C＃ASP.NET，Azure混合sql连接无法连接到Web窗体应用程序上的数据库

Question

我们公司想部署一个Web窗体应用程序，但仍然在本地运行我们的数据库。 Azure混合连接可让您执行此操作。我已经创建了一个新项目，并遵循Microsoft Azure的this。

该应用程序在调试时工作，我可以将新用户添加到数据库并登录。应用程序在部署时运行，但是当我想登录或向成员数据库添加新用户时，它会给我：“算术操作导致溢出“。

web.config中的ConnectionString：

<add name="DefaultConnection" connectionString="Server=MyServerName\\MAILREGLOCAL,1433; Database=MembershipDB; User ID=myID; Password=myPassword" 
    providerName="System.Data.SqlClient" /> 

以下是完整的堆栈跟踪：

哇，没想到的是 - 感谢亚拉文指着我this site。

什么固定的问题是继从MSDN这些说明：

**

The instructions need to be followed on hosts running the Hybrid Connection Manager. The instructions for directly editing the registry are: 
To add this schannel registry entry registry entry, follow these steps: 
1.Click Start, click Run, type regedit in the Open box, and then click OK. 
2.Locate and then click the following subkey in the registry: 
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\SecurityProviders\SCHANNEL 
3.On the Edit menu, point to New, and then click DWORD Value. 
4.Type SendExtraRecord for the name of the DWORD value, and then press Enter. 
5.Right-click SendExtraRecord, and then click Modify. 
6.In the Value data box, type 2 to disable the split record in schannel, and then click OK. 
7.Exit Registry Editor. 
8. Restart the Azure Hybrid Connection Manager Service or reboot the machine the Azure Hybrid Connection Manager Service is installed on (see the security update to determine which is required, or reboot the machine to be safe) 
Make sure that if you copy/paste the key name you don’t accidentally put a space in at the end. 
Make sure you name the DWORD “SendExtraRecord” 
Make sure the DWORD was set to 2.
