Nuget re-targeting after upgrading from .Net Framework 4.5 to 4.6.1

Upgrading from .NET Framework 4.5 to 4.6.1 and Retargeting NuGet Packages

Are you facing the challenge of upgrading your .NET solution from version 4.5 to 4.6.1? Do you have concerns about retargeting your NuGet packages during this upgrade process? If so, you're in the right place! 🚀

The Dilemma

Let's begin by addressing the first question. Do you need to re-target your NuGet packages when performing an "in-place" upgrade from .NET Framework 4.5 to 4.6.1? The short answer is yes, and here's why:

When you upgrade the target framework version of your projects, the NuGet packages they reference may not be compatible with the new framework version. This means you need to ensure that your NuGet packages are targeting the correct framework version for your updated project.

The Solution

Now that we understand the importance of retargeting our NuGet packages, how can we go about doing it? The good news is that it's a relatively straightforward process. Follow these steps to update your packages.config file for each project:

1. Open the packages.config file for a project.

2. Locate the targetFramework attribute and change the value from net45 to net461.

3. Save the file and repeat these steps for each project in your solution.

By making this simple modification, you are effectively informing NuGet to use the correct version of the package that is compatible with .NET Framework 4.6.1.

The Catch

Although the steps mentioned above seem simple enough, sometimes they may not work perfectly on the first try. You may encounter a few errors during the process. 😬

If you followed the steps and faced issues, don't worry! You might need to uninstall and then reinstall the problematic NuGet packages. To do this, use the Update-Package command in the NuGet Package Manager Console.

Here's an example of how to use the command:

Update-Package ExamplePackage -ProjectName YourProjectName -Version 1.2.3

Remember to replace ExamplePackage with the actual name of the NuGet package you're working with and YourProjectName with the name of your project.

Wrapping Up

Upgrading your .NET Framework version can be challenging, but with the right approach and a bit of patience, you can successfully retarget your NuGet packages to match the new framework version. 🎉
