C# 在我的基于VB的网站中同步SQL Server 2014和SQL Server 2014 Express数据库问题.net 4.0不支持此类接口

我已在IIS 10和Window10（x64）上设置了我的网站，并在我的网站中引用了SQL Server 2014 Express RMO库，但我收到一个错误：

Microsoft.SqlServer.Replication.Com错误异常：“不支持此类接口”

当我打电话给

Microsoft.SqlServer.Replication.MergeSynchronizationAgent.Synchronize()  

方法。我遵循了示例中定义的相同代码

// Define the server, publication, and database names.
string subscriberName = subscriberInstance;
string publisherName = publisherInstance;
string distributorName = distributorInstance;
string publicationName = "AdvWorksSalesOrdersMerge";
string subscriptionDbName = "AdventureWorks2012Replica";
string publicationDbName = "AdventureWorks2012";
string hostname = @"adventure-works\garrett1";
string webSyncUrl = "https://" + publisherInstance + SalesOrders/replisapi.dll";


// Create a connection to the Subscriber.
ServerConnection conn = new ServerConnection(subscriberName);

MergePullSubscription subscription;
MergeSynchronizationAgent agent;

try
{
    // Connect to the Subscriber.
    conn.Connect();

// Define the pull subscription.
subscription = new MergePullSubscription();
subscription.ConnectionContext = conn;
subscription.DatabaseName = subscriptionDbName;
subscription.PublisherName = publisherName;
subscription.PublicationDBName = publicationDbName;
subscription.PublicationName = publicationName;

// If the pull subscription exists, then start the synchronization.
if (subscription.LoadProperties())
{
    // Get the agent for the subscription.
    agent = subscription.SynchronizationAgent;

    // Check that we have enough metadata to start the agent.
    if (agent.PublisherSecurityMode == null)
    {
        // Set the required properties that could not be returned
        // from the MSsubscription_properties table. 
        agent.PublisherSecurityMode = SecurityMode.Integrated;
        agent.DistributorSecurityMode = SecurityMode.Integrated;
                 agent.Distributor = publisherName;
                 agent.HostName = hostname;

        // Set optional Web synchronization properties.
        agent.UseWebSynchronization = true;
        agent.InternetUrl = webSyncUrl;
        agent.InternetSecurityMode = SecurityMode.Standard;
        agent.InternetLogin = winLogin;
        agent.InternetPassword = winPassword;
    }
    // Enable agent output to the console.
    agent.OutputVerboseLevel = 1;
    agent.Output = "";

    // Synchronously start the Merge Agent for the subscription.
    agent.Synchronize();
}


else
    {
        // Do something here if the pull subscription does not exist.
        throw new ApplicationException(String.Format(
            "A subscription to '{0}' does not exist on {1}",
            publicationName, subscriberName));
    }
}
catch (Exception ex)
{
    // Implement appropriate error handling here.
    throw new ApplicationException("The subscription could not be " +
        "synchronized. Verify that the subscription has " +
        "been defined correctly.", ex);
    }
    finally
    {
        conn.Disconnect();
    }

您是否遵循了以下网站中的所有步骤？是否从VisualStudio菜单项目中添加了库：添加引用？您可以在“参考”下的“解决方案资源管理器”中进行验证。我遵循了那篇文章中定义的相同步骤，我认为对发布服务器、分发服务器和订阅服务器的SQL server版本支持是有意义的。因为我已经用SQL server 2016标准和SQL express 2014版本对其进行了测试。工作正常。但是，SQL server 2014标准和SQL express 2014没有提供此类接口支持问题。有一个2014版的msdn网页：。所以我不认为这是一个版本。您使用的是Standard还是Express？Express并没有所有的功能。你可能错过了一个图书馆。您是在working case中使用NET4.0还是更高版本？您可能需要发布应用程序并在IIS上安装，IIS将获取缺少的dll（其中包含库）并使用缺少的库更新IIS。我有版本为12.0.5589的sql server 2014标准，以及版本为x64位的sql express 2014 v 12.0.5589的相同标准。我遵循了文章中描述的所有步骤。当我在客户端或windows控制台应用程序上使用web应用程序中的RMO调用它时，调用代理.synchronize（）方法时都会出现“不支持此类接口”错误。我不是SQL授权方面的专家。我认为发生的是，您的标准没有正确安装许可证，因此默认为express options。见：
