Answer 1

I had the same issue. I checked the version of System.Data.SqlServerCe in C:\Windows\assembly. It was 3.5.1.0. So I installed version 4.0.0 from below link (x86) and works fine.

Add these lines to your web.config file:

<system.data>
    <DbProviderFactories>
               <add name="MySQL Data Provider" invariant="MySql.Data.MySqlClient" description=".Net Framework Data Provider for MySQL" type="MySql.Data.MySqlClient.MySqlClientFactory,MySql.Data,  Version=6.6.4.0, Culture=neutral, PublicKeyToken=C5687FC88969C44D"/>
    </DbProviderFactories>
</system.data>

Change your provider from MySQL to SQL Server or whatever database provider you are connecting to.

Answer 3

I was able to solve a problem similar to this in Visual Studio 2010 by using NuGet.

Go to Tools > Library Package Manager > Manage NuGet Packages For Solution...

In the dialog, search for "EntityFramework.SqlServerCompact". You'll find a package with the description "Allows SQL Server Compact 4.0 to be used with Entity Framework." Install this package.

An element similar to the following will be inserted in your web.config:

<entityFramework>
  <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlCeConnectionFactory, EntityFramework">
    <parameters>
      <parameter value="System.Data.SqlServerCe.4.0" />
    </parameters>
  </defaultConnectionFactory>
</entityFramework>

Answer 4

This error is mainly due to processor architecture incompatibility with Framework installed ei x86 vs x64 The solution: Go to solution explorer>project properties>Compile tab>Advanced Compile Options There you have to change Target CPU from X64 to X86 Save new setting and recompile your solution. I tried it and it worked very fine. Hope this will help you out. Malek

Answer 5

I had the same when following MvcMusicStore Tutorial in Part 4 and replaced the given connection String with this:

add name="MusicStoreEntities" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;database=MvcMusicStore;User ID=sa;password=" providerName="System.Data.SqlClient"/>

It worked for me.

Answer 6

This happened to me because I created a new project which was trying to use System.Web.Providers DefaultMembershipProvider for membership. My DB and application was set up to use System.Web.Security.SqlMembershipProvider instead. I had to update the provider and connection string (since this provider seems to have some weird connection string requirements) to get it working.
