May I ask a question about Firebird .net provider 2.5.1.
I am using Firebird 2.1
The OS is a Vista Business
I am able to create datasets and lists or grids that show data but it gives
errors when I try to create an ADO.NET Entity Data Model.
For example: I add to the model only one table with just two columns (AREA_ID
integer, AREA_DESC varchar(30)).
The table is added in the model but it gives errors like the ones bellow
Message 1 The data type of the column 'AREA_ID' is not supported so the column
'AREA_ID' in table 'Firebird.Firebird.AREAS' was excluded.
C:\Users\i2suser\Documents\Visual Studio
10\Projects\WpfTest1\WpfApplication1\Model1.edmx 0 1 WpfApplication1
Message 2 The column 'AREA_ID' on the table/view 'Firebird.Firebird.AREAS' was
excluded, and is a key column. The remaining key(s) were used and table/view
has been created as read-only. C:\Users\i2suser\Documents\Visual Studio
10\Projects\WpfTest1\WpfApplication1\Model1.edmx 0 1 WpfApplication1
Error 3 Error 75: Key Part: 'AREA_DESC' for type AREAS is not valid. All parts
of the key must be non nullable. C:\Users\i2suser\Documents\Visual Studio
10\Projects\WpfTest1\WpfApplication1\Model1.edmx 7 7 WpfApplication1
Error 4 Error 75: Key Part: 'AREA_DESC' for type AREAS is not valid. All parts
of the key must be non nullable. C:\Users\i2suser\Documents\Visual Studio
10\Projects\WpfTest1\WpfApplication1\Model1.edmx 20 11 WpfApplication1
So, may I ask if the .net provider supports EDM in Visual Studio 2010 / .net 4
? Or, am I doing something wrong ?
Thanks,
Kostas Seferis
