ASP.NET Core : Rest API Documentation Using Swagger & C# Lets see how we can enhance the documentation. A sub project of the OpenApi initiative, Swagger 2.X Annotations uses reflection to generate OpenApi definitions out of code. For information about this in the Swagger Spec, check out the Property Object. The output is a swagger definition file, it can be used then to generate client/server code and API docs. Once you've declared and configured which authorization schemes you support in your API, you can use these annotation to note which authorization scheme is required on a resource or a specific operation. if you dont want to generate the xml document file then we can use Swashbuckle Annotation library to provide more details about API. Note that both parameters have the required property set to true. Now we need to schema filter class SwaggerSchemaExampleFilter.

Wanting to hide a parameter as it is defined and override it with a completely different definition. The discriminator field must be a field at the top model which will be used to determine which sub model is being used. Software architect, Exploring ASP.Net core and containerization technologies. Since this is displayed in the list of operations in Swagger-UI and the location is limited in size, this should be kept short (preferably shorter than 120 characters), The notes allows you to give significantly more details about the operations (e.g. Use Swagger annotations - ServiceComb Java Chassis Developers Guide Drools Decision Table using Simple Example, Understand Swagger-core builds the model definitions based on the references to them throughout the API introspection.
