It seems like you’re having trouble updating your packages in Visual Studio due to a missing package: ‘System.Diagnostics.DiagnosticSource’. Here are the steps you can follow to resolve this issue: Restore the missing package : Before you can update your packages you need to restore any missing packages. You can do this by running the following command in the Package Manager Console: PM> Install-Package System.Diagnostics.DiagnosticSource Update the packages : Once the missing package is restored you can attempt to update your packages again using the Update-Package -Reinstall command that you’ve been using. If the problem persists it might be due to a problem with the NuGet package source. You can check and update your package sources by following these steps: Go to Tools > Options > NuGet Package Manager > Package Sources in Visual Studio. Check if the package source is enabled and up-to-date. The official NuGet source is https://api.nuget.org/v3/index.json . Remember to restart Visual Studio after modifying the package sources. I hope this helps! Let me know if you have any other questions. ??
