Telerik | App_Licenses.dll | ASP.NET application

 "Telerik app_Licenses.dll" is a file used to store license information for Telerik UI components within an ASP.NET application, essentially acting as a verification mechanism to ensure that you are using a purchased, valid license for the Telerik controls in your project, preventing trial limitations or copyright messages from appearing in your deployed application. 

Key points about app_Licenses.dll:

• Function:

  This DLL contains details about your Telerik license, allowing the application to check if you have a valid license to use the Telerik controls commercially.
• How it works:

  When you include Telerik controls in your project, the application automatically checks the information within this file to determine if you are authorized to use the controls.
• Trial vs. Licensed:

  If you are using a trial version of Telerik, the application might display trial limitations or copyright messages, but once you purchase a license and update the app_Licenses.dll file, these limitations should be removed. 

Important considerations:

• Deployment:

  While this file is crucial for development and testing, it is typically not directly deployed to a production server as the license information is embedded within the DLLs themselves.
• Location:

  You can usually find the app_Licenses.dll file in the root directory of your web application.
