This test was breaking in my timezone because it's already DST in Tokyo, but not here. I wish that was the lead in to a joke or something but...yeah no. FML.

This is a static init...it's not going to vary. We should probably drop net45 and just delete this whole concept from the code.

There's a VS runner bug in 2.4.0-beta.1, see https://github.com/xunit/xunit/pull/1643

* Add netstandard2.0 target to SE.Redis projects

Two new conditional compilation constants are introduced:

* FEATURE_PERFCOUNTER - supported in net45 and net46
* FEATURE_THREADPOOL - supported in net45, net46, and netstandard2.0

* Add netcoreapp2.0 target framework to test projects

* Replace CORE_CLR conditional compilation symbol

with built-in NETSTANDARD1_5 or NETCOREAPP1_0 since now netstandard2.0
is also supported.

* Remove unnecessary conditional compilation constants

* Give defaultClientName a value when it is null
This prevents calling TryGetAzureRoleInstanceIdNoThrow() repeatedly in the null case.
* Upgrade xunit to 2.3.1
* Upgrade xunit to v2.4.0-beta1 to work around https://github.com/xunit/xunit/issues/1601
* Move xUnit to 2.4.0-beta.1.build3958

The .NET Core documentations states that hte SetMinThreads Method is available in .NET Core 1.0+. Updated instructions to identify that. Also updated the link to the new documentation.

Looks fine and valid to me, thanks! Makes perfect sense.

Note: tests folder is still different until we merge PRs and change directory structure here to /src, /tests, etc.

* Removed invalid call to SetRequestSent for IMultiMessage

* Improved (corrected) check logic.

* Disable Stop-Words added

* DisableStopWords enum value updated

* Tag feature added

Except for redisearch.io and www.ideawu.com, because they don't have an https endpoint atm.

* Added a note on .NET Core and thread counts

It threw us a bit when we saw this exception but not the same information :)

* Added details for .netstandard 2.0

* Update Configuration.md

* Alphabetical order.

It was unreachable because EndOfStreamException is inherited from IOException.

GeoTests.cs converted to UTF-8, .idea dir added to .gitignore.

Also adds Sentinel to appveyor, we hope. Or this will fail miserably.

These get overwritten when run, so they're ignored via:
git update-index --assume-unchanged RedisConfigs\Sentinel\sentinel-26379.conf

To make changes that should propagate to others:
git update-index --no-assume-unchanged RedisConfigs\Sentinel\sentinel-26379.conf

If we're AddressFamily.Unspecified, that'll always error. Assume IPv4 (as we did before).

This fixes connecting to IPv6 servers.
