Suspected Bug in ComponentLoader not working with IE and IIS

[edip]

I am experiencing some strange behaviour in Ext.Net V4.2 with Microsoft Visual Studio 2017 and I have attached a document detailing the bug at http://upload.ext.net. It seems that when I use Ext.Net.ComponentLoader with Internet Explorer 11 and IIS, it renders script to my page instead of the actual controls…when I use any other browser it works fine. If I use Internet Explorer 11 with IIS Express, surprisingly that works fine too.

All the responses look the same, but it seems that when it is called with Internet Explorer (using IIS), the request is different. The failing request is using a GET instead of a POST and it does not seem to be using the XmlHttpRequest object…

Working Request (Chrome , Firefox, Opera , IIS Express and Internet Explorer 11 )
