I'm experimenting with I'm trying to configure I'm dealing with I tried several approaches but none seem to work. After trying multiple solutions online, I still can't figure this out. After updating my project to .NET 7 in Visual Studio 2022, I'm working with an scenario where the namespace 'System.Text.Json' want to be resolved. Initially, my project was using .NET 6, and everything was working fine. I updated the target framework in my `.csproj` file to `<TargetFramework>net7.0</TargetFramework>`, but now I'm getting the behavior: ``` The type or namespace name 'Text' does not exist in the namespace 'System' (are you missing an assembly reference?) ``` I tried cleaning and rebuilding the solution, but that didn't resolve the scenario. I also checked my NuGet packages and ensured that 'System.Text.Json' is installed and is the latest version (7.0.0) compatible with .NET 7. Here’s a snippet of my `Program.cs` where I'm trying to use `JsonSerializer`: ```csharp using System; using System.IO; using System.Text.Json; class Program { static void Main(string[] args) { var jsonData = JsonSerializer.Serialize(new { Name = "John", Age = 30 }); Console.WriteLine(jsonData); } } ``` I also verified that my project settings are correct, and everything seems to point to .NET 7. I even cleared the NuGet cache in case there were lingering issues. Is there something specific I should look for regarding this namespace scenario after upgrading? Any insights would be appreciated! How would you solve this? I'm working with C# in a Docker container on Windows 10. How would you solve this? Any ideas what could be causing this? I'm working in a Windows 10 environment. How would you solve this?
