[C# Client] Binary string parameters not supported?

Hi.

The OpenAPI 3 specification specifies that files can be sent in a request by declaring that a parameters is of the type string with the format binary: https://swagger.io/docs/specification/describing-request-body/file-upload/

The proposed way to send a single file is as shown below:

    requestBody:
      content:
        image/png:
          schema:
            type: string
            format: binary

When generating a C# client, I would expect to give some sort of Stream (e.g. FileStream) or a byte[], but the client wants me to supply a normal string. From what I can understand, this is not what the OpenAPI spec means with “binary string”. Are strings of format binary not currently supported? Is support planned?

@RSuter Ok, thank you for your quick response. Would you mind listing roughly what needs to be done to support it? I am interested in taking a look at it, but no promises.

Can I assume that this is also unimplemented for C# controllers? I see that string/binary multipart specs in openapi3 result in simple string JSON body objects in the controller code and not in any stream/IFile code?
