Named argument `allowPrereleaseVersions' cannot be used for a parameter which has positional argument specified

Question

Trying to build NuGet on mono and getting:

error CS1744: Named argument `allowPrereleaseVersions' cannot be used for a parameter which has positional argument specified

running:

xbuild Build/Build.proj /p:Configuration="Mono Release" /t:GoMono || die

question: What is it? Is it bug or am I doing something wrong?

some analyse...

code :

    public void InstallPackage(string packageId, SemanticVersion version)
    {
        InstallPackage(packageId, version, ignoreDependencies: false, allowPrereleaseVersions: false);
    }

error comes from: https://github.com/mono/mono/blob/master/mcs/mcs/ecore.cs#L5324

Answer 1

Yes, it's a bug in mcs compiler. You can use master version or wait for 3.2 update to get the issue resolved.
