The length of the definition field seems limited to 260 characters (I guess filename length?)
For many classes from the Enterprise Framework 6, the definition field is too short to show all classes and interfaces. There are for sure a bunch of libraries with much longer definitions.
For example the DbContext class:
class Microsoft.EntityFrameworkCore.DbContext : System.Object, System.IDisposable, System.IAsyncDisposable, Microsoft.EntityFrameworkCore.Infrastructure.IInfrastructure<System.IServiceProvider>, Microsoft.EntityFrameworkCore.Internal.IDbContextDependencies, M
Whatever comes after the IDbContextDependencies... I have no idea.
