The report definition is not valid. Details: The report definition has an invalid target namespace的问题依旧可以用如下方式解决
Web:
Install-Package Microsoft.ReportingServices.ReportViewerControl.WebForms
WinFrom:
Install-Package Microsoft.ReportingServices.ReportViewerControl.WinForms
此时winform的工具箱依旧没有对应的ReportViewer控件,打开当前项目下packagesMicrosoft.ReportingServices.ReportViewerControl.Winforms.140.1000.523lib et40,把Microsoft.ReportViewer.WinForms.dll拖到工具栏内即可,So easy~
