问题
I am running an ASP.NET 5 project in an Azure Web App.
When calling on an API endpoint with a file (form-data) of about 1.5mb or larger, the following exception is thrown.
Here is where the exception is thrown from.
Does anyone know how this can be fixed? Is there a possible workaround?

I filed this on aspnet/KestrelHttpServer. It has been accepted as a bug and has recently been included into the 1.0.0-rc2 milestone. See issue here.

Well, remember ASP.NEt 5 still being in RC, so maybe in your VS the current version is even more inmature, this error looks a little bit weird but looks like a web server error. The web server part of asp.net 5 is kestrell and that match with your stack trace Microsoft.AspNet.Server.Kestrel
I'm going to recommend you
- Update your Kestrell server assemblies to last RC Nov 18 your VS could be waiting for that update.
- If the error persist post an issue in Kestrell ASP.Net 5 GitHub this could be a bug related to others already opened talking about content lenght https://github.com/aspnet/KestrelHttpServer/labels/bug
