While being able to offload to statsd/graphite/raygun/... is great, a "state of the nation" dashboard would be really handy.

This could show requests/sec, wait times, "slow" requests, auth failures, live access map, recent exceptions, known issues (e.g. can't connect to redisX/mssqlY)

Being able to bulk insert/copy would be cool.

Adding support in so I could just take a list and

Db.BulkCopy(listOfObjects);

would be pretty sweet.

SqlServer has the bulkCopy object, postgres has the copy command, sqlite has import (although no idea how well that works) , and mysql...well...who cares (i don't know what they have)

Having a single interface for bulk copying objects into different databases I think would be a nice feature for ormlite. (not sure how feasible)

Currently redis client is not async - this is wasting valuable resources on the server side. As far as I understand async support is currently only there for service clients and not redis

Building upon swagger feature, (but possibly re-engineering)

Support to include:
- complex (nested) DTO's and array
- markdown documentation (for detailed description)
- role/access based display (so only authorised endpoints are displayed)
- rebranding support
- ability to install nuget package without /docs folder (so as to get annotations, but not html in a model lib)

Support to automatically update a db schema based on changes such as: adding/renaming and possibly removing a property or class.

Much like you have created a RedisSentinel object ... I have a need for a RedisCluster object that supports the new feature which is coming in v3.0. Thanks.

support localization in messages for validations or any other messages sent to the client

The c# SDK is seriously lagging in documentation. By that I mean IntelliSense documentation: it would be awsome with some "in line" documentation for methods and properties in the SDK

At the moment, the *OAuth2 Providers for ServiceStack* library does not support .net core, as explained by mythz in this StackOverflow answer:

> ServiceStack's OAuth2 depends on DotNetOpenAuth which unfortunately doesn't support .NET Core so there's currently no support for OAuth2 - https://stackoverflow.com/a/42344183/969613

Google Authentication is a feature requirement on my current project, so this one thing is preventing us from moving to .net core, support for this would be great.

Swagger now support oAuth login page to create a access_token to apply to a oAuth protected API: http://developers-blog.helloreverb.com/enabling-oauth-with-swagger/

Please could you add a similar capability to ServiceSatck.SwaggerFeature that enables SS developers to add a similar capability to their own APIS that are protected by oAuth.

"OpenID Connect (OIDC) is an authentication layer on top of OAuth 2.0, an authorization framework." The benefit to developers and consumers is a more simplified way to add a new Auth provider which would provide some standard user info.

I would like to have an OpenId and OAuth integration with Thinktecture.IdentityServer just like google and Facebook. I would like to implement my own SSO instead of relying on social networking OpenId

Provide async overloads for caching API so async operations can construct the cache.

More info:

Many serious architecture work on Restful+JSON and consumers are more and more asking for some WADL to industrialize their exchanges.
This may be a main criteria to select a ServiceStack.
So i suggest the WADL implementation directly on ServiceStack.

Create a starter template showing how to use ServiceStack + SharePoint together.
