EF Core Issue

Post by davisd30 » Mon 23 Oct 2017 17:08

I have created an efml in a new project and when I try to actually do a query against a table, I get the following error:

Method 'Clone' in type 'Devart.Data.Oracle.Entity.OracleOptionsExtension' from assembly 'Devart.Data.Oracle.Entity.EFCore, Version=9.4.348.0, Culture=neutral, PublicKeyToken=09af7300eec23701' does not have an implementation.

For info, this is the query:

Code: Select all

using (var context = new dataModel()) {
return context.TABLENAME.Where(x => x.TableField >= 0).ToList();
}
I have installed the nuget packages and I have the latest dotConnect for Oracle installed on my machine. Any help with this would be appreciated.

dotConnect for Oracle supports only EF Core 1.1.2 at the moment. We will notify you when EF Core 2.0 and .NET Core 2.0 are supported.

As a temporary workaround, please use EF Core 1.1.2:
PM> install-package Microsoft.EntityFrameworkCore.Relational -version 1.1.2

.NET Core 2.0 and EF Core 2.0 are supported: viewtopic.php?f=1&t=36128.

Be aware that starting from Entity Framework Core 2.0 the Scaffold-DbContext functionality (Devart.Data.Oracle.EFCore.Design.dll) is included in the Devart.Data.Oracle.EFCore package.
