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.).

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.

You could try to set the value for |DataDirectory| during runtime:
AppDomain.CurrentDomain.SetData("DataDirectory", #"C:\Program Files (x86)\Company\AppFolder\")
Or replace |DataDirectory| with an absolute path in your configuration file.
I am trying to use my model and create a database from it. When i try to generate a database based on the model i get the following error:

I know the issue is with the MySql.Data.MySqlClientbased on the error message, but i can't seem to figure out what it wants me to do. I have added MySql.Data, MySql.Data.Entity.EF6 and EntityFramework to the project.
Anyone knows how to fix this issue?
I was facing the same problem before this. I manage to solve it by creating a whole new project.
Go to Manage NuGet Packages, install EntityFramework, MySql.ConnectorNET.Data and MySql.ConnectorNET.Entity.
Use the connection string as shown here <add name="SomeDatabase" providerName="MySql.Data.MySqlClient" connectionString="server=localhost;port=3306;database=example;uid=hello;password=user"/>
Add [DbConfigurationType(typeof(MySql.Data.Entity.MySqlEFConfiguration))] in DbContext class.
I have updated my project from EF5 to EF6, using NuGet, but am getting an error now as soon as my application tried to query the database.
error 0152: No Entity Framework provider found for the ADO.NET
provider with invariant name 'System.Data.SqlClient'. Make sure the
provider is registered in the 'entityFramework' section of the

I think the issue is with my data project's App.Config, which resembles this:

My web.config only has a connection string applied:
<connectionStrings>
<!--SERVER -->
<!--LOCAL-->

I think I need to add or remove something from one of these, but not sure which. It worked fine under EF5. Project compiles and builds, and I can edit my EDMX file (I can update model from database).
What am I doing wrong?
I have solution with 3 projects:
1) - library
2) - test (windows forms application)
3) - windows service
Library uses Entity Framework. When i link it to test application it works. My App.config (for test application) looks like this:

<provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
</providers>
</entityFramework>
</configuration>
I've referenced to library in service also. I installed it and run, but when it try to use Entity Framework some exception is thrown, there is log:
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. See http://go.microsoft.com/fwlink/?LinkId=260882 for more information.
App.config in service project is copy-pasted from test application. EntityFramework.dll exists in debug folder.
I'm using EntityFramework with Windows Azure platform. It works so well in LOCAL mode, but when I'm trying to run my Silverlight application on Web. I get an error:
The underlying provider failed on Open.

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.
