTableClient tableClient = storageAccount.CreateCloudTableClient();
        var table = tableClient.GetTableReference("Boat");

        TableQuery<Boat> query = new TableQuery<Boat>()
            .Where(TableQuery.GenerateFilterCondition("PartitionKey", QueryComparisons.Equal, "jack"));

        var returnedBoat = table.ExecuteQuerySegmentedAsync<Boat>(query, null).Result; //this always works.

        Boat x = new Boat();
        x.PartitionKey = "jack";
        x.RowKey = "black";
        x.Type = "dragon";
        TableOperation insertOrMergeOperation = TableOperation.InsertOrMerge(x);
        //hangs on this line when connection string is cosmosdb.azure.com
        TableResult result = table.Execute(insertOrMergeOperation);
        Boat inserted = result.Result as Boat;
    }

Answer 1

When Cosmos DB Table API came out, I think they used the namespace Microsoft.Azure.Storage, but they now use Microsoft.Azure.CosmosDB.Table. Also, from your code, it's not clear if you want to access Cosmos DB Tables or Azure Storage Tables. If you want to access Azure Storage Tables, you must use the WindowsAzure.Storage.* assemblies, and you will access the storage account.

If you want to access the data in a CosmosDB Table, you have to use their Table API, and the data has to be in a Cosmos DB database, not in Azure Storage. For an example of using .NET to access a Cosmos DB table, see Quickstart: Build a Table API app with .NET and Azure Cosmos DB .

Try using version 8.6.0 or 8.7.0 of Microsoft.Azure.Storage.Common

Uninstall Microsoft.Azure.CosmosDB.Table.1.1.0. Then uninstall Microsoft.Azure.Storage.Common.9.0.0.1-preview. Then install Microsoft.Azure.Storage.Common.8.6.0-preview or Microsoft.Azure.Storage.Common.8.7.0.1-preview. Then finally install Microsoft.Azure.CosmosDB.Table.1.1.0.

The failure is caused by something on my local pc/network. I suspect McAfee Endpoint Security similar to this post: Azure DocumentDB sporadically throws SocketException / GoneException

The same code functions fine from my home PC. Although I've not identified the exact fault its likely to be antivirus or firewall protection.

I've no explanation as to why McAfee allows Microsoft.WindowsAzure and not Microsoft.Azure
