NU1109: Detected package downgrade: B from 2.0.0 to centrally defined 1.0.0. Update the centrally managed package version to a higher version.
'Project' -> 'A' 1.0.0 -> 'B' (>= 2.0.0)
'Project' -> 'B' (>= 1.0.0)
A dependency package specified a version constraint on a higher version of a package than restore ultimately resolved. That is because of the direct-dependency-wins rule - when resolving packages, the direct package version in the subgraph will override that of the distant packages with the same ID.
Update the PackageVersion of B to to the higher version of the package.
In the example above, you would change the package reference to B 2.0.0.
