Unity3D requires .NET version <=4.6 about colourful HOT 4 CLOSED

@hacky97 It looks like your Unity project doesn't support the higher version of C# than 6.0 (unless it can be configured somewhere).

But why do you need to include the source code of the library? Can't you just reference the binaries or the NuGet package?

Hi there,

The "type pattern matching" is a feature of the C# language, not the .NET Framework. Even though the library uses features from a later version of C# (7.3), it can still be used in .NET 4.5 or .NET Standard 1.1, which means you should be able to use it with Unity.

The in and readonly were added recently with the v2 release to eliminate allocations as a performance improvement. See: #43

If you want to use a version without these, just use the previous version, v1.

Thanks for the clarification Tom. I keep mixing c# versions with .NET versions.
Unity won't swallow it however. I set he API compatibility level of Unity 2017.3.0f3 to .NET 4.6 and it simply spits errors about the above syntax.
I guess that's because Unity does not really use .NET, but a forked version that's being kept "up-to-date" on top of Mono.

No, I don't think I really need the source.
The nuget package manager in VS won't fool Unity however, but with the nuget asset from the Unity asset store I was able to download Colourful into the unity project and run a test.
Thanks!

Edit:
Had to add ref keywords to the sample code too:
double deltaE = new CIEDE2000ColorDifference().ComputeDifference(ref color1, ref color2);
(VS shows errors here, but Unity will compile fine)
