I get following error while generating entity through power tools.
Unable to create a 'DbContext' of type ''. The exception 'The entity type 'Bid' requires a primary key to be defined. If you intended to use a keyless entity type, call 'HasNoKey' in 'OnModelCreating'. For more information on keyless entity types, see https://go.microsoft.com/fwlink/?linkid=2141943.' was thrown while attempting to create an instance. For the different patterns supported at design time, see https://go.microsoft.com/fwlink/?linkid=851728
I am using SQL Server Express 2022. The table has a primary key.
Below is the DDL:
CREATE TABLE dbo.Bid( ID int IDENTITY(1,1) NOT NULL, AppUserID int NULL, EventDateTime datetime NULL, BudgetLow int NOT NULL, BudgetHigh int NOT NULL, EventDescription varchar(max) NOT NULL, CreatedDate datetime NOT NULL DEFAULT GETDATE(), ModifiedDate datetime NULL, CONSTRAINT PK_Bid_ID PRIMARY KEY CLUSTERED (ID), FOREIGN KEY (AppUserID) REFERENCES AppUser(ID) );
It doesn't generate proxy classes. Not sure if it is because of the above error and npm start throws compilation errors.

Hi @Jayesh
Is it possible to share the generated JSON file ? You can find it under
aspnet-core\AspNetZeroRadToolfolder. -

Hi @Jayesh
Thanks. Last question, do you import this entity from an external database ?
-
0
Yes. I connect to SQL Server to read all tables, pick one to generate.

Thanks, than could you also share the generate script for the external table so we can try the same ?
