The .NET API wrapper is useful for .NET developers who wish to seamlessly integrate the <a href="https://docs.what3words.com/api/v3/" target="_blank" rel="noopener">what3words API</a> into their applications, without the hassle of having to manage the low level API calls themselves.
A full example of a .NET application is available in our <a href="https://github.com/what3words/w3w-dotnet-wrapper" target="_blank" rel="noopener">GitHub</a> repository.
The what3words API is a fast, simple interface which allows you to convert 3 word addresses such as ///index.home.raft to latitude and longitude coordinates such as (-0.203586, 51.521251) and vice versa. It features a powerful AutoSuggest function, which can validate and correct user input and limit it to certain geographic areas (this powers the search box on our map site). It allows you to request a section of the what3words grid (which can be requested as GeoJSON for easy display on online maps), and to request the list of all languages supported by what3words. For advanced users, AutoSuggest can be used to post-process voice output.
All coordinates are latitude,longitude pairs in standard WGS-84 (as commonly used worldwide in GPS systems). All latitudes must be in the range of -90 to 90 (inclusive).
