A The type or namespace name 'Telerik' could not be found (are you missing a using directive or an assembly reference?) error occurs on build.
The possible reason for this issue is that Telerik assemblies are not properly referenced or updated.
Double-check if the project has references to Telerik Reporting assemblies and if CopyLocal is set to true in the Visual Studio Property grid. If you have recently updated your Telerik Reporting installation, run the [Upgrade Wizard]({%slug telerikreporting/designing-reports/report-designer-tools/desktop-designers/visual-studio-report-designer/upgrade-wizard%}) in all related projects in Visual Studio.
If Telerik Reporting assemblies are referenced and updated, verify that the project targets the .NET4+ Framework Full Profile version.
