Does UWP support LocalDB?
My investigations indicate there are some issues using localdb that I don't experience with SQL Server 2017 Development edition.
I managed to convert a winforms EF-Code First, xaf application to run as a UWP app with the help of this blog
I have Enterprise Authentication set.
When I run the desktop bridge app it creates the database and log file inside
c:\users\kirst
which is my user folder.
However I cannot see the new database in the SQL Server Object Explorer
Clicking Refresh does not help.
A similar app that does not use the desktop bridge will also create the database inside my user directory. In this case I can also see the database in the SQL Server Object Explorer , (localdb)\MSSQLLocalDB
In both cases the connection string is of the form
"Integrated Security=SSPI;MultipleActiveResultSets=True;Data Source=(localdb)\mssqllocaldb;Initial Catalog=mydatabase"
and
providerName="System.Data.SqlClient"/>
I am using Entity Framework 6.2
.Net Framework 4.7.2
UWP Target Version and Min Version 1809 Build 17763
I am running in the VS2017 15.9.4 IDE
At a dos prompt in c:\Program files\Microsoft SQL Server
dir sqlservr.exe /s shows 2 files
one at
c:\Program files\Microsoft SQL Server\130\LocalDB\Binn
and one at
c:\Program files\Microsoft SQL Server\MSSQL14.MSSQLSERVER\MSSQL\Binn
When I query ##Version from within the program, in both cases I see
Microsoft SQL Server 2016 (SP1) (KB3182545) - 13.0.4001.0 (X64)

I experience problems if I try to connect to the database created by my UWP App from my non UWP Program
For example this message about a log file in a folder that does not exist.
This issue is linked
[Update1]
I set up a simple demo of the problem on Github
Set the Startup project to WAPProjThings (The Desktop Bridge) to run it.
In the demo ,if I create the database via the Bridge App as startup then switch to the console app to run, I get
An unhandled exception of type 'System.Data.SqlClient.SqlException' occurred in EntityFramework.dll
Additional information: Cannot create file 'C:\Users\kirst\Things02.mdf' because it already exists. Change the file path or the file name, and retry the operation.
CREATE DATABASE failed. Some file names listed could not be created. Check related errors. occurred
If I create the database using the Console App and then try and open it with the Bridge app the error is
`System.Data.SqlClient.SqlException
HResult=0x80131904
Message=Cannot create file 'C:\Users\kirst\Things03.mdf' because it already exists. Change the file path or the file name, and retry the operation.

[Update2]
I tried to investigate whether a new UWP app - non desktop bridge had the same issue.
To do this I created a solution containing UWP app and a Framework 4.7.2 library.
Nuget let me add Entity Framework 6.2 to both projects. However when I tried to add a reference the library from the UWP I got a message
Unable to add a reference to project
followed by
The method or operation is not implemented
Then I got the Warning
Warning NU1701 Package 'EntityFramework 6.2.0' was restored using '.NETFramework,Version=v4.6.1'
instead of the project target framework 'UAP,Version=v10.0.17134'.
This package may not be fully compatible with your project. App1 C:\dev\XThings2\App1\App1.csproj

I created a new UWP App with a UWP Class library to hold an Entity Framework Core Data Access layer.
However when I tried to run that I got an error indicating that

[Update4]
Back in my original program I have discovered that create database behaviour of the UWP app is different when running in release mode to running in debug mode.
When running in Release Mode via the Bridge Project CheckDatabaseCompatibility does not trigger the xaf DatabaseVersionMismatch event. When running in Release mode in the console project it does. ( This particular behavior occurs for SQL Server Developer edition as well ) Possibly I should write it up as a separate question, but I mention it here in case it is linked.
I have come to the conclusion that localdb is not a supported version of SQL Server for production.
As explained here
LocalDB is a special, low impact version of the SQL Server engine, that is not installed as a Windows Service, but launched (made to run) on demand by the ADO.NET client opening a connection to it. It is intended for single user scenarios, and not for any prodcution use - for production you should use SQL Server Express (or higher)
There is a method to connect UWP to a localdb, you have to use the winforms sql data factory method the issues is although you have access to System.Data.SQLClient, you do not have SqlDataAdapter so you cannot create a user login system. However you can read data from the database and create ObservableCollections. To save you time Adapter Client doesn't work either. I think we have to wait for another update where the all the SQL libraries have been added.
I am running with TFS 2015.3, and SQL Server 2016 SP1, in separate servers.
Recently, I change our production TFS Database from 32 bit to 64 bit (for updating purposes), and I believe we loose some database configuration and permissions.
This week (after the change), we are having some issues with some Jobs, related to Warehouse and Coverage Analysis:

I am guessing this is due to a Database error, but I can't get to the bottom of it. I am using the TFS for automated Builds, and I am not able to see the Code Coverage for the most recent builds. I don't know if it is related. I went to the Application Tier, and Start a Rebuild for the Reporting services, and that works for some of the Build (the Code Coverage appears), but for the newer builds, it is not happening as expected (I run the Rebuild and still the Code Coverage is not shown).
Code Coverage not shown
Do you have any ideas on what is going on with those jobs? How can I solve this?
Thank you so much in advance. If you need any further information, please let me know.
I created a asp.net mvc4 web application in Visual Studio. By default it creates a file Filters\InitializeSimpleMembershipAttribute.cs. I am getting an exception on line 34 when this attribute is invoked:
using (var context = new UsersContext())
{
**if (!context.Database.Exists())**

}
}
The exception happens when I try to run the webapp through IIS, but does not happen when running the app through visual studio F5 or Ctrl+F5 (VS uses iisexpress I think). The ConnectionString is same in both cases and copied below. Also I have configured the apppool in IIS to run under my identity (to match what happens when app is run through VS).

It is possible that the machine config is configured to use a local database connection that needs to be overridden. Try adding
<clear/>
<add name="LocalSqlServer" connectionString="... same as your UsersContext connection string"/>
at the start of your connection strings within your web config
I am using Visual Studio 2012 with SQL Server Express 2012. I created an MVC 4 Web Application using the "Internet Application" template.
I wanted to use an existing database on my instance of SQL Server 2012 Express (as opposed to the template's MDF). I have modified my web.config to point to my local SQL express instance instead and have deleted the template-generated MDF. My Web.Config has:
<add name="DefaultConnection"
connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=Administration;Integrated Security=SSPI;" providerName="System.Data.SqlClient"/>
The stock membership code has a call to initialize the DB:
WebSecurity.InitializeDatabaseConnection("DefaultConnection", "UserProfile", "UserId", "UserName", autoCreateTables: true);
Once the application fires up, the tables get created in the Administration database as I would expect. I can create users and they are populated in Administration. I can populate the roles table and add roles to a user's profile through code and verify that it took. e.g.:
Roles.GetRolesForUser("kristian"); // = string[] { "Administrator" }
But if I try and use role-based authorization like:
[Authorize(Roles = "Administrator")]
I get the following exception:
Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed.
It gives a long nasty stack trace that makes me think it's still trying to create an MDF file:
[SqlException (0x80131904): Failed to generate a user instance of SQL Server due to a failure in starting the process for the user instance. The connection will be closed.]

The line at the bottom of this bundle of joy makes me think it's related to the now-deleted MDF ('System.Web.DataAccess.SqlConnectionHelper.CreateMdfFile'). Am I correct in this? Or is the authorization implemented by the template just incomplete?
If someone else has dealt with this or knows why my attribute usage is failing I would greatly appreciate the help.
I had this same problem. It appears to be related to not initializing SimpleMembership properly. Try making sure that [InitializeSimpleMembership] is used or directly call Database.SetInitializer<UsersContext>(null);
I'm having some trouble getting the code to work from the book "Pro ASP.NET MVC Framework." I'm on page 96 for those that may have worked through this book before. When I run the code I get the following:

InnerException:
All my code builds fine with no errors and it appears to be identical to the book. However, I can't get this to work. I'm an old school asp guy so this is all new to me.
The error is in the database. Either the connection string you have provided points to the wrong database, or the database you are using is missing the table "Products", which is expected to be there.
Since it looks like you are using an SQLExpress database, I might guess that you haven't setup the tutorials database - the program is trying to read from whatever SQLExpress database you already have setup on your machine.
Problem solved!
David you pointed me in the right direction...thanks!
I swapped out the following on my connection string:
OLD:
Server=.\SQLEXPRESSADV.SportsStore;Trusted_Connection=yes;"
For the one below and it works now.
NEW:
Data Source=.\SQLEXPRESSADV;Initial Catalog=SportsStore;Integrated Security=True;Pooling=False
