What does “Version” mean when viewing reference properties in Visual Studio?
I am currently battling "DLL hell" in Visual Studio 2017. For unknown reasons, I suddenly got a problem with System.ValueTuple, where the error I get is the classic problem that have been asked many times before:
Could not load file or assembly 'System.ValueTuple, Version=4.0.2.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies. The system cannot find the file specified.
I cannot really figure it out, as I have dont think I should have any reference to 4.0.2.0. VS tells me the following:
What I dont get is how the "Version" of the System.ValueTuple says 4.0.2.0, when I have installed version 4.4.0 according to the path of the DLL and according to NuGet Manager.
So, why is it like this?
Ehm, that sounds completely weird =) So, When I install verion 4.4.0, I am really installing version 4.0.2.0 then, in the case of System.ValueTuple. Then I dont get, what is a package version and why does it differ from the assembly verson, that I am actually installing?

That's a question for the producer of the package. Many libraries fix the assembly version to something like 4.0.0.0.

So, 4.40 means very little in this case, and NuGet versions are in most cases then completely off; the actual version of the library can be anything else? I see this discrepancy with a lot (most?) things I install from NuGet etc.

You have installed the version 4.4.0 of the NuGet package that doesn't necessarily contain an assembly with version 4.4.0.0.
