Migrate to OpenIddict 3.0

What's new?

The announcement listing the changes introduced in this milestone can be found here.

IMPORTANT

Migrating to OpenIddict 3.0 requires making changes to your database: existing properties have been reworked and new ones have been added to support the new features.

Update your packages references

For that, update your .csproj file to reference the OpenIddict.AspNetCore 3.x metapackage:

<ItemGroup>
  <PackageReference Include="OpenIddict" Version="2.0.1" /> 
  <PackageReference Include="OpenIddict.AspNetCore" Version="3.1.1" /> 

  <PackageReference Include="OpenIddict.EntityFrameworkCore" Version="2.0.1" /> 
  <PackageReference Include="OpenIddict.EntityFrameworkCore" Version="3.1.1" /> 
</ItemGroup>

Ensure your application doesn't reference legacy/unsupported packages

As part of the AspNet.Security.OpenIdConnect.Server/OpenIddict merge, the ASOS packages and 2 OpenIddict packages have been marked as legacy and are no longer supported. Make sure your application (or intermediate libraries) don't reference any of these packages:

Package name
AspNet.Security.OpenIdConnect.Extensions
AspNet.Security.OpenIdConnect.Primitives
AspNet.Security.OpenIdConnect.Server
Owin.Security.OpenIdConnect.Extensions
Owin.Security.OpenIdConnect.Server
AspNet.Security.OAuth.Introspection
AspNet.Security.OAuth.Validation
Owin.Security.OAuth.Introspection
Owin.Security.OAuth.Validation
OpenIddict.Models
OpenIddict.Mvc

IMPORTANT

If your application references the OpenIdConnectConstants class, update it to use OpenIddictConstants instead.

Update the references to the Entity Framework Core/Entity Framework 6/MongoDB models

If your application references the OpenIddictApplication, OpenIddictAuthorization, OpenIddictScope or OpenIddictToken models, update these reference to use their new names:

Old name	New name (Entity Framework Core)	New name (Entity Framework 6)	New name (MongoDB)
OpenIddictApplication	OpenIddictEntityFrameworkCoreApplication	OpenIddictEntityFrameworkApplication	OpenIddictMongoDbApplication
OpenIddictAuthorization	OpenIddictEntityFrameworkCoreAuthorization	OpenIddictEntityFrameworkAuthorization	OpenIddictMongoDbAuthorization
OpenIddictScope	OpenIddictEntityFrameworkCoreScope	OpenIddictEntityFrameworkScope	OpenIddictMongoDbScope
OpenIddictToken	OpenIddictEntityFrameworkCoreToken	OpenIddictEntityFrameworkToken	OpenIddictMongoDbToken

Enable ASP.NET Core integration in the server and validation options

With the base server and validation stacks being decoupled from ASP.NET Core, you now have to explicitly register the ASP.NET Core host in the server/validation options:

services.AddOpenIddict()
    .AddServer(options =>
    {
        options.UseAspNetCore();
    })
    .AddValidation(options =>
    {
        options.UseAspNetCore();
    });

Enable the authorization, logout and token endpoints pass-through mode

Unless you're using OpenIddict's events model to handle authorization, logout and token requests, you'll need to enable the pass-through mode for these endpoints, so that requests can reach your authorization controller as in the previous versions:

services.AddOpenIddict()
    .AddServer(options =>
    {
        options.UseAspNetCore()
               .EnableAuthorizationEndpointPassthrough()
               .EnableLogoutEndpointPassthrough()
               .EnableTokenEndpointPassthrough();
    });

Enable ASP.NET Core Data Protection support to ensure existing tokens can still be validated

For that, call options.UseDataProtection() in both the server and validation options:

services.AddOpenIddict()
    .AddServer(options =>
    {
        options.UseDataProtection();
    })
    .AddValidation(options =>
    {
        options.UseDataProtection();
    });

Use the new request caching APIs (if applicable)

In 3.0, the OpenIddictServerBuilder.EnableRequestCaching() API - that enabled request caching for both authorization and logout request - was replaced by 2 separate methods. If your application depends on request caching, don't forget to enable it when migrating to 3.0:

services.AddOpenIddict()
    .AddServer(options =>
    {
        options.UseAspNetCore()
               .EnableAuthorizationRequestCaching()
               .EnableLogoutRequestCaching();
    });

Replace JSON.NET by System.Text.Json

If you use JSON.NET to serialize or deserialize OpenIdConnectMessage, OpenIdConnectRequest or OpenIdConnectResponse instances, consider moving to System.Text.Json when migrating to OpenIddict 3.0, as 3.0 no longer includes a built-in JSON.NET JsonConverter for their equivalent in 3.0 (i.e OpenIddictMessage, OpenIddictRequest and OpenIddictResponse).

