Increasing IIS Upload Limit

When uploading file to IIS greater than default will lead to
Exception Details: System.Web.HttpException: Maximum request length exceeded.

To solve this problem, we need specify our upload limit the server is allowed to accept say 5MB (1024×5000)
In Web.config > system.web add
<httpRuntime maxRequestLength="5120000" executionTimeout="3600" />

In Web.config > system.webServer
        <requestLimits maxAllowedContentLength="5120000" />

Note: maxRequestLength and maxAllowedContentLength must match
