Importing System.Management.Automation with Unity

For reasons, I need to use PowerShell to get information about the computer's IP. Therefore, I tried using System.Management.Automation along with NugetForUnity, but VS keeps saying that The type or namespace name 'Automation' does not exist in the namespace 'System.Management' (are you missing an assembly reference?) I know for a fact that I have installed the package, but I have not gotten anywhere with this project for the past 4 hours. Does anybody have any advice? Here is my code:
using System.Management.Automation;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class getLocation : MonoBehaviour
{
// Start is called before the first frame update
void Start()
{
//https://www.codeproject.com/Questions/1206308/Powershell-commands-from-Csharp
//Modified by #alex#6555
using (var ps = PowerShell.Create())
{
ps.AddCommand("curl");
ps.AddArgument("ipinfo.io");
}
}
// Update is called once per frame
void Update()
{
}
}
If anybody knows what to do, some pointers would be greatly appreciated.

The type or namespace couldn't be find , how to fix it?

So im doing a unity car game and one of my script for the physics is not working and i dont know why.
there is my code :
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
[RequireComponent(typeof(InputManager))]
public class CarController : MonoBehaviour
{
public InputManager im;
public List<wheelCollider> steeringWheel;
public List<wheelCollider> piloteWheel;
and i got the following errors : "error CS0246: The type or namespace name 'wheelCollider' could not be found (are you missing a using directive or an assembly reference?)"
Do you know how to fix it ?

You have a typo, 'wheelCollider' should be 'WheelCollider' with an uppercase 'W'.

Microservices in SF: C# can't find type

I'm implementing a number of micrososervices with C# and Service Fabric. All has gone well until this error which seems to be a C# error:
Severity Code Description Project File Line Suppression State
Error CS0246 The type or namespace name 'IProductCatalogService' could not be found (are you missing a using directive or an assembly reference?) ECommerce.API C:\dev\ECommerce\ECommerce.API\Controllers\ProductsController.cs 14 Active
IProductCatalogService is the project ECommerce.ProductCatalog.Model which I have set a project dependency to and I am referencing with a using statement:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using ECommerce.API.Model;
using Microsoft.AspNetCore.Mvc;
namespace ECommerce.API.Controllers
{
[Route("api/[controller]")]
[ApiController]
public class ProductsController : ControllerBase
{
private readonly IProductCatalogService _catalogService;
Here it is ECommerce.ProductCatalog.Model:
using System.Collections.Generic;
using System.Threading.Tasks;
using Microsoft.ServiceFabric.Services.Remoting;
namespace ECommerce.ProductCatalog.Model
{
public interface IProductCatalogService : IService
{
Task<IEnumerable<Product>> GetAllProducts();
Task AddProduct(Product product);
}
}
What am I missing?

From the screenshots above, it looks like you're missing out on referencing to the right project. You want to use using Ecommerce.Productcatalog.Model after you add the reference of Ecommerce.Productcatalog.Model in UI Project.
And from your comments it looks like you have done that and yet you're not able to add that reference. In that case, can you share the screenshot of what it says when you try adding that using statement and also share the project/folder structure if possible, so we can take a look it further.

TcpChannel could not be found

I'm following a lab tutorial on .NET remoting and for that I need to create TcpChannel object. For that I have added using System.Runtime.Remoting namespace but it still gives me an error The type or namespace name 'TcpChannel' could not be found (are you missing a using directive or an assembly reference?)
I'm using Visual Studio 2015 Community Edition. I can't figure out what is causing this problem. I even googled it. Here's my code
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Runtime.Remoting;
namespace RemotingServer
{
class Program
{
static void Main(string[] args)
{
TcpChannel channel = new TcpChannel(8001);
}
}
}

The TcpChannel class is located in System.Runtime.Remoting.Channels.Tcp, so you have to get using that. Also check if you reference System.Runtime.Remoting.dll in your project.

Namespaces and classes missing from referenced DLL

I'm trying to add a reference to a project ("Geometry") that lives in another solution ("Bar Solution") into another solution ("Foo Solution"). Any project in Bar Solution (the home of the Geometry's source code) can import Geometry and use its features with no problem; however, when I add the DLL to Foo Solution, it imports fine, but the Object Browser shows it containing no namespaces or classes.
Has anyone experienced this problem or otherwise know of a solution? I can't find any information on SO or more generally, le Goog.
Object Browser of Foo Solution:
Bar's Solution Explorer:
Some code from Foo which is trying to use "Geometry":
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using Geometry; // Error: "The type or namespace name 'Geometry' could not be found
// (are you missing a using directive or an assembly reference?)"
namespace Lever
{
public partial class LeverGUI : Form
{
public LeverGUI()
{
InitializeComponent();
}
}
}
