Hello,
I used VS 2019 and Report Viewer is 12.0.SQL Server 2014 .
I encounter the following error after modifying a report RDL in Report Builder.
System.Web.Services.Protocols.SoapException: The definition of this report is not valid or supported by this version of Reporting Services. The report definition may have been created with a later version of Reporting Services, or contain content that is not well-formed or not valid based on Reporting Services schemas. Details: The report definition has an invalid target namespace'http://schemas.microsoft.com/sqlserver/reporting/2016/01/reportdefinition' which cannot be upgraded.*
Please help me how to fix it.!
