How to Update ComponentOne WPF Controls to .NET Framework 4.6.2

Microsoft is frequently upgrading .NET Framework, including enhancements, bug fixes, security fixes, and many more. To keep up with Microsoft and allow our customers to work with the latest technologies, we have introduced ComponentOne WPF controls for .NET Framework 4.6.2. So, if you are using ComponentOne WPF .NET Framework 4.5.2 controls, this article is worth reading.

In this article, we will see how to upgrade ComponentOne WPF controls from .NET 4.5.2 to .NET 4.6.2.

Why Migrate to 4.6.2?

The .NET Frameworks (4.5.2, 4.6 & 4.6.1) were digitally signed by SHA-1 supporting certificate, which is no longer secure; therefore, Microsoft is ending support for them. However, .NET Framework 4.6.2 and newer versions support newer digital certificates. Please refer to the same from here.

Key points to remember:

  • The control namespaces are the same on both versions, i.e., .NET Framework 4.5.2 & .Net Framework 4.6.2. So, no code change is required while upgrading.
  • ComponentOne's WPF controls that were available with .NET Framework 4.5.2 are also available with .NET Framework 4.6.2. So, you don’t have to worry about control availability in .NET Framework 4.6.2.
  • C1 WPF .NET Framework 4.6.2 assemblies are also shipped as NuGet packages.
