Windows Internet of Things (IoT) Samples

This repo contains samples that demonstrate usage patterns for Microsoft's Windows 10 IoT. These code samples were created with templates available in Visual Studio and are designed, but not limited to, run on devices using Windows IoT Enterprise.

Note: If you are unfamiliar with Git and GitHub, you can download the entire collection as a ZIP file, but be sure to unzip everything to access shared dependencies. For more info on working with the ZIP file, the samples collection, and GitHub, see Get the UWP samples from GitHub. For more samples, see the Samples portal on the Windows Dev Center.

Windows 10 IoT development

These samples require Visual Studio and the Windows Software Development Kit (SDK) for Windows 10.

Using the samples

The easiest way to use these samples without using Git is to download the zip file containing the current version (using the following link or by clicking the "Download ZIP" button on the repo page). You can then unzip the entire archive and use the samples in Visual Studio.

Download the samples ZIP

Notes:

• Before you unzip the archive, right-click it, select Properties, and then select Unblock.
• Be sure to unzip the entire archive, and not just individual samples. The samples all depend on the SharedContent folder in the archive.
• In Visual Studio, the platform target defaults to ARM, so be sure to change that to x64 or x86 if you want to test on a non-ARM device.

The samples use Linked files in Visual Studio to reduce duplication of common files, including sample template files and image assets. These common files are stored in the SharedContent folder at the root of the repository and are referred to in the project files using links.

Reminder: If you unzip individual samples, they will not build due to references to other portions of the ZIP file that were not unzipped. You must unzip the entire archive if you intend to build the samples.

For more info about the programming models, platforms, languages, and APIs demonstrated in these samples, please refer to the guidance, tutorials, and reference topics provided in the Windows 10 documentation available in the Windows Developer Center. These samples are provided as-is in order to indicate or demonstrate the functionality of the programming models and feature APIs for Windows.

Contributing

These samples are direct from the feature teams and we welcome your input on issues and suggestions for new samples. If you would like to see new coverage or have feedback, please consider contributing. You can edit the existing content, add new content, or simply create new issues. We’ll take a look at your suggestions and will work together to incorporate them into the docs.

This project welcomes contributions and suggestions. Most contributions require you to agree to a Contributor License Agreement (CLA) declaring that you have the right to, and actually do, grant us the rights to use your contribution. For details, visit https://cla.opensource.microsoft.com.

Note:

• When contributing, make sure you are contributing from the develop branch and not the master branch. Your contribution will not be accepted if your PR is coming from the master branch.

When you submit a pull request, a CLA bot will automatically determine whether you need to provide a CLA and decorate the PR appropriately (e.g., status check, comment). Simply follow the instructions provided by the bot. You will only need to do this once across all repos using our CLA.

This project has adopted the Microsoft Open Source Code of Conduct. For more information see the Code of Conduct FAQ or contact opencode@microsoft.com with any additional questions or comments.
