Can you add a License? I'd like to use this in a project. Thanks

The FlowUpload-Attribute allows to specify accepted file-extensions:

[HttpPost]
[FlowUpload("png", "jpg")]
[ActionName("Upload")]
public ActionResult Upload(FlowFile file)
{
return Json(new { derp = file.flowFilename });
}

If a file is with the name "example.jpg" is uploaded everything works fine. As soon as the file-extension is for example uppercase ("example.JPG") the file isn't accepted for upload and the response from the Upload-Method isn't delivered to the caller.

I tracked down the problem down to FlowChunk.cs. Around line 66 you'll find the following statement:

 if (rules.AcceptedExtensions.Count > 0 && rules.AcceptedExtensions.SingleOrDefault(x => x == FileName.Split('.').Last()) == null)
                errorMessages.Add(rules.AcceptedExtensionsMessage ?? "type");

This code should accept files where the extension has a different case.
