MicroLite 5.0 – Changes to Convention Mapping

In MicroLite 5.0, we are making further enhancements to the convention based mapping which provide even greater flexibility.

Convention Mapping History:

The changes in MicroLite 5.0 are as follows:

ResolveIdentifierStrategy

We have replaced the IdentifierStrategy property with the ResolveIdentifierStrategy method. This means that you no longer have to use the same IdentifierStrategy for every class (or that you can migrate from attribute mapping to convention mapping if this was preventing you from doing so).

By default it will return IdentifierStrategy.DbGenerated but you can override it if you want to specify a different strategy or calculate it based upon the type:

Configure.Extensions().WithConventionBasedMapping(
    new ConventionMappingSettings
    {
        ResolveIdentifierStrategy = (Type type) => 
        {
            if (type == typeof(MySpecialType))
            {
                return IdentifierStrategy.Assigned;
            }

            return IdentifierStrategy.DbGenerated; 
        }
    });

ResolveTableSchema

We have replaced the TableSchema property with the ResolveTableSchema method. This means that you no longer have to use the same schema for every class (or that you can migrate from attribute mapping to convention mapping if this was preventing you from doing so).

By default it will return null but you can override it if you want to specify a specific schema or calculate it based upon the type:

Configure.Extensions().WithConventionBasedMapping(
    new ConventionMappingSettings
    {
        ResolveTableSchema = (Type type) => 
        {
            if (type == typeof(MySpecialType))
            {
                return "MySpecialSchema";
            }

            return "dbo"; 
        }
    });
