update System.ValueTuple to 4.4.0-preview1-25305-02 and everything works fine

Isn't there any other way to solve this than have to use the same version that ImageSharp uses? I don't really want to have to look at ImageSharp source code when updating and make sure I use the same version. This is also forcing me to use a preview version of something I don't want a preview version of.

Ummmmmm.... ImageSharp is an alpha?! We are using those versions because we need them to build a performant and usable library.

Those previews will cease to be once Netcore 2 is released so I really wouldn't worry.

[OskarKlintrot]

I know but ImageSharp is forcing me to use other libraries preview versions and I don't want that. And I definitely don't want to look in ImageSharp source code to figure out what is breaking things. I will move to Netcore 2 once it's released so then I don't mind.

@OskarKlintrot At the time ImageSharp get's RC, these libraries will be in an RC state as well. We are building a future-proof API with the newest netstandard/netcore toys, so this is a reasonable tradeoff. "Being in preview" is a transitive relation, so I don't see any problem with using preview packages in a preview library.

I can only qute the disclaimer from our README.md:

ImageSharp has made excellent progress and contains many great features but is still considered by us to be in early stages (alpha). As such, we cannot support its use on production environments until the library reaches release candidate status.

@JimBobSquarePants already noted it and I'm fine with that! I love new toys!
