If I'm writing an analyzer to say "stop doing X in xUnit.net v2 because it's been removed in v3", should that be INFO or WARNING by default?

#dotnet #csharp #roslyn #RoslynAnalyzers

@bradwilson It should be an INFO in v2, and upgraded to a WARNING in v3, followed by the inevitable ERROR in v4 when it's been removed.
@anaerin No, it’s actually removed in v3, so ERROR is correct there.
@bradwilson @anaerin then it should be a Warning in the immediately preceding version
