[import] .NET MusicStore example doesn't work

[quintesse]

Trying to import https://github.com/aspnet/musicstore results in this build error:

We should try to figure out if we can make it work.

It can be reproduced locally using this command:

s2i build -e DOTNET_STARTUP_PROJECT=samples/MusicStore/MusicStore.csproj https://github.com/aspnet/musicstore registry.access.redhat.com/dotnet/dotnet-22-rhel7 dotnet-sample-app

@omajid is this something you can help out with perhaps?

[gastaldi]

@quintesse my guess is that the sample is targeted for .NET Core 3.0 (https://github.com/aspnet/MusicStore/blob/master/samples/MusicStore/MusicStore.csproj#L5) but since my .Net knowledge is near zero, I'll let @omajid answer that 😉

[omajid]

@gastaldi is correct: the MusicStore sample targets 3.0.

@quintesse Can you try using the release/2.2 branch of MusicStore? that should support 2.2 (and 2.1 as well).