In most cases, this should be as simple as replacing JsonConvert.SerializeObject()/JsonConvert.DeserializeObject() by their System.Text.Json equivalent: JsonSerializer.Serialize()/JsonSerializer.Deserialize().

Replace calls to the AuthenticationTicket extensions by their new ClaimsPrincipal equivalent:

OpenIddict 3.0 no longer uses the AuthenticationTicket type provided by ASP.NET Core. Instead, everything is now stored in the ClaimsPrincipal instance. If you have calls like ticket.SetScopes() or ticket.SetResources(), use their new equivalents (e.g principal.SetScopes() or principal.SetResources()).

Use the new authentication schemes

In 3.0, the constants used as the ASP.NET Core authentication schemes have changed:

Old constant name	New constant name (ASP.NET Core host)
OpenIddictServerDefaults.AuthenticationScheme	OpenIddictServerAspNetCoreDefaults.AuthenticationScheme
OpenIddictValidationDefaults.AuthenticationScheme	OpenIddictValidationAspNetCoreDefaults.AuthenticationScheme
OAuthValidationDefaults.AuthenticationScheme	OpenIddictValidationAspNetCoreDefaults.AuthenticationScheme

NOTE

In 3.0, the OpenIddict server ASP.NET Core handler supports authenticating userinfo requests. As such, if you use the pass-through mode to handle userinfo requests in your own userinfo MVC action, consider using OpenIddictServerAspNetCoreDefaults.AuthenticationScheme instead of OpenIddictValidationAspNetCoreDefaults.AuthenticationScheme for your userinfo endpoint to avoid validating access tokens twice.

Update your application to work with the new scope format

In OpenIddict 3.0, the format of the scope claim used in JWT tokens has changed from a JSON array to a single space-separated claim to match the JWT access token specification. To ensure your authorization policies still work after migrating, consider using the principal.HasScope() extension to determine whether a scope has been granted:

services.AddAuthorization(options =>
{
    options.AddPolicy("MyPolicy", builder =>
    {
        builder.RequireAuthenticatedUser();
        builder.RequireAssertion(context => context.User.HasScope("api1"));
    });
});

Alternatively, you can use the check the presence of the private OpenIddict oi_scp claims that use the same format as in 2.x (i.e one claim per scope value):

services.AddAuthorization(options =>
{
    options.AddPolicy("MyPolicy", builder =>
    {
        builder.RequireAuthenticatedUser();
        builder.RequireClaim(Claims.Private.Scope, "api1");
    });
});

CAUTION

These 2 options only work with the OpenIddict validation handler as the oi_scp claims are not populated by the JWT bearer handler developped by Microsoft. If you can't migrate to the OpenIddict validation handler, consider splitting the standard scope claim manually to determine whether it contains a specific value.

Add and apply migrations, if necessary

If your application uses Entity Framework Core or Entity Framework 6, add a migration to react to the schema changes listed below and apply it.

Updated properties

Table	Column name	Observations
OpenIddictAuthorizations	Subject	The column is now nullable to support the device authorization flow.
OpenIddictTokens	CreationDate	For broader database support, this column is a now a DateTime instance.
OpenIddictTokens	ExpirationDate	For broader database support, this column is a now a DateTime instance.
OpenIddictTokens	Subject	The column is now nullable to support the device authorization flow.

Added properties

Table	Column name	Type	Nullable
OpenIddictApplications	DisplayNames	string	Yes
OpenIddictApplications	Requirements	string	Yes
OpenIddictAuthorizations	CreationDate	DateTime	Yes
OpenIddictScopes	Descriptions	string	Yes
OpenIddictScopes	DisplayNames	string	Yes
OpenIddictTokens	RedemptionDate	DateTime	Yes

If necessary, enable hybrid flow support in the server options

In 2.0, the hybrid flow was automatically enabled if both the authorization code and implicit flows were enabled. In 3.0, this is no longer true and the hybrid flow MUST be explicitly opted in. If you use the hybrid flow, make sure your application calls the options.AllowHybridFlow() method:

services.AddOpenIddict()
    .AddServer(options =>
    {
        options.AllowHybridFlow();
    });

Update your applications to grant them the appropriate response type permissions

New response type permissions - enforced by default - have been introduced in 3.0.

NOTE

If you have many applications to migrate, you can use this script to infer appropriate response type permissions using the already granted grant types.
