The definition of this report is not valid or is not supported by this version of Reporting Services. The report definition may have been created with a later version of Reporting Services

Hi

I created a blank reportviewer in Visual Studio 2017 but after I added a control I received the error:

ReportProcessingException: The definition of this report is not valid or does not support this version of Reporting Services. The report definition may have been created with a later version of Reporting Services, or it may contain content that is not in the correct format or that is not valid according to the Reporting Services schemas. Details: The report definition has an invalid destination namespace 'http://schemas.microsoft.com/sqlserver/reporting/2016/01/reportdefinition' that can not be updated.

I don't know the configuration to avoid this error.

The unique solution was found in this link..

https://stackoverflow.com/questions/36272514/the-report-definition-has-an-invalid-target-namespace-rsinvalidreportdefinition

But I don't understand this behavior.

In other words... Visual Studio changed:

<Report xmlns="http://schemas.microsoft.com/sqlserver/reporting/2008/01/reportdefinition" xmlns:rd="http://schemas.microsoft.com/SQLServer/reporting/reportdesigner">

 with this code after I edited the report:
<Report xmlns="http://schemas.microsoft.com/sqlserver/reporting/2016/01/reportdefinition" xmlns:rd="http://schemas.microsoft.com/SQLServer/reporting/reportdesigner">
