__NOTOC__
We provide support for the C# language in all major operating systems. We also provide instructions on how to get your project started in a number of common development environments. Select your operating system and preferred development environment below, and follow the instructions to get your project running with Phidgets.


__TOC__
If you do not know which development environment you want to use, or your development environment of choice is not listed, we recommend starting with Mono as the simplest path to getting your code running. Visual Studio is the most popular way to build C# projects, but it also has a steep learning curve.


==Introduction==
Once you have set up your development environment to run with Phidgets, we recommend you follow our guide on [[Phidget Programming Basics]]. The guide will showcase the fundamentals of programming with Phidgets, with examples in C#.

===Libraries===
===Libraries===
*[http://www.phidgets.com/downloads/libraries/phidget21-x86_2.1.8.20110615.zip .NET Framework Files]
===Description===
C# programs on Windows depend on the following files, which the installers above put onto your system:
* <code>phidget21.dll</code> contains the actual Phidgets library, which is used at run-time.  If you used our installer, it's already correctly placed in <code>C:\Windows\System32</code>.  It can be manually installed - check our [[Manual Installation instructions]].
You will also need one of the following two files:
* <code>Phidget21.NET.dll</code> is the Phidgets library for .NET framework 2.0 or higher. It is installed automatically with our installer. However, it can also be [[manually installed]].
* <code>Phidget21.NET1.1.dll</code> is the Phidgets library for .NET framework 1.1. It is installed automatically with our installer. However, it can also be [[manually installed]].
You can also optionally install the following files:
* <code>Phidget21.NET.XML</code> provides the IntelliSense in-line documentation for the .NET library in Visual Studio. This documentation is also visible in the Object Browser.
* <code>Policy.2.1.Phidget21.NET.dll</code> is the policy assembly for Phidget21.NET.dll. It is installed in the Global Assembly Cache(GAC). it directs any programs compiled against version 2.1.0 or higher of Phidget21.NET.dll to use the most recent installed version.
Running the examples and writing your own code can be fairly compiler-specific, so we include instructions for each compiler below.
===Visual Studio===
====Visual Studio 2005/2008/2010====
Please start by downloading the C# Examples.  These examples were written in Visual Studio 2005 and 2008, but Visual Studio 2010 will easily upgrade them.
*[http://www.phidgets.com/downloads/examples/CSharp_2.1.8.20110615.zip Microsoft Visual C# Examples]
Microsoft makes free versions of Visual Studio available known as Express Editions.  The Express editions are suitable for most applications, but are limited in features for more complex applications. Please see [http://www.microsoft.com/visualstudio Microsoft Visual Studio] for more information.
=====Use Our Examples=====
If you are opening the Phidget examples in Visual Studio 2010, you will need to go through the Visual Studio Conversion Wizard to convert the 2005 or 2008 project.
<br/><br/>[[File:VS2005 Conversion Wizard.PNG]]<br/><br/>
To run the examples, you first download them [[#Visual Studio|from above]] and unpack them into a folder.  To load all projects in Visual Studio, go to File | Open | Project, and open <code>AllExamples.sln</code> or <code>AllExamples_vs2008.sln</code> for Visual Studio 2005 and 2008, respectively.
This will load all of the examples available for C#, and then you can set your main project to be the one that matches your device.  If you aren't sure what the software example for your device is called, check the software object listed in the [[Device List | Getting Started guide for your device]].
The only thing left to do is to run the examples! Click on Debug -> Start Debugging. Please note that the projects, by default try to find the <code>Phidget21.NET.dll</code> in the <code>$(SystemDrive)\Program Files\Phidgets</code>. If you have it installed in another location, please change the path accordingly. If you are receiving an error message regarding that the namespace Phidgets cannot be found, please re-add the reference to Phidget21.NET.dll(or Phidget21.NET1.1.dll. Please see the [[#Write Your Own Code | next section]] for details.
<br/><br/>
[[File:CSharp VS2005 Run.PNG ‎]]
<br/><br/>
Once you have the C# examples running, we have a [[#Follow The Examples|teaching section]] below to help you follow them.
=====Write Your Own Code=====
When you are building a project from scratch, or adding Phidget function calls to an existing project, you'll need to configure your compiler / development environment to properly link the Phidget C# libraries. To begin:
* Generate a new Visual C# Windows Applications project with a descriptive name such as PhidgetTest.
<br/>[[File:CSharp VS2005 New Project.PNG ]]
<br/>
* Add a reference to the .NET Phidgets lilbrary.
<br/>[[File:CSharp VS2005 Add Reference.PNG ]]<br/>
* Under the .NET tab, select <code>Phidget21.NET.dll</code>. Please note that if you are programming under .NET framework 1.1, please use <code>Phidget21.NET1.1.dll</code> instead.
<br/>If you used our installer, these files are installed in <code>C:\Program Files\Phidgets</code>, by default. If it does not appear in this list, then you can browse to the Phidget Framework installation directory and add the file.
<br/>[[File:CSharp VS2005 Add Reference 2.PNG ]]<br/><br/>
Then, in your code, you will need to include the Phidget library:
<div style="background-color: #f3f3f3; border-color: #1c9edb; border-width:1px; border-style: dashed;">
<font size="3">
<source lang=cpp>
  using Phidgets;
  using Phidgets.Events;
  </source>
</font>
</div>
The project now has access to the Phidget21 function calls and you are ready to begin coding.
The same [[#Follow The Examples|teaching section]] which describes the examples also has further resources for programming your Phidget.
====Visual Studio 2003====
Start by downloading the C# Examples.
*[http://www.phidgets.com/downloads/examples/CSharp_2.1.8.20110615.zip Microsoft Visual C# Examples]
As the examples were written in newer versions of Visual Studio, Visual Studio 2003 is not able to open the examples. Fortunately, you can import the simple examples to a project. It will be difficult to import the full examples as you will need to recreate the GUI components. In the next section, it will be assumed that the simple examples are used.
=====Use Our Examples=====
<br/>
Download the examples [[#Visual Studio 2003|from above]] and unpack them into a folder. Here, you can find example programs for all the devices. If you are not sure what the software example for your device is called, check the software object listed in the [[Device List | Getting Started guide for your device]]. You will need this example source code to be copied into your C# project later on.
Next, a new project will need to be created.
* Generate a new Visual C# console application project with a descriptive name such as PhidgetTest.
<br/>[[File:CSharp_VS2003 New Project.PNG]]<br/><br/>
* Add a reference to the .NET Phidgets lilbrary.
<br/>[[File:CSharp_VS2003 Add Reference 1.PNG]]<br/><br/>
* Under the .NET tab, select <code>Phidget21.NET1.1.dll</code>.
<br/>[[File:CSharp_VS2003 Add Reference 2.PNG]]<br/><br/>
To import the simple example program into your project, please:
* Open up Class1.cs .
* Traverse to the example and locate the <code>Program.cs</code> file.
<br/>[[File:CSharp VS2003 Source Code.PNG]]<br/><br/>
* Copy and paste the contents from that file into Class1.cs.
* Comment out <code>using System.Collections.Generic;</code> as it is not supported in .NET 1.1.
<br/>[[File:CSharp VS2003 Source Code 2.PNG]]<br/><br/>
Then, in your code, you will need to include the Phidget library:
<div style="background-color: #f3f3f3; border-color: #1c9edb; border-width:1px; border-style: dashed;">
<font size="3">
<source lang=cpp>
  using Phidgets;
  using Phidgets.Events;
</source>
</font>
</div>
The project now has access to the Phidget21 function calls and you are ready to begin coding.
Now, you can run the example. Click on Debug | Start.

