What's new in OpenIddict RC2?

The full list of changes can be found here. It includes bug fixes (including a bug fix in the refresh token handling) and new features like application permissions, that allow limiting the OpenID Connect features (endpoints and flows) an application is able to use.

Migrate to OpenIddict RC2

Migrating to OpenIddict RC2 (1.0.0-rc2-* and 2.0.0-rc2-*) requires making changes in your database: existing properties have been reworked (e.g to work around a MySQL limitation) and new ones have been added to support the new features. This procedure is quite easy and only requires a few minutes.

Note: this guide assumes your application uses the OpenIddict Entity Framework Core 2.x stores. If you use a custom store, changes will have to be made manually. A list of added/updated/renamed columns is available at the end of this guide.

Ensure migrations are correctly enabled for your project

Before migrating to OpenIddict RC2, make sure migrations are already enabled for your application. If you have a Migrations folder in your application root folder and an __EFMigrationsHistory table in your database, you're good to go.

If you don't have these Entity Framework Core artifacts, migrations are likely not enabled. To fix that, add the following entries in your .csproj:

<ItemGroup>
  <PackageReference Include="Microsoft.EntityFrameworkCore.Design"
                    Version="2.0.0" PrivateAssets="All" />
</ItemGroup>

<ItemGroup>
  <DotNetCliToolReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet"
                          Version="2.0.0" />
</ItemGroup>

Then, open a new command line and add an initial migration using dotnet ef migrations add InitialMigration (but don't apply it!).

Update your packages references

For that, simply update your .csproj file to point to the newest OpenIddict packages:

ASP.NET Core 1.x

<ItemGroup>
  <PackageReference Include="OpenIddict" Version="1.0.0-rc2-*" />
  <PackageReference Include="OpenIddict.EntityFrameworkCore" Version="1.0.0-rc2-*" />
  <PackageReference Include="OpenIddict.Mvc" Version="1.0.0-rc2-*" />
</ItemGroup>

ASP.NET Core 2.x

<ItemGroup>
  <PackageReference Include="OpenIddict" Version="2.0.0-rc2-*" />
  <PackageReference Include="OpenIddict.EntityFrameworkCore" Version="2.0.0-rc2-*" />
  <PackageReference Include="OpenIddict.Mvc" Version="2.0.0-rc2-*" />
</ItemGroup>

Add a new migration

First, open a new command line and run dotnet ef migrations add MigrateToOpenIddictRc2.
If you created an initial migration at step 1, remove it from the Migrations folder.
Apply the MigrateToOpenIddictRc2 migration using dotnet ef database update MigrateToOpenIddictRc2.

Run the migration script to convert columns to the new format

For that, add the following snippet to your Startup class:

private async Task UpdateOpenIddictTablesAsync(IServiceProvider services)
{
    using (var scope = services.GetRequiredService<IServiceScopeFactory>().CreateScope())
    {
        // Change ApplicationDbContext to match your context name if you've changed it.
        var context = scope.ServiceProvider.GetRequiredService<ApplicationDbContext>();
        await context.Database.EnsureCreatedAsync();

        // If you use a different entity type or a custom key,
        // change this line (e.g OpenIddictApplication<long>).
        foreach (var application in context.Set<OpenIddictApplication>())
        {
            // Convert the space-separated PostLogoutRedirectUris property to JSON.
            if (!string.IsNullOrEmpty(application.PostLogoutRedirectUris) &&
                 application.PostLogoutRedirectUris[0] != '[')
            {
                var addresses = application.PostLogoutRedirectUris.Split(
                    new[] { " " }, StringSplitOptions.RemoveEmptyEntries);

                application.PostLogoutRedirectUris =
                    new JArray(addresses).ToString(Formatting.None);
            }

            // Convert the space-separated RedirectUris property to JSON.
            if (!string.IsNullOrEmpty(application.RedirectUris) &&
                 application.RedirectUris[0] != '[')
            {
                var addresses = application.RedirectUris.Split(
                    new[] { " " }, StringSplitOptions.RemoveEmptyEntries);

                application.RedirectUris = new JArray(addresses).ToString(Formatting.None);
            }
        }

        // If you use a different entity type or a custom key,
        // change this line (e.g OpenIddictAuthorization<long>).
        foreach (var authorization in context.Set<OpenIddictAuthorization>())
        {
            // Convert the space-separated Scopes property to JSON.
            if (!string.IsNullOrEmpty(authorization.Scopes) && authorization.Scopes[0] != '[')
            {
                var scopes = authorization.Scopes.Split(
                    new[] { " " }, StringSplitOptions.RemoveEmptyEntries);

                authorization.Scopes = new JArray(scopes).ToString(Formatting.None);
            }
        }

        await context.SaveChangesAsync();
    }
}

Then, at the end of the public void Configure(IApplicationBuilder app) method, add the following line:

public void Configure(IApplicationBuilder app)
{
    app.UseDeveloperExceptionPage();

    app.UseStaticFiles();

    app.UseStatusCodePagesWithReExecute("/error");

    app.UseAuthentication();

    app.UseMvcWithDefaultRoute();

    // Run the migration script synchronously.
    UpdateOpenIddictTablesAsync(app.ApplicationServices).GetAwaiter().GetResult();
}

Run your application. Once it's correctly started, stop it and remove the migration script.

If your authorization server uses introspection, make sure resources are set in the authentication ticket

Setting an explicit list of resources is now required to allow client applications to introspect a token. For that, call ticket.SetResources() with the list of the client identifiers allowed to validate the token. E.g:

var ticket = new AuthenticationTicket(
    new ClaimsPrincipal(identity),
    new AuthenticationProperties(),
    OpenIdConnectServerDefaults.AuthenticationScheme);

ticket.SetResources("tracking_api", "marketing_api");

Optionally, update your code to grant applications the minimum required permissions

Starting with RC2, OpenIddict includes an optional feature codenamed "app permissions" that allows controlling and limiting the OAuth2/OpenID Connect features a client application is able to use.

To learn more about this feature, read the Application permissions documentation.
