NOTE: if you're editing the project files, when working with a target with Wi-Fi capabilities, make sure to add HAS_WIFI into the DefineConstants, like this:

<DefineConstants>$(DefineConstants);HAS_WIFI;</DefineConstants>

Note: This sample is part of a large collection of nanoFramework feature samples. 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 any shared dependencies.

1. Start Microsoft Visual Studio 2022 or Visual Studio 2019 (Visual Studio 2017 should be OK too) and select File > Open > Project/Solution.
2. Starting in the folder where you unzipped the samples/cloned the repository, go to the subfolder for this specific sample. Double-click the Visual Studio Solution (.sln) file.
3. Press Ctrl+Shift+B, or select Build > Build Solution.

The next steps depend on whether you just want to deploy the sample or you want to both deploy and run it.

• Select Build > Deploy Solution.

• To debug the sample and then run it, press F5 or select Debug > Start Debugging.
