HTTP Request Exception Xamarin Forms

Question

I am sending a large video file (average file size of 50mb) to my server using HttpClient and PostAsync. I am getting an exception (see below for full exception details). I found a article that the maximimum file size that can be handled is 1mb or less is this true? If so, how can I increase the maximum file size?

@G.hakim I am send the whole byte array I tried Krunal's suggestion now there is no exception but the video is not created — user10200885
Well I cannot remote right now but I can give you a suggestion link check this where the guy is sharing the large file as partitions or data chunks — FreakyAli

If your are saving the uploaded video in server using api, May be your max request length smaller than your uploded video size. If you want to upload high size video, Then increase the max request length in your webconfig file. Here is the sample code for increasing max request lenght in web api project.

  <httpRuntime targetFramework="4.5.2" maxRequestLength="15200" />
