Foreign Key issue preventing me from updating table in azure sql database (x-post from r/sql)

I'm working on a webapp (C#, MVC 5) that uses an Azure SQL database. I'm also implementing the built in ASP.NET Identity 2.0 system (and I'm sure that's where my issue is).

Probably because of a setting i chose, the credential system insisted on using a local db, rather than my cloud based db (which is fairly useless once my laptop is turned off).

I've migrated all the tables to my azure sql db, set up a new connection string and pointed the IdentityModel at the new connection, rather than the default (and yes, it is a different connection than the regular azure connection which uses entity framework rather than SqlClient)

When I try to register against the local database, everything works perfectly. When I change it to reference the azure database, I get this error:

 SqlException (0x80131904): The INSERT statement conflicted with the FOREIGN KEY constraint "FK_AspNetUsers_ToTable". The conflict occurred in database "PhoenixMachineTracking", table "dbo.Distributor", column 'Dist_ID'. The statement has been terminated. 

I've changed a few things with little success (though this is the newest error; i'm making progress lol) and i'm not sure at this point if the issue is within my connection string (i don't think so), my c# code (I can't find anything that looks wrong) or my tables (it looks like all of my foreign keys are present and correct)

What am I doing wrong? Below are the table creation scripts, as well as my "classes" (not sure if that's what they're called when VS builds them for you from a database)

Distributor Table (users that will be logging in)

 CREATE TABLE [dbo].[Distributor] ( [Dist_ID] NVARCHAR (128) NOT NULL, [Dist_Name] NVARCHAR (256) NULL, [Dist_Address] VARCHAR (50) NULL, [Dist_City] VARCHAR (50) NULL, [Dist_State] VARCHAR (50) NULL, [Dist_Zip] VARCHAR (50) NULL, [Dist_Phone] VARCHAR (50) NULL, [Dist_Fax] VARCHAR (50) NULL, [Dist_Contact] VARCHAR (50) NULL, [Dist_Email] VARCHAR (50) NULL, CONSTRAINT [PK_dbo.Distributor] PRIMARY KEY CLUSTERED ([Dist_ID] ASC)); 

ASP.NET Table generated by visual studio as part of ASP Identity

 CREATE TABLE [dbo].[AspNetUsers] ( [Id] NVARCHAR (128) NOT NULL, [Email] NVARCHAR (256) NULL, [EmailConfirmed] BIT NOT NULL, [PasswordHash] NVARCHAR (MAX) NULL, [SecurityStamp] NVARCHAR (MAX) NULL, [PhoneNumber] NVARCHAR (MAX) NULL, [PhoneNumberConfirmed] BIT NOT NULL, [TwoFactorEnabled] BIT NOT NULL, [LockoutEndDateUtc] DATETIME NULL, [LockoutEnabled] BIT NOT NULL, [AccessFailedCount] INT NOT NULL, [UserName] NVARCHAR (256) NOT NULL, CONSTRAINT [PK_dbo.AspNetUsers] PRIMARY KEY CLUSTERED ([Id] ASC), CONSTRAINT [FK_AspNetUsers_ToTable] FOREIGN KEY ([Id]) REFERENCES [dbo].[Distributor] ([Dist_ID])); GO CREATE UNIQUE NONCLUSTERED INDEX [UserNameIndex] ON [dbo].[AspNetUsers]([UserName] ASC);

Identity Model Class (where the default connection is changed)

 namespace PhoenixProductTracking.Models { // You can add profile data for the user by adding more properties to your ApplicationUser class, please visit to learn more. public class ApplicationUser : IdentityUser { public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager) { // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie); // Add custom user claims here return userIdentity; } } public class ApplicationDbContext : IdentityDbContext<ApplicationUser> { public ApplicationDbContext() : base("PhoenixLogInConnection", throwIfV1Schema: false) { **THIS IS WHERE THE CONNECTION WAS CHANGED FROM "DEFAULTCONNECTION"** } public static ApplicationDbContext Create() { return new ApplicationDbContext(); } }}
