I will post my question in this thread to not pollute the forums with all my problems.
First, the wpf component reportviewer is not enabled in my solution :(
During the installation of the trial, i first unchecked the 'visual studio integration' because in general i prefer to keep my visual studio installation as light as possible, but may be it's reason of my problem.
I've added the following reference to my project: Telerik.Reporting.dll, Telerik.Reporting.Wpf.dll and Telerik.ReportViewer.Wpf.Themes (all 3 are pointing on the 2019 trial installation)
But when in my Xaml, i start to write
or <telerik:Report the intellisense finds nothing.
There are already some telerik components on the test window but they are 2017 Telerik IU for wpf and the namespace currently declared is this one: xmlns:telerik="http://schemas.telerik.com/2008/xaml/presentation"
So, i made a try by using the Component Toolbox, but of course because of my choice during the installation, no telerik's components are registered. So i restart the Telerik Reporting installer and check the 'visual studio integration', but the toolbox stay empty.
So, i try to follow the procedure written there : https://docs.telerik.com/reporting/wpf-report-viewer-manual-setup#how-to-add-the-wpf-reportviewer-to-the-toolbox
But, the Telerik.ReportViewer.Wpf assembly is not listed in the components (i can see all the telerik UI for wpf ones but none for reporting). If i try to use the Browse button to select the Telerik.ReportViewer.Wpf in my fresh installation of TelerikReporting, i have an error message saying :'There are no components in 'C:\Program Files (x86)\Progress\Telerik Reporting R1 2019\Bin\Telerik.ReportViewer.Wpf.dll' that can be placed on the toolbox.'
Ok it seems i have messed up my installation or there's something i don't understand.
What can i do ?
