Description

How to add the license script key file in your project, when Telerik WPF components are loaded through a CPP/C++ project.

Solution

In this case, you should add a TelerikLicense.cs file in the C# project that defines the Telerik controls and another TelerikLicense.cpp file in the CPP project that loads the Telerik-related code.

xml

    <ClCompile Include="TelerikLicense.cpp" />

The content of the TelerikLicense.cpp file should look like this:

cpp

    #include "pch.h"
    using namespace Telerik::Licensing;
    [assembly:EvidenceAttribute("  <my key>  ")];
