Applications that are created using ASP.NET Core Web API services require a unique license key. These licenses are bound to specified applications and are to be validated at runtime. Licenses are added to the applications by generating the same using runtime licensing add-in on Visual Studio. The add-in for generating Run-time License is available in all applications using ASP.NET Core Web API.

License key for the ASP.NET Core Web API applications created on Visual Studio is generated through GrapeCity License Manager add-in provided in Visual Studio.

If you are generating a evaluation license, your application is now ready to use for evaluation purposes. You can repeat this process for any number of applications. You must generate a new evaluation license for each application because they are unique to the application name.
