NuGet Package for Telerik UI for ASP.NET AJAX Not Visible in Visual Studio

Updated on Jul 24, 2026

Description

I have an active license, but still I cannot find the required version of the NuGet package for Telerik UI for ASP.NET AJAX (e.g., Telerik.Web.UI.dll >= 2026.2.708 (2026 Q2 SP1)) in the NuGet Package Manager within Visual Studio. I am trying to upgrade, but the desired package is not showing.

Cause

Starting with release 2024.2.513 (2024 Q2), the minimum supported .NET Framework version for Telerik UI for ASP.NET AJAX changed to .NET Framework 4.6.2. The Telerik.UI.for.AspNet.Ajax.Net45 package, used for .NET Framework 4.5 projects, is no longer supported or available for newer versions. The updated package is named Telerik.UI.for.AspNet.Ajax.Net462.

Solution

To resolve the issue, switch to the package compatible with .NET Framework 4.6.2 by following these steps:

1. Uninstall the Telerik.UI.for.AspNet.Ajax.Net45 package from your project.
2. Search for the Telerik.UI.for.AspNet.Ajax.Net462 package in the NuGet Package Manager in Visual Studio.
3. Install the Telerik.UI.for.AspNet.Ajax.Net462 package. This package includes the desired version 2026.2.708 (2026 Q2 SP1).

Ensure that your project targets .NET Framework 4.6.2 or a later version before installing the updated package.