The dotnet command-line interface is the quickest way to start programming in C# on MacOS and Linux.

Installing dotnet CLI

First, make sure you have the Phidgets Drivers for MacOS installed (see this page for installation instructions).

Next, visit Microsoft's .NET page and download .NET after confirming compatibility with your version of MacOS.

Click on the .pkg file once it's finished downloading, and follow the steps to install the .NET SDK.

Setting up a New Project

Open Finder and go to Utilities -> Terminal. Create a new C# project using the following command:

dotnet new console -o helloworld

This will create a new C# console application in a folder named helloworld in your current directory. Next, type cd helloworld to enter the folder, and type:

dotnet run

If everything installed properly, the application will build and you'll see 'Hello, World!' printed in the terminal. You can open Program.cs using the text editor to see the code.

Getting Phidgets Sample Code

Next we'll use this base project to run some Phidgets sample code. Go to the product page for your Phidget and go to the Code Samples tab. Select C# from the language drop-down and use the check boxes to modify the example if you'd like.

Click the copy button in the corner of the code sample and paste it into the Program.cs for your HelloWorld program, overwriting the existing code.

Compile and Run

Once you've pasted the sample code into the .cs file and saved, you need to add the Phidgets .NET package to your project using this terminal command:

dotnet add package Phidget22.NET

Then you can re-build the project using

dotnet run

Success! The project is now using Phidgets.
