EF 5 Beta 1 Code First - Sequence contains more than one element - entity-framework

I am attempting to upgrade my solution from the June 2011 CTP of EF Code First to EF 5 Beta.
I now have the following problem:
After creating an instance of the context, I get the exception listed below when I try and query the context.
It seems as if between the two versions of EF, something has changed whereby it is now having a problem with dealing with the configuration but I am at a loss in terms of where to start looking.
Many thanks in advance for any help.
Paul.

This is a known bug in EF5 Beta 1. We are going to fix this in Beta 2, which will be dropping within the next couple of weeks.
The bug only affects Independent Association (associations where the FK does not exist in your CLR classes) so you can workaround by switching to FK associations.

How to create a LocalDB instance for NEventStore

I'm trying to use LocalDb with NEventStore but, even though I think I have set-up the database correctly, I keep getting the following exception:
NEventStore.Persistence.StorageUnavailableException: Invalid object name 'Snapshots'.
In code I configure NEventStore to use the database like this:
this.EventStore = Wireup.Init()
.LogToOutputWindow()
.UsingInMemoryPersistence()
.UsingSqlPersistence("DefaultConnection")
.WithDialect(new MsSqlDialect())
.UsingJsonSerialization()
.LogToOutputWindow()
.Build();
I have the following database connection in my web.config file:
<add name="DefaultConnection" connectionString="Data Source=(LocalDb)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\MyDatabase.mdf;Initial Catalog=MyDatabase;Integrated Security=True" providerName="System.Data.SqlClient" />
And using Visual Studio I've added an SqlServerDatabase (MyDatabase.mdf) to the App_Data folder of my Asp.net MVC 5 project. NEventStore seems to be able to open the database (if I remove MyDatabase.mdf from my project I get a different exception). But it seems its unable to initialize the database correctly. When I browse the database, after running into the error message, I see that no tables have been created.
What makes this extra strange is that, if this document is correct, Snapshots should be the second table made. So it seems it has no problem creating the first one.

I literally found the answer two minutes after looking. But since I had a hard time Googling this answer I think it would be nice to place the answer here, instead of deleting the question.
I forgot to initialize the storage engine. I overlooked it because of the fluid syntax. The correct way to let NEventStore initialize the database is by including the InitializeStorageEngine method after you have selected the database type:
this.EventStore = Wireup.Init()
.LogToOutputWindow()
.UsingInMemoryPersistence()
.UsingSqlPersistence("DefaultConnection")
.WithDialect(new MsSqlDialect())
.InitializeStorageEngine() // The oh so important line!
.UsingJsonSerialization()
.LogToOutputWindow()
.Build();

Data Entities Add Range quit working

Like the title suggests I have a small program that has been running in production for the last 3 months. Last week it started to error out on an AddRange line with this error message:
"Message=Keyword not supported: 'file'."
And nothing in the inner exception. Here is the offending function where I can no longer get to the SaveChanges() line.
private static void SaveToDB(List<MarketNew> inMarketNews)
{
proxy.MarketNews.AddRange(inMarketNews);
proxy.SaveChanges();
}
cheers

edit-
If I try to manually add them one at a time I still receive the following exception.

InnerException:
The exception indicates that there is a problem with your connection string. While the program itself may not have been changed in months, can you confirm that the config file (or however you set your connection string) has not been changed?
If you still can't find it from this, I would suggest you check out the value of the connection string at runtime (e.g. put a breakpoint on the AddRange line, and look at proxy.Database.ConnectionString). I suspect you'll find the "file" keyword in the connection string.

