I get this error when trying to compile this code in MonoDevelop for lubuntu.
modelBuilder.Entity<HistoryRow>().Property(h => h.MigrationId).HasMaxLength(100).HasColumnName("migration_id");
modelBuilder.Entity<HistoryRow>().Property(h => h.ContextKey).HasMaxLength(100).HasColumnName("context_key");
modelBuilder.Entity<HistoryRow>().Property(h => h.Model).HasColumnName("metadata");
Error CS0584: Internal compiler error: Method not found: 'System.Data.Entity.ModelConfiguration.Configuration.StringPropertyConfiguration.HasDatabaseGeneratedOption'. (CS0584) (Scar.World)
The code compiles fine in Visual Studio and Windows, so I'm guessing the problem is on Mono's end.
Mono probably does not have the latest EntityFramework assembly included. However we should issue better error message but to diagnose this I'll need a project which reproduces the issue, including reference assemblies.
