Visual Studio 2022 - Getting 'The type or namespace name could not be found' scenarios when using a specific NuGet package
I'm building a feature where I've been working on this all day and After trying multiple solutions online, I still can't figure this out... I'm upgrading from an older version and I'm working with a frustrating scenario in Visual Studio 2022 involving a package I recently added... After installing the 'Newtonsoft.Json' NuGet package, I am getting the compiler behavior: `The type or namespace name 'JsonConvert' could not be found (are you missing a using directive or an assembly reference?)`. I've confirmed that the package is installed and visible in the 'Manage NuGet Packages' dialog. Here's what I've tried: 1. Restarting Visual Studio to refresh the project references. 2. Cleaning and rebuilding the solution. 3. Ensuring that I'm targeting the correct .NET Framework version (4.7.2) that is compatible with the package. 4. I manually checked the `packages.config` file to ensure that the 'Newtonsoft.Json' entry is present. 5. I also tried using `#r "Newtonsoft.Json.dll"` in my script, but that did not resolve the scenario either. Here's a snippet of the code where the behavior occurs: ```csharp using Newtonsoft.Json; public class JsonExample { public void ConvertToJson(object obj) { string json = JsonConvert.SerializeObject(obj); // Other logic... } } ``` I've also verified that my project file (`.csproj`) correctly references the package: ```xml <PackageReference Include="Newtonsoft.Json" Version="13.0.1" /> ``` Interestingly, when I create a new console application and add the same package, it works without issues. I'm not sure what else to look for. Any suggestions on how to resolve this behavior? For reference, this is a production REST API. What's the best practice here? This is part of a larger microservice I'm building. This is part of a larger application I'm building. Thanks in advance! Could someone point me to the right documentation?
