Could not find Windows Runtime type 'Windows.Data.Json.IJsonValue'.

[victorhurdugaci]

Try to run MusicStore on Win Server 2008 R2 on CoreCLR. Result:

PS D:\temp\MusicStore-release\MusicStore-release\src\MusicStore> k weblistener
Could not find Windows Runtime type 'Windows.Data.Json.IJsonValue'.
Operation is not supported on this platform.

However, the other samples (in the samples repo) work. It must be some dependency that music store has.

@victorhurdugaci can you set KRE_TRACE=1 and paste the stack trace in here?

Here you go:

kpm restore has the same problem

[Tratcher]

Only the netcore45 (WinRT) target for Newtonsoft.Json has a reference to Windows.winmd. We shouldn't be using that version. I've asked @ChengTian to verify which binary KPM is using.

[davidfowl]

I'm pretty sure it's using the wrong one
