However, instead of setting a flag, you can configure the generator to ignore obsolete actions altogether: A similar approach can also be used to omit obsolete properties from Schemas in the Swagger output. Is it ok to store this in implementation notes ? https://learn.microsoft.com/ef/core/saving/index. HttpClient

In Swashbuckle, you can define schemes by invoking the AddSecurityDefinition method, providing a name and an instance of OpenApiSecurityScheme. For example, if you have an action that returns a Product type, then the generated schema will be referenced as follows: However, if it encounters multiple types with the same name but different namespaces (e.g. lastName: Mello, This versioning mechanism is simple and depends on the server routing the request to the appropriate endpoint. Were continuing our series on building HTTP APIs with .NET 5. If I use a None List-Class its works.

For example, the following filter lists an additional "401" response for all actions that are decorated with the AuthorizeAttribute: NOTE: Filter pipelines are DI-aware. Swashbuckle retrieves an ApiDescription, part of ASP.NET Core, for every action and uses it to generate a corresponding OpenApiOperation.

As a result, the generated request/response schemas will reference a collection of "possible" schemas instead of just the base class schema: As inheritance and polymorphism relationships can often become quite complex, not just in your own models but also within the .NET class library, Swashbuckle is selective about which hierarchies it does and doesn't expose in the generated Swagger. For example, if you'd like to include an example for a specific type in your API.
