Need Help Updating? Check Out the .NET Framework WinForms Update Utility
In 2025 v2, we introduced some breaking changes as we consolidated our .NET Framework and .NET Platform (i.e., .NET 10) packages to support multi-targeting. This change impacts developers who still target .NET Framework 4.8 and need to update to the latest version (2025 v2 or later).
To help with this update process, you can download the WinForms Migration Utility, which automatically updates your .NET Framework applications to the latest version of the ComponentOne WinForms libraries.

The utility automatically handles package and namespace changes, saving you a lot of time if you have many forms with designer-generated code.

Data Services 2026 v1.1 Updates
We’ve added the IsTrimmable attribute across most ComponentOne Data Service components, including C1DataCollection and all data connectors. The attribute is now available for .NET 7 and higher. Trimming is a process that reduces the size of self-contained applications by removing unused code. This property is particularly useful for library authors who want to ensure their libraries are optimized for trimming scenarios.
