Optimise multi-part streaming file upload performance, offering 10x improvement in performance, and reduced memory allocation (10%-40%).

By default dotnet model form model binding loads the entire stream into memory using IFormFile - this is non-ideal for large files where processing of the stream should occur during streaming rather then buffering entire file(s) to memory/disk.

This package allows upload streams to be asynchronously processed via a delegate while maintaining generic model binding functionality with ModelState validation.

Usage

[HttpPost("upload")]
public async Task<IActionResult> Upload() {
    // returns a generic typed model, alternatively non-generic overload if no model binding is required
    MyModel model = await this.StreamFiles<MyModel>(async formFile => {
        // implement processing of stream as required via an IFormFile interface
        using (var stream = formfile.OpenReadStream())
            await ...
    });
    // ModelState is still validated from model
    if(!ModelState.IsValid)
        ...
}
