How to use OrderBy in EntityFramework

implement both EntityFramework 6 and EntityFramework Core side-by-side in a n-tier solution

The EF6 commands don't know how to work with ASP.NET Core projects (they didn't exist when it was written). You'll probably have to unload these projects before running EF6 commands....You may also be able to explicitly specify ...-StartupProject... as the EF6 project to workaround the issue.

using linq to orderBy in list of lists

Regarding OrderBy()...The ...OrderBy()... method returns a collection of items as opposed to ordering in-place, so you would need to set your ...Cars... to that specific value:...entities.ForEach(h => { // This will order your cars for this person by Make h.Cars = h.Cars.OrderBy(t => t.Make).ToList(); }); ...You could potentially handle...

Offset/Fetch based paging (Implementation) in EntityFramework (Using LINQ) for SQL Server 2008

This is possible with ...Entity Framework 6.1.2... and above so you should be OK to use it in your project. The standard Skip and Take methods can't be captured in the same way as others. There are now two additional overload of the Skip/Take methods that take lambdas, so instead of this:...var results = context.MyTable .Skip(10) .Take(5); ...

Creating a database context using the database first approach with entityframework core.

If you are creating tests, do you need a backing Sql database? Would the In-memory provider not serve you better?...options.UseInMemoryDatabase("database-name"); ...For this reason, I'd ditch using the ...OnConfiguring... method, and rely on passing the ...DbContextOptions... to your constructor...Side note, you have to consider ...what... you are ...

EntityFramework Core 2.0 - Add Migration error "The EntityFramework package is not installed"

Using ExecuteSqlCommand and SavesChanges within same transaction with EntityFramework Core

I upgraded from MySql.Data.EntityFrameworkCore/MySql.Data 6.10.1-beta to 6.10.3-rc and it looks like the problem is gone. Since the problem was random I can't be totally sure that the problem is indeed fixed, but so far so good.

How do I restrict the number of columns used in an INSERT when using EntityFramework?

If there are operations that would insert entities that only provide a subset of columns (non-null-able for example) then you can consider using a bounded context with an entity declaration for just those applicable columns. The bounded context is a smaller, single-purpose context for reading and writing data since a single EF context does not supp...

using Max() in Orderby

When you call aggregate methods (Average, Min, Max) in a LINQ query using a non-nullable type, it has no choice but to evaluate it locally....To avoid this, cast your Max value to a nullable type and it will be evaluated in the database. ...Assuming CreateDate is of type DateTime, casting it to DateTime? (nullable) should work. ...Here's what your ...

OrderBy in Include child using EF Core

The result you are trying to return is the ordered list of children. That's not what you want. Instead sort the children then return the parent:...public async Task<Parent> GetParent(int id) { var parent = context.Parents .Include(p => p.Children) .SingleOrDefaultAsync(p => p.Id == id); parent.Result.Children = parent.Resul...

What is the best way to seed data with a lot of information using EntityFramework Core?

You can do multiple data seeds by creating a json file....Create a new method called ...SeedLargData... in your PublicationConfiguration class. ...In this method, get the data in the json file, convert it into ...List<Publication>... , and return it to the Configure method. ... public class PublicationConfiguration : IEntityTypeConfiguration<Public...
