**********************************Try this one to upload <=500mb in asp.net or also increase the upload size by changing maxRequestLength="512000" ************************
copy in web.config page of your web site

<httpruntime>
executionTimeout="90"

<!-- DYNAMIC DEBUG COMPILATION
Set compilation debug="true" to enable ASPX debugging. Otherwise, setting this value to
false will improve runtime performance of this application.
Set compilation debug="true" to insert debugging symbols (.pdb information)
into the compiled page. Because this creates a larger file that executes
more slowly, you should set this value to true only when debugging and to
false at all other times. For more information, refer to the documentation about
debugging ASP.NET files.
-->
<!--<compilation>
defaultLanguage="c#"
debug="true"
/> -->

<!-- CUSTOM ERROR MESSAGES
Set customErrors mode="On" or "RemoteOnly" to enable custom error messages, "Off" to disable.
Add <error> tags for each of the errors you want to handle.

"On" Always display custom (friendly) messages.
"Off" Always display detailed ASP.NET error information.
"RemoteOnly" Display custom (friendly) messages only to users not running
on the local Web server. This setting is recommended for security purposes, so
that you do not display application detail information to remote clients.
-->
<customerrors>
mode="RemoteOnly"
/>

<!-- AUTHENTICATION
This section sets the authentication policies of the application. Possible modes are "Windows",
"Forms", "Passport" and "None"

"None" No authentication is performed.
"Windows" IIS performs authentication (Basic, Digest, or Integrated Windows) according to
its settings for the application. Anonymous access must be disabled in IIS.
"Forms" You provide a custom form (Web page) for users to enter their credentials, and then
you authenticate them in your application. A user credential token is stored in a cookie.
"Passport" Authentication is performed via a centralized authentication service provided
by Microsoft that offers a single logon and core profile services for member sites.
-->
<!-- <authentication mode="Windows"> -->

<!-- AUTHORIZATION
This section sets the authorization policies of the application. You can allow or deny access
to application resources by user or role. Wildcards: "*" mean everyone, "?" means anonymous
(unauthenticated) users.
-->

<authorization>
<allow users="*"> <!-- Allow all users -->
<!-- <allow users="[comma separated list of users]">
roles="[comma separated list of roles]"/>
<deny users="[comma separated list of users]">
roles="[comma separated list of roles]"/>
-->


<!-- APPLICATION-LEVEL TRACE LOGGING
Application-level tracing enables trace log output for every page within an application.
Set trace enabled="true" to enable application trace logging. If pageOutput="true", the
trace information will be displayed at the bottom of each page. Otherwise, you can view the
application trace log by browsing the "trace.axd" page from your web application
root.
-->
<trace> enabled="false"
requestLimit="10"
pageOutput="false"
traceMode="SortByTime"
localOnly="true"
/>

<!-- SESSION STATE SETTINGS
By default ASP.NET uses cookies to identify which requests belong to a particular session.
If cookies are not available, a session can be tracked by adding a session identifier to the URL.
To disable cookies, set sessionState cookieless="true".
-->
<sessionstate>
mode="InProc"
stateConnectionString="tcpip=127.0.0.1:42424"
sqlConnectionString="data source=127.0.0.1;Trusted_Connection=yes"
cookieless="false"
timeout="20"
/>

<!-- GLOBALIZATION
This section sets the globalization settings of the application.
-->
<globalization>
requestEncoding="utf-8"
responseEncoding="utf-8"
/>

1. In Web.Config file set maxRequestLength equal to max file size in MB
2. Use VarBinary(MAX) as datatype in SQL Server Database
