How can I get Glimpse to work with EF6?

Question

EDIT: stack trace added at bottom.

I have an ASP.NET MVC 5 project that uses a SQL Server database via Entity Framework 6.

I added Glimpse (and Glimpse.MVC5) to the project, and that works fine.

However, when I add Glimpse.EF6, my application throws an exception as soon as it attempts to access the database. The exception is:

System.NotSupportedException

Unable to determine the provider name for provider factory of type 'System.Data.SqlClient.SqlClientFactory'. Make sure that the ADO.NET provider is installed or registered in the application config.

What's going on? FYI, the connectionStrings part of my web.config looks like this:

<connectionStrings>
  <add name="DefaultConnection" connectionString="Data Source=.; Initial Catalog=foo; Integrated Security=True; MultipleActiveResultSets=True;" providerName="System.Data.SqlClient" />
</connectionStrings>

...and my Application_Start method looks like this:

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();
    GlobalConfiguration.Configure(WebApiConfig.Register);
    FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
    RouteConfig.RegisterRoutes(RouteTable.Routes);
    BundleConfig.RegisterBundles(BundleTable.Bundles);

    Database.SetInitializer(new WebApplication.Models.Storage.ApplicationDbInitializer());
}

...and my context class looks like this:

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext()
        : base("DefaultConnection")
    {
    }

    public DbSet<Foo> Foos { get; set; }
}

Thanks in advance for any help...

Could you add a stacktrace? Or even better, create an issue on our issue tracker because this doesn't sound like something you did wrong. Just as a quick check, do you have the same issue when you put the Database.SetInitializer in comments? – Guthrun

@cgijbels:Removing the Database.SetInitializer made no difference. I'll add the stacktrace and create an issue. – Mesmerism

@cgijbels: added as issue 173. Thanks. – Mesmerism

There are currently several issues related to EF6 and Glimpse. Best to report them on the Glipse issues list on github. – Geriatrics

Answer 1

For those of you looking for a workaround:

It looks like it's a bug within EF itself (it was mentioned as 173 above, but the link is correct). You can either wait for EF 6.1.1/6.2 or you can downgrade to EF 6.0.2 and it will start to work again.

In the Package Manager Console, type this:

Install-Package EntityFramework -Version 6.0.2

and you should be good to go.

But only if EF 6.0.2 is an option for you. Good luck.

Rolling back to 6.0.2 won't help those that are using Identity 2.0 – Elgon

Correct - thank you for pointing that out @ScottE. Hopefully the next version of EF comes out quickly and resolves this. – Dialogist

I've rolled back to 6.0.2 and still having an issue.. Did anyone get it sorted? – Taiwan

Answer 2

In case of having problem like Eric Sassaman had, working with Glimpse and seems to hosed your project. Make sure after glimpse remove (from nuget) you've removed all dll's from the bin directory. In my case, Azure build was caching glimpse dll's which made an error like: [NotSupportedException: Unable to determine the provider name for provider factory of type 'System.Data.SqlClient.SqlClientFactory'. Make sure that the ADO.NET provider is installed or registered in the application config.]

Answer 3

Try adding the below to your config file

<configuration>
  <configSections>    
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
  </configSections>
  <entityFramework>
    <defaultConnectionFactory type="System.Data.Entity.Infrastructure.SqlConnectionFactory, EntityFramework" />
    <providers>
      <provider invariantName="System.Data.SqlClient" type="System.Data.Entity.SqlServer.SqlProviderServices, EntityFramework.SqlServer" />
    </providers>
  </entityFramework>
</configuration>

I already had something similar (I did not show the whole of my web.config file - only the connectionStrings element), but interestingly my defaultConnectionFactory was set to the local db provider. Anyway, I changed it to be the same as you suggested, and unfortunately it made no difference - I still get the same error. – Mesmerism

Also, I should add, when I remove Glimpse.EF6, all my database access works fine. It seems to be when I add Glimpse.EF6 that it all goes wrong. – Mesmerism

Wow, installing Glimpse.EF6 seems to have permanently hosed my project, I can't get rid of this error even after uninstalling Glimpse completely. I was forced to restore the entire project from a backup! – Schott

Installing EF from Nuget places the above mentioned config section into the config file. So, while you should check it's there, it's not likely to be the problem if you installed from Nuget. – Mauk
