[Breaking change]: Minimal API renames in RC2

[halter73]

Description

In RC2, the following APIs were renamed or merged.

• The Microsoft.AspNetCore.Builder.DelegateEndpointConventionBuilder class was renamed to Microsoft.AspNetCore.Builder.RouteHandlerBuilder.
• The Microsoft.AspNetCore.Http.OpenApiDelegateEndpointConventionBuilderExtensions class was renamed to Microsoft.AspNetCore.Http.OpenApiRouteHandlerBuilderExtensions.
• The Microsoft.AspNetCore.Builder.DelegateEndpointRouteBuilderExtensions class was removed and all of its methods were merged into the existing Microsoft.AspNetCore.Builder.EndpointRouteBuilderExtensions class.

These changes were made in dotnet/aspnetcore#36578.

Version

.NET 6 RC2

Previous behavior

There is no behavioral change. These are just renames.

New behavior

There is no behavioral change. These are just renames.

Type of breaking change

• Binary incompatible: Existing binaries may encounter a breaking change in behavior, such as failure to load/execute or different run-time behavior.
• Source incompatible: Source code may encounter a breaking change in behavior when targeting the new runtime/component/SDK, such as compile errors or different run-time behavior.

Reason for change

This change was made to improve the consistency of type names replacing DelegateEndpoint with RouteHandler now that there is a new RouteHandlerOptions class.

Recommended action

It is recommended you recompile any projects built with an earlier SDK. For most projects, this should be all that is necessary.

If any of these type names were referenced directly by name, the source should be updated to reflect the new names.

Affected APIs

• Microsoft.AspNetCore.Builder.DelegateEndpointConventionBuilder
• Microsoft.AspNetCore.Http.OpenApiDelegateEndpointConventionBuilderExtensions
• Microsoft.AspNetCore.Builder.DelegateEndpointRouteBuilderExtensions
