The application: .NET 4.5 C# Uses EF6 with database first approach Supports SQL Server 2008R2, 2012 and 2014 This question is regarding the ProviderManifestToken attribute of the auto-generated edmx file. Depending on which version of the database is used (different developers have different version of the database) to update the model from the database, the value of the ProviderManifestToken attribute either gets set to 2008 or 2012. Until we discontinued support for SQL Server 2005, we made sure that the value of this attribute remained 2005 (see this SO article for more information). I am

I am trying to return a scalar value from a stored procedure. I actually want to return the ID of a newly created record, but I have simplified my problem down to a stored procedure that takes an int and attempts to return that same int . This always returns -1. Thank you very much for your help. Web API Controller call var idtest = dbconn.my_return_int(123); The stored procedure: ALTER PROCEDURE [dbo].[my_return_int] @ID int AS BEGIN SET NOCOUNT ON; DECLARE @return as int SET @return = -999 RETURN @return END The Context generated stored procedure call public virtual int my_return_int

I am implementing DDD with Entity Framework Code First. My Domain Model is persisted as it is without any mapping layer. I am following approach suggested during Tech-Ed by Julie Lerman. Each bounded context maps to different schema within same database. If same entity say, Customer appears across different bounded contexts how do we maintain consistency of data for Customer entity? Only a single bounded context will be the system of record for your entity. If you cannot get away with simply an Id in the other BCs then you can include a subset of the entity (usually not all the properties) as

In the code below, I need to set a foreign key constrant on ParentInfoAddProperties.ParentQuestionAnswersId so that it is dependent on ParentQuestionAnswers.Id (which is a Primary Key). I am attempting to do so using data annotations but Entity Framework 6 wants to create a new Foreign Key column in my ParentQuestionAnswers table which references the ParentInfoAddProperties.Id column not the ParentInfoAddProperties.ParentQuestionAnswersId column. I do not want Entity Framework to create a new foreign key column. I'd greatly appreciate if someone can explain what data annotations or (if

I'm using Microsoft.AspNet.Identity 2.0.0-beta1 and Entity Framework 6.1.0-beta1 (released 11 Feb 2014). I'm getting the following error when I try to change the default type of User ID Primary Key from string to int AND when I try to use custom table names (so User.MyUsers instead of dbo.AspNetUsers): " The entity types 'IdentityUser' and 'ApplicationUser' cannot share table 'MyUsers' because they are not in the same type hierarchy or do not have a valid one to one foreign key relationship with matching primary keys between them. " I can successfully change the default type of User ID PK from

To deal with SQL timeouts I'm trying to use SqlAzureExecutionStrategy ( https://msdn.microsoft.com/en-us/data/dn456835.aspx ) The problem I am running into is it prevents "user initiated transactions" which seem to be the recommended way to implement "with (nolock)" in EF ( http://www.hanselman.com/blog/GettingLINQToSQLAndLINQToEntitiesToUseNOLOCK.aspx , NOLOCK with Linq to SQL ). example code public AspnetUser GetAspnetUserByUserName(string userName) { using (var tx = new TransactionScope(TransactionScopeOption.Required, new TransactionOptions() { IsolationLevel = IsolationLevel
