I recently downloaded your telerik studio and i simply create a WPF application in VS2015 with framework 4.6 as target framework.
Then i drag and drop a control and checked the assembly version for the telerik assemblies added under Reference section. All it shows 4.5 framework version.
Is telerik provides 4.5.1 and 4.6 .net framework control for VS2015? Am asking about toolbox support.
Is there any telerik documentation to know about VS2015 toolbox support in detail?
