ServiceStack - Posting multiple files with one POST request - post

Question

I'm struggling with this issue for several hours, and I can't find any solution.
Does someone used ServiceStack to upload multiple files with one POST request?
I was trying to use PostFile:
FileInfo fi = new FileInfo("ExampleData\\XmlAPI.xml");
var client = new XmlServiceClient("http://localhost:1337");
client.PostFile<DefaultResponse>("/test", fi, "application/xml");
But here I am able to add only one file to the request.
My second shot was to use LocalHttpWebRequestFilter but inside there is only a extension method which also allows to post only one file.

Multiple File Upload APIs have been added to all .NET Service Clients in v4.0.54 that allow you to easily upload multiple streams within a single HTTP request. It supports populating Request DTO with any combination of QueryString and
POST'ed FormData in addition to multiple file upload data streams:
using (var stream1 = uploadFile1.OpenRead())
using (var stream2 = uploadFile2.OpenRead())
{
var client = new JsonServiceClient(baseUrl);
var response = client.PostFilesWithRequest<MultipleFileUploadResponse>(
"/multi-fileuploads?CustomerId=123",
new MultipleFileUpload { CustomerName = "Foo,Bar" },
new[] {
new UploadFile("upload1.png", stream1),
new UploadFile("upload2.png", stream2),
});
}
Or using only a Typed Request DTO. The JsonHttpClient also includes async equivalents for each of the new
PostFilesWithRequest APIs:
using (var stream1 = uploadFile1.OpenRead())
using (var stream2 = uploadFile2.OpenRead())
{
var client = new JsonHttpClient(baseUrl);
var response = await client.PostFilesWithRequestAsync<MultipleFileUploadResponse>(
new MultipleFileUpload { CustomerId = 123, CustomerName = "Foo,Bar" },
new[] {
new UploadFile("upload1.png", stream1),
new UploadFile("upload2.png", stream2),
});
}
