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.

Cannot find the namespace for generic type "List"

I have a strange error and don't know how to solve that. I have a Form which gets opened by another (Main)Form. When I write
List<String> valStoreAsString = new List<String>();
I get "The value or namespace List could not get found". My using directives are the following:
using System;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Data.SqlClient;
using System.Collections;
using System.Runtime.InteropServices;
In the other Forms it works fine. What happened here?

Add following using directive to the list of usings.
using System.Collections.Generic;
Tip
If you are using Visual Studio and if you don't know the namespace then type name of type (Case sensetive) in editor and then press ctrl+ . and select add using option and VS will add related using for you.
or you can right click on name of Type and select Resolve option and select using .... sub option.

The type or namespace name 'Uri' could not be found: (System.Uri namespace is included)

I am learning ASP.NET by following one online tutorial (building web application). Problem is when I reuse tutor code I stuck on this error:
Error 1 The type or namespace name 'Uri' could not be found (are you missing a using directive or an assembly reference?)
I tried to include several namespaces (like System.Uri) and none of them worked. Does someone knows where's the problem and what do I need to do to solve the problem?
Here is code:
using System.Collections.Generic;
using System.Net;
using System.Linq;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
using System.Data.Entity;
using System.Web;
using System.Web.Http;
using System.Net.Http;
using System.Data.Entity.Infrastructure;
using System.Uri;
public HttpResponseMessage Post(Friend friend)
{
if (ModelState.IsValid)
{
db.Friends.Add(friend);
db.SaveChanges();
HttpResponseMessage response = Request.CreateResponse(HttpStatusCode.Created, friend);
response.Headers.Location = new Uri(Url.Link("DefaultApi", new { id = friend.FriendId }));
return response;
}
else
{
return Request.CreateErrorResponse(HttpStatusCode.BadRequest, ModelState);
}
}

You can't have using System.Uri;, since Uri is a class (and static import isn't allowed until Visual Studio 2015, which I suppose you are not using now, even in VS 2015, it would fail since Uri is not a static class)
Include:
using System;
and remove
using System.Uri;

from microsoft doc
http://msdn.microsoft.com/en-us/library/system.uri%28v=vs.110%29.aspx
the refence to include is System.dll This should be there by default. Check if you did not delete it by mistake.

You're missing an assembly. You must have had it handy as a reference when compiling your app, but it's not there where you're testing.
So it has nothing to do with your code, but your build and deploy process — i.e., shell scripts, NAnt, VS.
A typical YouTube client will have the following DLL's in the same directory as the EXE (or DLL).
Google.GData.Client.dll
Google.GData.Extensions.dll
Google.GData.YouTube.dll
If not, then they need to be installed in the GAC, or otherwise locatable using .NET's assembly binding configuration. Probably you want the first option, though.
