5.7.0

This release introduces the following changes:

• To increase interoperability and support advanced scenarios, the OpenIddict server now allows using OAuth 2.0 Proof Key for Code Exchange with response_type combinations containing token when response type permissions are not disabled and the appropriate response type permissions are granted to the client application. See #2088 for more information about this change.

• The embedded web server that is part of the OpenIddict client system integration package now natively supports POST callbacks, allowing to use the implicit and hybrid flows - that require response_mode=form_post - in desktop applications.

• response_mode=fragment is now fully supported by the system integration package when using protocol activations or the UWP web authentication broker.

• The OpenIddict client and its ASP.NET Core/OWIN integrations now support setting a specific code_challenge_method/grant_type/response_mode/response_type for each challenge operation:

// Ask OpenIddict to initiate the authentication flow (typically, by starting the system browser).
var result = await _service.ChallengeInteractivelyAsync(new()
{
    // Note: both the grant type and the response type MUST be set when using a specific flow:
    GrantType = GrantTypes.AuthorizationCode,
    ResponseType = ResponseTypes.Code + ' ' + ResponseTypes.IdToken
});

var properties = new AuthenticationProperties(new Dictionary<string, string>
{
    // Note: both the grant type and the response type MUST be set when using a specific flow:
    [OpenIddictClientAspNetCoreConstants.Properties.GrantType] = GrantTypes.AuthorizationCode,
    [OpenIddictClientAspNetCoreConstants.Properties.ResponseType] = ResponseTypes.Code + ' ' + ResponseTypes.IdToken
})
{
    RedirectUri = Url.IsLocalUrl(returnUrl) ? returnUrl : "/"
};

return Challenge(properties, OpenIddictClientAspNetCoreDefaults.AuthenticationScheme);

• The following providers are now supported by the OpenIddict.Client.WebIntegration package:

  • Gitee (thanks @gehongyan! ❤️)
  • Huawei (thanks @gehongyan! ❤️)
  • KOOK (thanks @gehongyan! ❤️)
  • Lark/Feishu (thanks @gehongyan! ❤️)
  • Weibo (thanks @gehongyan! ❤️)

• Behavior change: for boolean values, OpenIddictParameter.ToString() and the string?/string?[]? conversion operators now return true and false instead of True and False.

• The OpenIddict client was updated to detect incorrect uses of its system integration package in non-desktop applications and return proper errors.
