+# .NET Core Design-Time Features
+
+## Overview
+
+We have expanded design-time support—such as Smart Tags, Custom Collection Editors, and Custom Forms for UITypeEditor—to include controls targeting .NET 6 and higher, which were previously available only in the .NET Framework.
+
+## Why We Use the WinForms Designer SDK
+Microsoft has introduced the **WinForms Designer SDK** NuGet package to support custom design-time experiences in Visual Studio for .NET Core and later versions. This SDK replaces the traditional designer APIs that were previously part of the .NET Framework and Windows OS.
+
+The new Designer SDK offers several key advantages:
+
+* Independent of the operating system
+* Not reliant on the .NET Framework
+* Fully integrated with Visual Studio
+
+It provides essential extension points and base classes that allow developers to implement advanced design-time features such as, **Smart Tags, Custom Collection Editors, Custom Forms for UITypeEditor**.
+
+These features are now available for controls targeting .NET 6 and higher.
+
+To enable this functionality, we have included the **WinForms Designer SDK** as a dependency in our control NuGet packages starting from this version **v26.1.35**. This ensures a consistent and enhanced design-time experience across modern .NET platforms.
+
+## Control Package Details
+We have added the **WinForms Designer SDK** as a dependency in the following control packages. Please refer to the table below for details:
