将Visual Studio 2015更改为Visual Studio 2017后，RDLC报告停止工作

我在Visual Studio 2017中有一个AspNet MVC项目，该项目以前是在Visual Studio 2015中开发的.该项目包含许多 rdlc文件，在我编辑其中一个之前，它们一直可以正常工作.现在，当我尝试从编辑的rdlc下载pdf时，出现此错误:

I have an AspNet MVC project in Visual Studio 2017 that was previously developed in Visual Studio 2015. This project contains many rdlc files that were working fine until I edited one of them. Now, when I try to download the pdf from the rdlc edited I get this error:

此报告的定义无效或不支持 版本的Reporting Services.该报告的定义可能是 使用更高版本的Reporting Services创建或包含内容 根据Reporting Services格式不正确或无效的文件 模式.详细信息:报告定义的目标无效 命名空间 ' http://schemas.microsoft.com/sqlserver/reporting/2016/01/报告定义" 无法升级.

The definition of this report is not valid or supported by this version of Reporting Services.

Details: The report definition has an invalid target namespace 'http://schemas.microsoft.com/sqlserver/reporting/2016/01/reportdefinition' which cannot be upgraded.

编辑的rdlc从 http://schemas.microsoft.com更改其名称空间/sqlserver/reporting/2008/01/reportdefinition 到 http://schemas.microsoft.com/sqlserver/reporting/2016/01/reportdefinition

该项目在 net Framework 4.6.2 上运行，并且已安装 Microsoft.ReportViewer.Runtime.Common.12.0.2402.15 和 Microsoft.ReportViewer. Runtime.WebForms.12.0.2402.15 nuget程序包
