So you have decided to move your ASP.NET MVC2 project  from the Windows Server configured with  ASP.NET 2.0 .NET Framework 3.5
to  ASP.NET 4.0 .NET Framework 4.

Here is how I did it.

My old setup:

Windows Server 2008 R2
IIS 7.5
ASP.NET
Application Pool : .NET Framework v2.0.50727
.NET Framework installed:  3.5 SP1

My new setup:

Windows Server 2008 R2
IIS 7.5
ASP.NET
Application Pool : .NET Framework v4.0.30319
.NET Framework installed:  4.0

The good thing is that the ASP.NET is backward compatible. You shoud publish the website on the new setup and it should work straight away.

In my case I had to remove these from web.config:

<section name="scriptResourceHandler" type="System.Web.Configuration.ScriptingScriptResourceHandlerSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirepermission="false" allowdefinition="MachineToApplication"></section>
<section name="jsonSerialization" type="System.Web.Configuration.ScriptingJsonSerializationSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirepermission="false" allowdefinition="Everywhere"></section><section name="profileService" type="System.Web.Configuration.ScriptingProfileServiceSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirepermission="false" allowdefinition="MachineToApplication"></section><section name="authenticationService" type="System.Web.Configuration.ScriptingAuthenticationServiceSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirepermission="false" allowdefinition="MachineToApplication"></section><section name="roleService" type="System.Web.Configuration.ScriptingRoleServiceSection, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" requirepermission="false" allowdefinition="MachineToApplication"></section>

If it still gives you problems got to IIS Manager and click Error Pages:

Select 500 , right click and select Edit Feature Settings

Here select “Detailed errors”

Now you should get detailed error within your web.config. Also check Event Viewer under the section Administrative Events

You can check your response headers by using Firebug add-on for Firefox or just hit Ctrl+J in Chrome.

Unwanted info:

Server Microsoft-IIS/7.5
X-AspNetMvc-Version 3.0
X-AspNet-Version 4.0.303319
X-Powered-By ASP.NET

1. Removing X-AspNet-Version

In web.config stick this line in

<system.web>
      <httpRuntime enableVersionHeader="false"/>
	...

2. Removing X-AspNetMvc-Version

In Global.asax.cs add this line:

protected void Application_Start()
{
    MvcHandler.DisableMvcResponseHeader = true;
}

3. Removing or changing Server

Add this module class to your project.

using System;
using System.Web;

namespace Project.Infrastructure.Web.Modules.Http
{
    public class CustomHeaderModule : IHttpModule
    {
        public void Init(HttpApplication context)
        {
            context.PreSendRequestHeaders += OnPreSendRequestHeaders;
        }

        public void Dispose() { }

        void OnPreSendRequestHeaders(object sender, EventArgs e)
        {
	     //HttpContext.Current.Response.Headers.Remove("Server");
            // Or you can set something funny
	    HttpContext.Current.Response.Headers.Set("Server", "CERN httpd");
        }
    }
}

And add set it in web config

	<system.webServer>
		<modules>
        <add name="CustomHeaderModule" type="StrongNamespace.HttpModules.CustomHeaderModule" />

4. Removing or changing X-Powered-By

Go to IIS7 Management Console and open HTTP Response Headers

And that should be it!

So........... you are configuring ASP.NET SQL session state and Microsoft's
documentation tells you to execute InstallSqlState.sql found in
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\
but you always get this:

If the job does not exist, an error from msdb.dbo.sp_delete_job is expected.
Msg 14262, Level 16, State 1, Procedure sp_verify_job_identifiers, Line 67
The specified @job_name ('ASPState_Job_DeleteExpiredSessions') does not exist.
If the category already exists, an error from msdb.dbo.sp_add_category is expected.
Msg 14261, Level 16, State 1, Procedure sp_add_category, Line 32
The specified @name ('[Uncategorized (Local)]') already exists.
Well then..... you are doing it wrong. Open command line (Start->Run-> cmd)

1.cd C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\
2) Execute:

aspnet_regsql.exe –ssadd -U <username> -P <passowrd> -S <servername>

For example

aspnet_regsql.exe –ssadd -U webuser -P d4rk!s1de -S mssql.arturito.net You can also do 

aspnet_regsql.exe –ssadd -E -S mssql.arturito.net - if you use Windows authentication

b) aspnet_regsql.exe –ssadd -U <username> -P <passowrd> -S <servername>for exampleb) aspnet_regsql.exe –ssadd -U webuser -P d4rk!s1de -S mssql.arturito.net
