  I have activate a valid license key on the machine using Visual Studio 2022, Tools → Mescius → License Manager. ASP.NET WebForms latest 2025v2 version.
  
  My project is an ASP.NET WebForms application based on .NET Framework 4.8.1
  
  The licenses.licx file are in Properties subfolder.
  
  The embedded .gclicx file are in the root of project.

  NOT USE ASPX Designer (drag & drop), only manually modifing aspx markup.

  We observed an behavior regarding licenses.licx generation in an ASP.NET WebForms project using C1 controls.

  When the control is added using a manual directive Register in the markup aspx, the licenses.licx file is not updated automatically.

  <%@ Register Assembly="C1.Web.Wijmo.Controls.48"
      Namespace="C1.Web.Wijmo.Controls.C1GridView"
      TagPrefix="cc1" %>
  

  Then, in an .aspx page, we add the control (manually in markup aspx):

  <cc1:C1GridView ID="C1GridView1" runat="server" AutoGenerateColumns="true" />

  Then, its updated Properties\licenses.licx file:

  C1.Web.Wijmo.Controls.C1GridView.C1GridView, C1.Web.Wijmo.Controls.48, Version=4.8.20252.399, Culture=neutral, PublicKeyToken=9b75583953471eea

  Is this behavior expected by design?
  
  Is automatic licenses.licx generation triggered only by the Visual Studio designer?
  
  When controls are added manually in ASPX (my case), is it the developer’s responsibility to maintain licenses.licx manually?

  Thank you for your clarification.

  Hi,

  Yes, in your case, it is the developer’s responsibility to maintain the licenses.licx file manually. However, you do not need to add entries to the file yourself. You can simply use the following option instead:

  Tools → Mescius → Update Projects → Add Missing Entries to the licx File. Select your project and click Update.

  This will automatically add all the required entries to the licenses.licx file based on the C1 DLLs referenced in your project.

  Best Regards,
