Could not load file or assembly "Newtonsoft.Json, Version=4.5.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed"

"Could not load file or assembly 'Newtonsoft.Json', Version=4.5.0.0, Culture=neutral, PublicKeyToken=30ad4fe6b2a6aeed' 😱"

Have you ever encountered the dreaded error message above? If so, you're not alone! This error is a common issue that many developers come across, especially during the CI build process. But fear not, in this blog post, I'm going to walk you through the problem, provide easy solutions, and give you an engaging call-to-action to spark reader engagement. Let's dive in! 🚀

The Problem 😕

The error message indicates that the application failed to load the assembly 'Newtonsoft.Json' with the specified version, culture, and public key token. This happens when the assembly's manifest definition doesn't match the assembly reference, resulting in a System.IO.FileLoadException. In simpler terms, the application is unable to find the correct version of the 'Newtonsoft.Json' assembly that it needs to run. Bummer, right? 😞

Common Solutions 💡

1. Check the version and compatibility: Verify that the 'Newtonsoft.Json' assembly version specified in the error message matches the one referenced in your application. Sometimes, there might be a minor version mismatch, causing the error. Consider updating or downgrading the assembly version to match your application's requirements.

2. Inspect the dependency tree: The 'Newtonsoft.Json' assembly may have other dependencies that your application also requires. Ensure that all these dependencies are present and correctly referenced in your project. One missing or mismatched dependency could trigger the error.

3. Binding Redirect in configuration: As mentioned in the context, one solution attempted was a binding redirect. A binding redirect redirects the assembly reference from a specified version to another. Although this is a common solution, it might not always work due to various factors. Nevertheless, it's worth a try, especially if you're dealing with multiple versions of the same assembly across your project.

4. Clean and Rebuild: Sometimes, the error can be caused by a corrupt or conflicting cache. Try cleaning the build output and rebuilding the solution to see if it resolves the issue. This simple step can occasionally work like magic! ✨
