问题 Question: I create a copy of an mdf file with a random name. I inject that name into the connect string used by an EF6 DbContext. It opens fine, I run queries, etc, then I dispose of the context. At this point if I attempt to delete the temp mdf file from the file system I cannot delete it; I get a "file is in use by another process" error. Does anyone know if it's possible to force the connection to drop the lock on the mdf file when the connection closes? Or when the SqlExpress engines

问题 In development, i.e., when using Visual Studio and its built-in IIS Express instance, I have set up my web app to use LocalDB, with the data MDF file located in a directory on my computer but not inside the project directory, e.g., "C:\MyAppData\MyAppData.mdf", not "C:[...]\MyAppProject\App_Data\MyAppData.mdf." This is working just fine when using Visual Studio/IIS Express, and the connection string being used looks something like this: <add name="MyAppEntities" connectionString="metadata=res

问题 I have a table in a SQL database which should have a relation with one of two tables, but not both. My manager solved it by using the ID field of the table Competitor as both primary key and as foreign key for the two other tables. None of the tables have autoincremental IDs. Problem is, when I try to add a new compeitor, it fails unless there is an entry in both of the other tables with the specified ID, which is the opposite of what I want. Here is an illustration to show you how it's done:

问题 I am trying to figure out a way to use a LocalDB in place of SQL for integration testing of EF6 queries (this would allow us to run integration tests on our build server). It seems like I should be able to replicate my database in SQL Express, detach, and import into my test project. I would expect from there I can modify my connection string in my test project to hit the local database file. I am running into a security issue though. I need to get SQL security working to pass in a user id

问题 Is SqlDependency supported in SqlLocalDb ? If yes how to enable it? 回答1: Answering the question about Service Broker in your subject. Service Broker should work fine in LocalDB, but only local queues are available. Remote queues won't work, in either direction (in fact Service Broker queues are bi-directional, so there's no incoming/outgoing queue distinction). 回答2: I dont know exactly but may be below link can be useful for you: http://msdn.microsoft.com/en-us/library/bb934450.aspx 来源： https

问题 I'm developing a Code First Web API using ASP.NET 5 and MVC 6. I can test my models and controllers locally and in Azure using a publish profile, but I want to see if the database is applying some constraints.

问题 I was looking everywhere and still have not found clear answer to this simple question: Is it possible to use SQL authentication with LocalDB, i.e. is it possible to use connection string containing Integrated Security=False ? 回答1: Yes, last I tried it was possible. Just follow the steps from this MDSN article. Keep in mind that it will still be user instance, running under the account that started it, and will be shut down shall the account log out. Also no remote access. 来源： https:/
