Any idea how I can upload a large video in the media manager through the built-in visual studio IIS Express runtime? I have added data in my appsettings.json according to the document, but no success 😦 "Runtime": { "MaxQueryStringLength": 9000, "MaxRequestLength": 200000000 },

you probably need to add this into the web.config file (create one if it doesn't exist.

<system.webServer>
        <security>
            <requestFiltering>
                <requestLimits maxAllowedContentLength="524288000"/>
            </requestFiltering>
        </security>
</system.webServer>

you're a genius
