# GeoJSON.NET
GeoJSON.Net is a .NET library for the [RFC 7946 The GeoJSON Format](https://tools.ietf.org/html/rfc7946) and it uses and provides [Newtonsoft Json.NET](http://json.codeplex.com) converters for serialization and deserialization of GeoJSON data.

## Installation & Usage

[GeoJSON.Net NuGet package](https://www.nuget.org/packages/GeoJSON.Net/):
`Install-Package GeoJSON.Net`

### Serialization

```csharp
Position position = new Position(51.899523, -2.124156);
Point point = new Point(position);

string json = JsonConvert.SerializeObject(point);
```

### Deserialization

```csharp
string json = "{\"coordinates\":[-2.124156,51.899523],\"type\":\"Point\"}";

Point point = JsonConvert.DeserializeObject<Point>(json);
```

See the [Tests](https://github.com/GeoJSON-Net/GeoJSON.Net/tree/master/src/GeoJSON.Net.Tests) for more examples.

## Special considerations for ASP.Net Core 3.1+

System.Text.Json is the default (recommended) serializer. GeoJSON.Net **does not play well with System.Text.Json** and only supports Newtonsoft.Json

[GeoJSON.Text](https://github.com/GeoJSON-Net/GeoJSON.Text) is a fork of this repository and have been developed to support System.Text.Json.

If you still need to use Newtonsoft.Json in ASP.Net Core 3.1+, you must overwrite the default serializer.

- add the "Microsoft.AspNetCore.Mvc.NewtonsoftJson" NuGet Package
- add "services.AddControllers().AddNewtonsoftJson();" to your service configuration.
