I am Microsoft Rdlc Report Designer extension and NuGet ReportViewerControl.Winform
package.
Now it is possible to open *.rdlc file in Visual Studio 2017 designer, but when i try to save my report i am getting error: "Unknown Report Version: 9.0
Also, i can't create empty *.rdlc file because don't have the same template in New File... dialog
UPD:
At this
moment, i have no idea how to fix that, but i know hwo to avoid it:
Open your old
report in VS2015 and then save it - next time VS2017 can open/edit/save files.

:
This happens when you have missed a reference. Please search through all of your code and project files to find the 9.0 references and update to 14.0.

It means that you need to search for patterns (previous xml structure) of 9.0 version in your *.rdlc file, which was not obvious for me.
That is why resave in VS2015 worked.
