I have a problem scaffolding and doing migrations from a class library with multiple DBContexts. I found a command line argument that looks like this for migrations: dnx ef migration add -c Contexts.IndustryContext initial But this doesn't even get by the command line parser. I want all my DBContexts and database stuff out of the main MVC 6 web project and in their own DLLs. Is this possible? What command line magic is required? I was looking for an answer to this question and wanted to provide my solution for ef core 2.0. Microsoft.EntityFrameworkCore.Tools.DotNet needs to be added to each of

I have a model that has some columns defined with default values like table.Column<bool>(nullable: false, defaultValueSql: "1") When I save a new entity in the database using context.SaveChanges() , I noticed that the columns with default values are not included in the insert into query that Entity Framework generates, so the values generated in the database are the default ones instead of the ones I'm passing in the model. Do I have to set up some property in the context to be able to set these properties through code? I'm using EF Core, but I don't know if this is a general behavior of all

I know you can do something like var myObj = _db.MyTable.FirstOrDefault(x=>x.Id==id) and then update myObj property by property that you want to update but is there a better way to update say 6 out of 10 properties of myObj and leave the other 4 alone or have them marked as a way that they are only set once and never updateable from ef core? public class MyObject { public string Id { get; set; } public string Prop1 { get; set; } public string Prop2 { get; set; } public string Prop3 { get; set; } public string Prop4 { get; set; } public string Prop5 { get; set; } public string Prop6 { get; set;

From EF6.1, we have a way of specifying a clustered index on a property public class Person { [Index(IsClustered = true, IsUnique = true)] public long UserName { get; set; } } But this Index attribute does not seem to be in EF Core right now? In EF Core how do you achieve this? From the current EF Core documentation - Indexes section: Data Annotations Indexes can not be created using data annotations. But for sure you can specify that via Fluent API (note the extension methods having ForSqlServer prefix which seem to denote SqlServer specific features): modelBuilder.Entity<Person>() .HasIndex

I'm writing a unit test to test a controller action that updates an EF core entity. I am using SQLLite, rather than mocking. I set up my database like this: internal static ApplicationDbContext GetInMemoryApplicationIdentityContext() { var connection = new SqliteConnection("DataSource=:memory:"); connection.Open(); var options = new DbContextOptionsBuilder<ApplicationDbContext>() .UseSqlite(connection) .Options; var context = new ApplicationDbContext(options); context.Database.EnsureCreated(); return context; and then add an entity to the database like this: private DiaryEntriesController

When I execute a SQL Server stored procedure from Entity Framework Core (v2.0) in my ASP.NET Core project, I get this exception: InvalidOperationException: no mapping to a relational type can be found for the CLR type 'Int32[]' The SQL Server stored procedure code looks like this: CREATE PROCEDURE [dbo].[sp-UpdateProductOrderAndStock] @customerOrderID INT, @qty INT AS DECLARE @customerProductID INT SET @customerProductID = (SELECT CustomerProductID FROM dbo.CustomerOrder WHERE ID = @customerOrderID) SET NOCOUNT ON; UPDATE dbo.CustomerOrder SET CompletedQty = CompletedQty + @qty WHERE ID =
