Build failures since a couple of days

Since a couple of days I am experiencing build failures. I cannot imagine what's wrong, since the project builds correctly on my own machine. Can you have a look at please?

I have deleted all failing builds except the last one, which has the exact same build errors as the other failed builds.

Thanks in advance!

    Hi Luk,

    Looks like switch statements (and maybe other C# 7+ features) causes those errors.

    What version of .NET Core do you use locally to build the project?

    global.json is referencing 1.1.13: - isn't it kinda old for switches with lambda?

    Indeed it is quite old. :-/

    I have updated global.json to sdk version 3.1.100, but now it's telling me "MSB4044: The "GetPackOutputItemsTask" task was not given a value for the required parameter "PackageVersion".", which is an error that I avoided in the past by including a global.json.

    Do you have any advice as to how to proceed?

    Try adding PackageVersion element into project file:

    I have tried adding <PackageVersion> to the csproj file, but I get the same result.
