Install failed. Rolling back...
Could not install package 'Microsoft.Owin.Security 2.0.2'. You are trying to install this package into a project that targets '.NETFramework,Version=v4.0', but the package does not contain any assembly references that are compatible with that framework. For more information, contact the package author.
on also in my web.config line <httpRuntime targetFramework="4.5"/> says
the targetFramework attribute is not allowed.
and my web.config is

Please am fairly new to programming in asp.net and now am following the steps in a textbook to design an e-commerce web application.
I am using UrlRewritingNet dll from http://www.urlrewriting.net/ to create search engine friendly urls on the application. I unzipped the urlrewritingnet zip and copied its dll file to my application's bin folder. I also copied its urlrewritingnet.xsd file to my project folder. The textbook am working from uses the dll from urlrewriter.net with different configurations which I tried in my project but it didn't work. The textbook also uses visual web developer 2005. Am programming in visual studio 2012 (C#). For now am trying to rewrite the url of my catalogs page so as to test if the configuration in my web.config file is correct. I'm doing the configuration in my web.config, not in IIS. I do not want any IIS configurations because am imagining a scenario where I don't have access to the server.
I keep getting an internal server error that displays like this:
HTTP Error 500.22 - Internal Server Error
An ASP.NET setting has been detected that does not apply in Integrated managed pipeline mode.
this is the url which I want to rewrite: http://localhost:1036/Catalog.aspx?DepartmentID=1
This is my config file:

Pls I need you lovely guys to help me out. Am really stuck. I've searched all round the internet for over 4 days in search of solution but to no avail. Thanks in anticipation.
You can checkout the following link:url-rewriting-in-Asp-Net
So, I added a FTB by using a Formview that connects the database to the webpage.
When I tried to run the page and use the FTB, I was greeted with the following message:
"FreeTextBox has not been correctly installed. To install FreeTextBox either:
(1) add a reference to FtbWebResource.axd in web.config:
<system.web>
<httpHandlers>
<add verb="GET"
path="FtbWebResource.axd"
type="FreeTextBoxControls.AssemblyResourceHandler, FreeTextBox" />
</httpHandlers>
</system.web>
(2) Save the FreeTextBox image and javascript files to a location on your website and set up FreeTextBox as follows
<FTB:FreeTextBox id="FreeTextBox1" SupportFolder="ftbfileslocation" JavaScriptLocation="ExternalFile" ButtonImagesLocation="ExternalFile" ToolbarImagesLocation="ExternalFile" ButtonImagesLocation="ExternalFile" runat="server" />"
I have already gone to the FTB download site and acquired the DLL. I created a bin folder in Visual Studio 2013 Exp and added the DLL to the file.
My web config currently looks like this:
<?xml version="1.0"?>
<configuration>

If you are using IIS 7 and above you might want to register it in the handlers section of the System.webServer section.
<system.webServer>
<validation validateIntegratedModeConfiguration="false"/>
<handlers>
<add name="FreeTextBox" path="FtbWebResource.axd" verb="GET" type="FreeTextBoxControls.AssemblyResourceHandler, FreeTextBox" preCondition="integratedMode" />

I was checking that this is a problem in the connection string with Integrated Security but in my case I don't have that property. What could be the error?
This error is from Entity - it has little to do with Silverlight. It happens when one of two things happen:
Entity tries to log in to the database you've pointed it to, and is denied permission/can't find the server/can't find the instance/has some other connection error
Entity successfully logs in, but can't find the data model it recognizes
The second should be very simple to check since you have a working local. If the data model on your local is the same as the data model in your 'production' environment, then that part is taken care of. If you have tables that are different, you could have some issues. This is doubly true if they are missing columns that you've coded in to Entity's data model. Entity will tolerate extra columns and extra tables in many cases, though this changes a lot based on the situation, so YMMV. However, if Entity expects something to be there and it's not, it'll crash with a quickness every time.
My larger suspicion would be that rather awesome connection string you have there. You should be able to check the InnerException on what you're getting to see the specific gripe that the database server is raising. If it isn't, I would rip that out into a console application and attempt to connect with a plain jane SqlConnection doing a simple Select count(Id) from dbo.SmallTable. This will allow you to isolate the connection problems and deal with them in a nice, restricted environment. After you've sorted through the connection issues, you can paste your connection string - now hopefully less confusing - back in and move on.
when I debug my project, there are 5 messages (example: Could not find schema information for the element 'entityFramework'. Web.config) and the application doesn't work (error: Unable to find the requested .Net Framework Data Provider. It may not be installed.).
Web.config:

And the object 'System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection' doesn't exist.
What should I do? Thanks.
I had a similar error and I've got rid of it. My web config however referred to a version of 4.4 (not 4.3.1 as you have) which as far as I know doesn't exist. This arose after I grabbed a starter package for the WebAPI with MVC4 from somewhere or other.
V4.3.1 and now V5.0 pre-release do exist as of Aug 2012
I got the nuget package for 4.3.1 using the solution level "library package manager". This is an important step as I could choose which projects to apply it to.
During this process, my web config was changed (to ref 4.3.1) and the problem went away.
What bugs me is that reference to "System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection" cos I cant find where it exists but at least VS isn't complaining any more.
I've been trying to setup a webpage with MVC3 Razor, SQLCE 4 and Code First, the last two downloaded from Nuget, so it is EF Code First CTP5.
I've had a lot of trouble, but I manage to move forward by following this answer
However now I am getting this Security Exception
Description: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application's trust level in the configuration file.
I thought it should work without full trust so I don't know what is wrong now.
I am using GoDaddy shared hosting with .Net 4 and IIS7
What could be the issue?
EDIT:
I haven't modified the web.config, except for setting custom errors = false to be able to see the exceptions, otherwise I have the webconfig that was generated by using Nuget to get and configure SQLCE and Code first

It seems to be a bug with CTP5 that will be fixed in final release.
http://connect.microsoft.com/VisualStudio/feedback/details/641462/ef-code-first-issue-with-medium-trust
Hmmm as I said in the first comment on the question, it is an error with Code First CTP5, which uses full trust instead of medium trust. Source
