Humanizer.Core 2.1.0 breaks compatibility with PCL Profile 259

[IlSocio]

Hi,
I was using Humanizer.Core v2.0.1 within a PCL Profile 259
After upgrading to v2.1.0 the project doesn't compile anymore due to the errors below.
It seems you've upgraded Humanizer to the new NetStandard target, but it can't be referenced anymore from a PCL Profile 259

warning MSB3274: The primary reference "Humanizer, Version=2.1.0.0, Culture=neutral, PublicKeyToken=979442b78dfc278e, processorArchitecture=MSIL" could not be resolved because it was built against the ".NETPortable,Version=v5.0" framework. This is a higher version than the currently targeted framework ".NETPortable,Version=v4.5,Profile=Profile259".

error CS0246: The type or namespace name 'Humanizer' could not be found (are you missing a using directive or an assembly reference?)

Hi,

What version of Visual Studio and what version of NuGet do you have?

The Humanizer 2.1 packages require at least NuGet 2.12 when using VS 2013 and at least 3.4 on VS 2015 Update 3.

Humanizer, and any netstandard1.0 library, will install into a PCL 259 project.

I'm using Visual Studio 2015 - Update 3 and NuGet 3.4

According to this link:
https://xamarinhelp.com/dot-net-standard-pcl-xamarin-forms/
".NET Standard Libraries can reference Profile Based PCL’s but a Profile Based PCL can’t reference a .NET Standard Library PCL (not that I know of anyway)."

I just created the a test-solution for this issue:
https://github.com/IlSocio/HumanizerTest

The PCL_NetStandard compiles successfully, while the PCL_259 doesn't

It seems that the statement
".NET Standard Libraries can reference Profile Based PCL’s but a Profile Based PCL can’t reference a .NET Standard Library PCL"
is correct.

Okay, found the root cause. First, that link is wrong. Netstandard does work with PCL 259, you can try installing System.Reactive to prove that.

Second, the real issue is that the wrong TargetFrameworkAttribute is on Humanizer for some reason. The value is .NETPortable,Version=v5.0 when it should be .NETStandard,Version=v1.0. That's why it's failing.

Thank you Oren, understood 👍

I am getting this as well when Using Humanizer with VSTS build host. Its the only package that fails. with error:

"C:\a\1\s\Droid\Fuze.Droid.csproj" (PackageForAndroid target) (1) ->
2016-10-12T20:49:52.6316961Z "C:\a\1\s\Fuze\Fuze.csproj" (default target) (3) ->

2016-10-12T20:49:52.6316961Z Converters\DateConverters.cs(9,7): error CS0246: The type or namespace name 'Humanizer' could not be found (are you missing a using directive or an assembly reference?) [C:\a\1\s\Fuze\Fuze.csproj]

Its working fine when debugging locally so it may be another issue, but this is currently breaking my CI and Auto Deploy builds for beta testing.

This was a bug that they fixed in the latest VS 2015 Update 3 KB. Can you please verify that you have Update 3 and the latest hotfixes for it?

You can see it listed under "Issue 12" of the 9/14/2016 update.

I just checked using the latest Update 3 and the issue is gone! Thank you Oren :)

@onovotny but, it still needs to be .NETStandard,Version=v1.0, doesn't it?

I think the issue with the .targets file inclusion.
