Increasing Upload Limit for IIS

By default, the IIS 7 upload limit is 30 million bytes (~3.5 MB)

In order to increase it, in Web Config modify the maxAllowedContentLength attribute:

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