The OpenAPI.NET SDK contains a useful object model for OpenAPI documents in .NET along with common serializers to extract raw OpenAPI JSON and YAML documents from the model.

See more information on the OpenAPI specification and its history here: Open API Initiative

Project Objectives

  • Provide a single shared object model in .NET for OpenAPI descriptions.
  • Include the most primitive Reader for ingesting OpenAPI JSON and YAML documents in both V2 and V3 formats.
  • Provide OpenAPI description writers for both V2 and V3 specification formats.
  • Enable developers to create Readers that translate different data formats into OpenAPI descriptions.

Installation

  • Install core Nuget package Microsoft.OpenApi
  • Install readers Nuget package Microsoft.OpenApi.Readers

Processors

The OpenAPI.NET project holds the base object model for representing OpenAPI documents as .NET objects. Some developers have found the need to write processors that convert other data formats into this OpenAPI.NET object model. We'd like to curate that list of processors in this section of the readme.

The base JSON and YAML processors are built into this project. Below is the list of the other supported processor projects.

  • C# Comment / Annotation Processor : Converts standard .NET annotations ( /// comments ) emitted from your build (MSBuild.exe) into OpenAPI.NET document object.

  • OData CSDL Processor : Converts the XML representation of the Entity Data Model (EDM) describing an OData Service into OpenAPI.NET document object.

Example Usage

Creating an OpenAPI Document

var document = new OpenApiDocument
{
    Info = new OpenApiInfo
    {
        Version = "1.0.0",
        Title = "Swagger Petstore (Simple)",
    },
    Servers = new List<OpenApiServer>
    {
        new OpenApiServer { Url = "http://petstore.swagger.io/api" }
    },
    Paths = new OpenApiPaths
    {
        ["/pets"] = new OpenApiPathItem
        {
            Operations = new Dictionary<OperationType, OpenApiOperation>
            {
                [OperationType.Get] = new OpenApiOperation
                {
                    Description = "Returns all pets from the system that the user has access to",
                    Responses = new OpenApiResponses
                    {
                        ["200"] = new OpenApiResponse
                        {
                            Description = "OK"
                        }
                    }
                }
            }
        }
    }
};

Reading and writing a OpenAPI description

var httpClient = new HttpClient
{
    BaseAddress = new Uri("https://raw.githubusercontent.com/OAI/OpenAPI-Specification/")
};

var stream = await httpClient.GetStreamAsync("master/examples/v3.0/petstore.yaml");

// Read V3 as YAML
var openApiDocument = new OpenApiStreamReader().Read(stream, out var diagnostic);

// Write V2 as JSON
var outputString = openApiDocument.Serialize(OpenApiSpecVersion.OpenApi2_0, OpenApiFormat.Json);
