If I try to upload a file bigger than the allowed file size, the upload component calls the OnProgress function with 100% completion. The upload controller is not called as there is an error in the POST operation. The error I've got is this:
HTTP Error 404.13 - Not Found
The request filtering module is configured to deny a request that exceeds the request content length.
However, the blazor application does not get any error notification whatsoever, so it gets into an invalid state. I know that I can increment the file size limit in the application configuration files, but the point is that ther can be any error in the upload process (f.e. network error, server busy, etc) and the application would not get any feedback about it.
