When abp framework introduced mongo, suggesting warehousing solution interface is not registered

Dependson incorporated in the application layer side storage location of the interface PersonTaskDataModule 
 [The DependsOn ( 
        typeof (AbpServiceNetCoreModule), 
        typeof (AbpServiceCommonModule), 
        typeof (PersonTaskCoreModule), typeof (PersonTaskDataModule), 
        typeof (AuthorizationModule), 
        typeof (AbpAutoMapperModule))] 
    public class PersonTaskApplicationModule: AbpModule 

this introduces mongodb storage mode call abp can be properly used. 

At present, some documentation abp framework does not describe the details of this one, and I hope this can help you to introduce the issue of mongo in the abp.
