Can I specify the filename for a localdb database in entity framework 5?

If I'm using Entity Framework 5 with LocalDb, is there a way of specifying the filename of the database in the app.config/web.config file? On further investigation it looks like it is really simple, but isn't clear when reading the docs. First of all you need to have the entity framework part of the configuration <entityFramework> <defaultConnectionFactory type="System.Data.Entity.Infrastructure.LocalDbConnectionFactory, EntityFramework"> <parameters> <parameter value="v11.0" /> </parameters> </defaultConnectionFactory> Once you have that, you then need to specify your connection string.

Purpose of ProjectsV13 LocalDB instance

According to this answer , SQL Server Data Tools uses a private LocalDB instance ProjectsV13, which you're not supposed to use for your own applications. Instead, you should use MSSQLLocalDB or your own private instance. Is this documented anywhere? What does SSDT use its private instance for? (I don't see anything in mine.) Is a private LocalDB instance basically spinning up a second copy of SQL Server? On the surface, it sounds rather resource intensive to have a dedicated database engine just for tooling metadata. How resource intensive is this really? Does it have a perf impact on starting

How can I specify to use SQL Server LocalDb 2014 rather than SQL Server LocalDb 2016 in the connection string?

爱⌒轻易说出口 提交于 2019-11-30 07:35:54
Our application uses SQL Server LocalDb 2014 as the database engine. The connection string we use is "Data Source=(localdb)\MSSQLLOCALDB;Initial Catalog=OurDatabase;MultipleActiveResultSets=True;Integrated Security=True;AttachDBFilename=|DataDirectory|OurDatabase.mdf" Now, on just one of our computers, it has VS 2015SP3 and the latest version of the SQL Server objects installed, our application starts using SQL Server LocalDb 2016. This is undesirable as we exchange back-ups of the database files regularly between computers and now the back-ups that are made in the LocalDb 2016 format cannot

SQL LocalDb Automatic Instance Startup Failure when called from Visual Studio 2013, but not SQL Server Management Studio

Per MSDN Docs: http://msdn.microsoft.com/en-us/library/hh510202.aspx LocalDB supports two kinds of instances: Automatic instances and Named instances. I suspect this has something to do with my problem, so I am wondering if anyone knows how something like this gets automatically created. If I can quote from the docs, "One automatic instance of LocalDB exists for every version of LocalDB installed on the user’s computer." Here is a copy of the relevant section in the above link: Automatic instances of LocalDB are public. They are created and managed automatically for the user and can be used by

How to set up LocalDb for unit tests in Visual Studio 2012 and Entity Framework 5

We have a Visual Studio 2012 ASP.NET MVC project using Entity Framework 5. There are some unit tests that depend on a database. Setting up the app.config file in the test project to use a central SQL Server database works fine. However, it would be much nicer to use a LocalDb, so that each developer has his/her own database when running the tests. Especially since we would like to have the tests set up to DropCreateDatabaseAlways when running. However, I can't get the setup to work. If I try this in app.config: <add name="TestDb" connectionString="Data Source=(LocalDb)\v11.0;Initial Catalog

How to detach a LocalDB (SQL Server Express) file in code

这一生的挚爱 提交于 2019-11-29 18:29:52
问题 When using LocalDB .mdf files in deployment you will often want to move, delete or backup the database file. It is paramount to detach this file first as simply deleting it will cause errors because LocalDB still keeps a registration of it. So how is a LocalDB .mdf file detached in code? 回答1: I have same issue and was thinking of how to deal with it. There are 2 approaches. (1) Detach at the end of (or during) working with database I didn't find the way to close connection in LinqToSQL , but

How to protect SqlLocalDB database file with custom password

I have designed a software using SqlLocalDb v11.0 instance. The database will be on user's machine ( .mdf file). I was using SQL Server CE before. In SQL Server CE my database is protected by a password with "Encryption Mode = Engine Default" Is there any way to protect SqlLocalDB? I know there is a way using named instances, as in the link https://msdn.microsoft.com/en-us/library/hh510202(v=sql.110).aspx Is there any way to associate password with LocalDB .mdf file. So that any other can not open it? If you mean protecting files from user, I think the answer is No, you can't. a user can copy
