[Firebird-net-provider] [EF] How to map Char(1) to Bool

[Dmitry S. <dim...@gm...>]

Hi,
I tried to use entity framework. In the my DB i have "boolean" column. I use
next domain:
CREATE DOMAIN T_BOOL AS
CHAR(1) CHARACTER SET UTF8
DEFAULT '0'
NOT NULL
CHECK (value in ('0', '1'))
COLLATE UTF8;

I created model from my DB. I see property in the model with type String. I
changed type to Boolean. As result i have exception:
Member Mapping specified is not valid. The type
'Edm.Boolean[Nullable=False,DefaultValue=]' of member 'FILLPIECES' in type
'Prowork.Dal.ASSEMBLY' is not compatible with
'FirebirdClient.char[Nullable=False,DefaultValue=,MaxLength=1,Unicode=False,FixedLength=True]'
of member 'FILLPIECES' in type 'Prowork.Dal.Store.ASSEMBLY'.

I tried to use Integer type for column in the DB. But EF also cannot convert
it to Boolean.
I did small research. And found examples

I looked provider by reflector, class FbProviderManifest. It does not
contain any code for recognizing Char(1). And i agree with this.

Question. How can i customize maping?

Thanks.
