How to register the 'entityFramework' section of the application config file in EF6

Trying to configure the web.config for my ASP.Net application with EF6 (.Net Framework version 4.6). I am receiving the following error. Thank you for your assistance.
ERROR:
System.InvalidOperationException: 'The Entity Framework provider type 'System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer' registered in the application config file for the ADO.NET provider with invariant name 'System.Data.SqlClient' could not be loaded. Make sure that the assembly-qualified name is used and that the assembly is available to the running application.

AjaxControlToolkit AjaxFileUpload can't upload IIS Reserved File Types

I am writing/ have written a file upload portal for my company that requires the ability to upload a ton of different file types of various sizes and quantities. I used the AJaxControlToolkit AjaxFileUpload control.
The upload works well except when we upload what seems like IIS reserved file types. We can upload images, entire non-zipped folders, office docs etc.
When I try to upload the reserved file type the Firefox developer tools returns a server error, 'File Extension Not Allowed' error. This happens with .exe files and the one we need .stl files(in our case these are for 3d printing).
We have played with config files, Handler Mappings, HTTP response headers, MIME type configurations, and request filtering on the IIS manager at the app level, site level and server level and none seem to work.
The last bit of info is that zipping the file seems to get it through but we'd like to avoid asking the customer to do that.
IIS 8.5,
C# .Net,
Windows Server 2012 R2
I can post code if you need it but I am pretty sure it is a server configuration we need to change
Thanks for your help.

Below is my Config with the Fix included. this was an issue with white listed file types by the control and not the server. Thank you

You need to add the additionalUploadFileExtensions attribute to ajaxControlToolkit section in Web.config:
<ajaxControlToolkit additionalUploadFileExtensions="exe,stl" />
Please refer to this article: https://github.com/DevExpress/AjaxControlToolkit/wiki/AjaxFileUpload-setup

For an example of where to ajaxcontroltoolkit entry in the web.config file, please refer to Sample web.config Ajax configuration
Sample below:
<configuration>
<configSections>
<section name="ajaxControlToolkit" type="AjaxControlToolkit.AjaxControlToolkitConfigSection, AjaxControlToolkit" requirePermission="false"/>
</configSections>
<ajaxControlToolkit
useStaticResources="true"
renderStyleLinks="false"

Trying to add "Free Text Box" to a web.config file

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>
<connectionStrings>
<add name="ConnectionString" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\PageContent.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/>

Does anyone have any idea what I am doing wrong?

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" />
</handlers>
</system.webServer>

I've ran into a weird issue when ever I deploy to my winhost account and try to login using membership provider it works fine locally but once it's on the intarnets it breaks.

any ideas or help is appreciated!

Look at the bottom of your error message. It is not talking about app.config; rather machine.config.
<root drive>:\<windows>\Microsoft.NET\Framework\<version>\config\machine.config
This is what it looks like in mine:
<roleManager>
<providers>
<add name="AspNetSqlRoleProvider" connectionStringName="LocalSqlServer" applicationName="/" type="System.Web.Security.SqlRoleProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
<add name="AspNetWindowsTokenRoleProvider" applicationName="/" type="System.Web.Security.WindowsTokenRoleProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />
</providers>
</roleManager>

I got this error deploying an ASP.NET MVC 4 site to Winhost.
The answer is to add this to your project's web.config file per this link.
<connectionStrings>
<remove name="LocalSqlServer" />
<add name="LocalSqlServer" connectionString="Data Source=DBServerName;Integrated Security=false;Initial Catalog=DBName;User ID=DBLogin;Password=DBPassword" providerName="System.Data.SqlClient" />
</connectionStrings>
You have to add both the remove name and add name.
