From 14284b64c2dca810255a0cecd940ead083dc4356 Mon Sep 17 00:00:00 2001
From: Bjarke Berg <mail@bergmania.dk>
Date: Fri, 29 Jan 2021 10:30:28 +0100
Subject: [PATCH 009/167] Bugfixes.. - ModelsBuilder: Inject
 PublishedValueFallback into static Mixins - ModelsBuilder: Throw exception if
 compiler can't compile the code - CheckIfUserTicketDataIsStaleAttribute:
 Scope issue - Ambiguous Actions: Couldn't determine the action when empty
 arrays was passed. Fixed by using more v8 like solution. (Still stupid the
 client not just have different endpoints) - Fixed issue with reading the body
 from post requests. Often we where not allowed to seek in the stream. -
 UmbracoHelper: Made available on UmbracoViewPage - Client entity.resource.js:
 Don't ask server when getByIds has 0 ids. - Client content.resource.js:
 Renamed endpoint GetEmptyBlueprint to avoid ambiguous action name

Subject: [PATCH 021/167] Changes the umbraco route values to use http features
 intead of in route values which is much nicer, fixes the redirect to page
 result, tests a surface controller POST and it works, ensures the routing
 takes place before the form check, removes a bunch of old code

Subject: [PATCH 030/167] Changes how controllers are discovered, re-uses
 aspnetcore to do this, rely directly on the resolved
 ControllerActionDescriptor since this is how routing works anyways and also
 saves future lookups (perf), gets the UmbracoPageResult 'working' - at least
 to proxy a controller execution but now we need to do the model state
 merging, etc...

Subject: [PATCH 146/167] Netcore: Align namespaces (#9801)

* Rename Umbraco.Core namespace to Umbraco.Cms.Core

* Move extension methods in core project to Umbraco.Extensions

* Move extension methods in core project to Umbraco.Extensions

* Rename Umbraco.Examine namespace to Umbraco.Cms.Examine

* Move examine extensions to Umbraco.Extensions namespace

* Reflect changed namespaces in Builder and fix unit tests

* Adjust namespace in Umbraco.ModelsBuilder.Embedded

* Adjust namespace in Umbraco.Persistence.SqlCe

* Adjust namespace in Umbraco.PublishedCache.NuCache

* Align namespaces in Umbraco.Web.BackOffice

* Align namespaces in Umbraco.Web.Common

* Ensure that SqlCeSupport is still enabled after changing the namespace

* Align namespaces in Umbraco.Web.Website

* Align namespaces in Umbraco.Web.UI.NetCore

* Align namespaces in Umbraco.Tests.Common

* Align namespaces in Umbraco.Tests.UnitTests

* Align namespaces in Umbraco.Tests.Integration

* Fix errors caused by changed namespaces

* Fix integration tests

* Undo the Umbraco.Examine.Lucene namespace change

This breaks integration tests on linux, since the namespace wont exists there because it's only used on windows.

* Fix merge

* Fix Merge
