c# - 客户端和服务之间存在类型不匹配。更新azure存储后出现错误

Question

这个错误给我的工作带来了很大的延误。
当我升级 nuget 软件包(尤其是 Windows Azure Storage)时，就会发生这种情况。

然后当我运行云项目时，它给了我这个错误:

Server Error in '/' Application.

There is a type mismatch between the client and the service. Type '[ProjectNamespace].Merchants.DeviceRegistration' is not an entity type, but the type in the response payload represents an entity type. Please ensure that types defined on the client match the data model of the service, or update the service reference on the client.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

我完全不知道如何找到解决方案。

这是更高版本:

我还注意到更高版本会生成以下查询:

{https://[accountname].table.core.windows.net/MerchantApplication()?$filter=(PartitionKey eq '635180925195321704_38913b36f10d47e4916671ba51e2184c') and (RowKey eq 'D_f974c1da570946f183f4f4640534a343')}

为了添加更多信息，我还执行了以下操作:

• 删除所有nuget包并一一恢复
• 更新了 nuget.exe 以及所有 nuget 包，我什至更新了 Windows Azure Tools for Visual Studio 2012。版本为 2.2
• 我已经尝试了在网上找到的与此问题相关的所有可能的解决方案。

但最终上述问题并没有得到解决。
现在，我回到之前的项目文件。但是这个项目在部署到生产服务器(Windows Azure)时遇到问题，但在临时服务器中却没有。确实很奇怪。

参见here寻找对我有用的答案。

基本上，添加一个DataServiceKey归因于您的TableEntity包含 Merchants.DeviceRegistration 的派生类( PartitionKey ？)和RowKey特性。

我想你的类声明需要如下所示:

[DataServiceKey("PartitionKey", "RowKey")]
DeviceRegistration : TableEntity
