Does the `IHttpRequestBodyFeature` interface exist?

[Taritsyn]

After updating ASP.NET Core to version 3.0 Preview 8 in my project, that using the IHttpBufferingFeature interface, I received the following compilation error:

Error	CS0619	'IHttpBufferingFeature' is obsolete: 'See IHttpRequestBodyFeature or IHttpResponseBodyFeature DisableBuffering'

It is clear that I should refuse to use the obsolete interface, but it is completely unclear where the IHttpRequestBodyFeature interface is defined and whether it exists at all?

Thanks for contacting us, @Taritsyn.
@Tratcher what's the alternative here?

Were you using DisableRequestBuffering? How/why?

Honestly we hadn't seen any reported usages of that API, it's not hooked up to anything by default.

Hello, Chris!

Were you using DisableRequestBuffering? How/why?

I use it for implementing ASP.NET Core middleware, which produce a markup minification and HTTP compression (see source code of the stream wrapper).

Honestly we hadn't seen any reported usages of that API, it's not hooked up to anything by default.

This API is mentioned here.

That's only using response buffering. It only called request buffering as passthrough because they were combine on the old interface. You can remove that call.

ОК. Thank you!
