How to replace IBinaryObjectManager

AbpZeroTemplateCoreModule.cs

/* Add registration code to Initialize of your module */

//...
public override void Initialize()
{
    IocManager.Register<IBinaryObjectManager, FileSystemBinaryObjectManager>(DependencyLifeStyle.Transient); //ADD THIS HERE
    IocManager.RegisterAssemblyByConvention(Assembly.GetExecutingAssembly());
}
//...

/* This is not needed if you delete DbBinaryObjectManager from your solution. */
