Include with InvalidCastException exception about entityframework-classic HOT 4 CLOSED

Hello @schuettecarsten ,

Could you provide a full example of this issue?

We tried something similar but we don't get the error:

var products = context.Products.Where(x => x.ColumnInt > 2).Include(x => x.Category).ToList();

You can send it to: [email protected] if you need to keep the source private

Best Regards,

Jonathan

Problem was caused by our own code. We used the following method to initiate a LINQ query, which works fine with EF6, but fails with EFClassic:

/// <summary>
/// Returns an <see cref="T:System.Linq.IQueryable`1" /> that allows to query the database.
/// </summary>
public override IQueryable<TEntity> Query<TEntity>()
{
	ObjectContext objectContext = ((IObjectContextAdapter)this.dbContext).ObjectContext;
	ObjectSet<TEntity> query = objectContext.CreateObjectSet<TEntity>();
	query.MergeOption = this.mergeOption;
	return query;
}

Meanwhile, I moved back to EF6 with EF+ because of too many side effects.
