Does not exist in the Namespace - Keeps returning - what am I missing?

I'm editing a C# script in Visual Studio for an SSIS package.

 

I have two lines that give me errors:

var tokenResult = JsonSerializer.Deserialize<JsonElement>(result);

var token = new System.IdentityModel.Tokens.Jwt.JwtSecurityToken(accessToken);

 

The first one complains that "JsonSerializer" does not exist in the context and "JsonElement" couldn't be found.

The second has "System.IdentityModel.Tokens.Jwt" does not exist in the namespace.

 

 

If I open the package manager and run the following line, the errors go away and the script compiles cleanly.

PM> Install-Package System.IdentityModel.tokens.Jwt

If I save everything and run the package it fails at the script. Opening the script again reveals the errors are BACK.

Its almost like I'm not committing the changes somehow. Any help would be greatly appreciated. Thanks!

    @William Zorn, Welcome to Microsoft Q&A,

    The first one complains that "JsonSerializer" does not exist in the context and "JsonElement" couldn't be found.

    For your first error, please install nuget-package System.Text.Json and don't forget to add the using statement on the left-top of your code using System.Text.Json;.

    The second has "System.IdentityModel.Tokens.Jwt" does not exist in the namespace.

    For your second error, I think you have already done for it (install nuget-package System.IdentityModel.Tokens.Jwt).

    The following is my result, which does not have the compiling error:

    Hope my solution could help you.

    Best Regards,

    Jack
