The type or namespace name 'Ports' does not exist in the namespace 'System.IO'

Question

I am working on developing a windows store app on my windows 8.1 system,64 bit (I need to deploy this app on my windows surface pro 3 tablet), technology being used is C#. I need to communicate through the RS-232 port. For this I am using the SerialPort class which falls under the namespace System.IO.Ports. But when I am including this in my C# code, I am getting the error -

"The type or namespace name 'Ports' does not exist in the namespace 'System.IO' (are you missing an assembly reference?)"

I have the windows SDK 8.0 installed. What could be the probable reason for this issue ? Is there any other was to communicate through the RS-232 port .

Any pointer or suggested would be really helpful.

Here is the code -

using System;
using System.IO;
using System.IO.Ports;

namespace App4
{
    public class Class2
    {
        private SerialPort comport = new SerialPort();
    }

    private void SerialPortInit()
        {

            comport.BaudRate = 115200;
            comport.DataBits = 8;
            comport.StopBits = StopBits.One;
            comport.Parity = Parity.None;

        }
}

Google says that Serialport class is supported in dotNetFrameWork 4.5 (which is the one I am using) but still I am getting this error.

Solution 1

Go to Edit->projectsettings->Player->APIcompetibilityLevel = .Net4.x This worked for me.

Solution 2

Problem is the .net configuration.

Use the .NET 2.0 (not subset). Config:

Edit>ProjectSettings>Player>ApiCompatibilityLevel

you probably need to add a reference right click on your project in solution explorer and add reference

Windows Store apps are extremely restricted - it's entirely possible that the Windows Runtime doesn't provide the functionality you need.

See the comment here http://stackoverflow.com/q/25710474/2655508. Hans Passant knows about what he is talking.

I have already tried adding the reference. I have tried adding system.dll but getting this error -"A reference to System.dll could not be added. This component is already automatically referenced by the build system"

[shikha shrivastva]

Do we have any other way to communicate through the RS-232 port other than serialport ?

And I am facing this issue on Windows 8.1 Enterprise and not windows RT
