Hi

In my application user can define multiple filters for specific type. I would like to somehow combine these queries in single one.

SqlExpression<Notice> query1 = Db.From<Notice>(s=>s.param1 == 2);
// ...queries are more complicated but result type is same
SqlExpression<Notice> query2 = Db.From<Notice>(s=>s.param1 == 3 && s.param2 == 3);

SqlExpression<Notice> unionAll = query1.UnionAll(query2);
var result = Db.Select(unionAll);

With .NET Core not initially having support for Windows Authentication using the System.Directory assemblies, I would like to request the addition of a new LDAP Authentication Provider based on the Novell.Directory.Ldap.NETStandard (https://github.com/dsbenghe/Novell.Directory.Ldap.NETStandard) project. This will allow developers to update to the latest ServiceStack while still providing a way to authenticate and authorize against a legacy/non-Azure Active Directory.

We have message-level encryption and the corresponding .Net client library to use it. But I'd love to be able to call encrypted services from JavaScript. Ideally add to ss-utils.js, or because the encryption can get bulky, into a new ss-encrypt-utils.js.

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

Take a project like http://www.mattjcowan.com/funcoding/2013/05/11/restful-api-and-ui-for-typed-views-and-typed-lists/
and lift it to the next level.
Purpose: Point ActiveScaffold with AutoCrud to your database, and you get a half sensible CRUD web interface to maintain it. In other words, an instant backoffice.
This is orthogonal to any other API usage of ServiceStack.

Inspired by the Rails equivalent "https://github.com/activescaffold/active_scaffold&quot; that is very nicely designed, with both configuration and override possibilities.

Using servicestack client in mobile development with Xamarin gives so much benefits and caching dramatically improves performance and user experience.
It would be nice to have same caching support for all clients (.NET, JAVA, ..)

I've just stumbled upon Facebook's GraphQL and it's pretty slick.
The ability to query a ServiceStack endpoint using GraphQL would be a great addition (maybe similar to AutoQuery?) If ORMLite could also populate an object graph using a GraphQL query...

I've started working with request batching, which is a really nice feature. Everything works, but there two improvements I'd like to see.

Firstly, for IReturnVoid requests there is SendAllOneWay, but there is no async version of that method.

Secondly, I'd like to be able to specify a http Verb with the SendAll methods. The implementation should select the correct method in the service, both when calling a single request method multiple times, but also for the batched method. Right now the batched service methods always need to be Any(), it would be nice to be able to have Delete(OrderID[] orders).

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.

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.

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

e.g:

db.Save(poco, references: true, deleteMissing: true);

from: https://forums.servicestack.net/t/ormlite-graph-update/1395

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)

Support Azure DocumentDB as an available caching provider for Azure hosts.

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

Currently to send in an integer array as a parameter, I have to use format.

var ids = "ARRAY[1,2,3]";
var sql = "SELECT 1 = ANY[{0}]".Fmt(ids);
Db.Query<Model>(sql);

I would rather use syntax like this:
var ids = new int[] {1, 2, 3};
var sql = "SELECT 1 = ANY(@ids)";
Db.Query<Model>(sql, new { ids });

Add a Trace method to Log/ILog in do verbose logging