"The given key was not present in the dictionary." when adding Association to Entities

Using EF6 / VS 2013, I have created an ADO.NET Entity Data Model. This model uses three views, stored in SQL Server, to prepare the data in a suitable form from an existing system. One for Users (vw_Users), one for Roles (vw_Roles) and a cross-reference/association view (vw_UserRoles).
When the User and Role entities are mapped, the application compiles and executes without issue. However, when I add the Association between User and Role and map it to the vw_UserRoles view, I get an EntityCommandCompilationException with an inner exception, KeyNotFoundException {"The given key was not present in the dictionary."}.
An exception of type 'System.Data.Entity.Core.EntityCommandCompilationException' occurred in mscorlib.dll but was not handled in user code
Additional information: An error occurred while preparing the command definition. See the inner exception for details.
To me it just feels like a bug but I am new to a lot of the EF and it could be to do with connecting to views. Out of interest I implemented this trick to treat the view as a table but it made no difference.
UPDATE #1: I created a new web application with a new SQL Server database. I created the underlying tables with relationships and a view for each table. When I create a entity model based on the tables, I have no problems -- even with the association. When I created a model from the views, I get the KeyNotFoundException. Note: I have corrected the keys and added and mapped the association on the second, view-based model. You can download the project from here - http://sdrv.ms/1eZ7ytp
UPDATE #2: I have logged this as an issue with MS # Codeplex - https://entityframework.codeplex.com/workitem/1777
I'm still stumped on this one and am really keen to complete this using a series of views. Any thoughts? Please....?

I have the same issue. When the model was originally created the EF version used was 5. Now using VS 2012 and EF6. Don't want to roll back to EF5.
UPDATE: Identified as a regression as part of the initial EF6 release.
Thanks for reviewing the project for me, #Pawel. If you can put a comment on the CodePlex issue, that would likely aid in it getting some priority. http://entityframework.codeplex.com/workitem/1777
On one hand I am happy the issue is repeatable and a likely bug. On the other hand, I just want to get on with doing this in EF 6. I have resorted to completing this in VS 2012 using EF 5 for the meantime. I will update if I uncover anything else.

InnerException:
What am I doing wrong?
Your code works in our environment:
a) dotConnect for PostgreSQL v 6.7.287
b) SharpMap v1 RC3
c) Postgis 2.0
d) DDL:
CREATE TABLE monitoring_object
(
id serial NOT NULL,
geometry geometry,
last_changed_by character varying
);
Please give us the following information:
1) the version of your SharpMap. Be aware that current release of dotConnect for PostgreSQL supports SharpMap 1.0 RC3 ( http://sharpmap.codeplex.com/releases/view/106717 ). The 1.0 Final version will be supported soon
2) the version of your Postgis. It should be of the 2.0 (or higher) version. You can check it by executing "select postgis_version()" in the database
3) the DDL script of your monitoring_object table
4) if possible send us a small test project
The corresponding Devart documentation is available at http://blogs.devart.com/dotconnect/enhanced-entity-framework-spatials-support-for-oracle-mysql-and-postgresql.html .

Entity Framework Migrations - support for dynamic connection string

I can't make the migrations work for a specific scenario.
Our application uses two different models. The first is for the main database and there, the migration is working fine. The second model is for our customers databases which are specific for each customer (of course...) but all share the same model.
So, in the application (ASP.Net MVC 3), we identify the customer using the route and all customers are hosted in the same application. So, for each request we pass a key to our customer model dbContext constructor and with that key we recover the connection string through a simple helper method.
The application is working fine but not the migrations since I found no way to pass the key in the Package Manager Console.
I tried to create my own IDbConnectionFactory but it is not taken into account.
If I try an update-database command with the connection factory I get the following error which is normal since no key is passed but I can see that my connection factory is kicking in (EFCustomerModel.EFConnectionFactory):

But when I try to pass in my key using the -ConnectionString parameter, then my connection factory is ignored and I get the same error:

So, is this an unsupported scenario in the migrations or there is another way to pass in my key or maybe there is another way to generate my connection strings?
You should be able to pass a key to your custom connection factory with the -ConnectionStringName parameter. This parameter would be passed to the CreateConnection method.
Another possible solution would be to call DB migration from your code:
var configuration = new Configuration();
configuration.TargetDatabase = new DbConnectionInfo(
"Server=MyServer;Database=MyDatabase;Trusted_Connection=True;",
"System.Data.SqlClient");
var migrator = new DbMigrator(configuration);
migrator.Update();
