I am developing an Azure website and a WebJob. The development database is an Mdf file. The Mvc app can connect to Azure storage and the database. The WebJob can connect to the Azure storage, but the database throws this:
System.Data.SqlClient.SqlException occurred
HResult=0x80131904
Message=A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible.

Both the Mvc and WebJob share the same connection strings:
Data Source=(LocalDB)\\MSSQLLocalDB;AttachDbFilename=D:\\Projects\\Test1\\Code\\Database\\Test1.mdf;Integrated Security=True;Connect Timeout=30;Encrypt=False
It doesn't make any difference if the Mvc app is running when the WebJob is started.
In the MVC app user secrets, I had to use double slashes, like this:
Data Source=(LocalDB)\\MSSQLLocalDB
In the app.config file for the webjob console app, I had to use single slashes like this:
Data Source=(LocalDB)\MSSQLLocalDB

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

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.

[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

If I create the database using the Console App and then try and open it with the Bridge app the error is

[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'

[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 have an MVC project in which I used Entity Framework code first approach to create my database. The database exists and I can query it from my MVC project without any issues.
Now, I added a console project to the solution. Within this console project I added a reference to my MVC project, added Entity Framework NuGet package and added the connection string from web.config (in the MVC project) into app.config (in the console project).
The connection string is:
<connectionStrings>
<add name="TradeManagerContext" connectionString="Data Source=(localdb)\MSSQLLocalDB; Initial Catalog=TradeManagerDB; Integrated Security=True; MultipleActiveResultSets=True; AttachDbFilename=|DataDirectory|TradeManagerDB.mdf" providerName="System.Data.SqlClient" />
</connectionStrings>
I verified that this is the connection string being used in the console app with this debugging code:
System.Console.WriteLine("ConnectionString=" + db.Database.Connection.ConnectionString);
When my console app attempts to query the database:
var result = db.Trades.Where(c => c.Ticker == "AAPL");
That line throws an exception with message:
Cannot attach the file 'C:\Users\RED\documents\visual studio
2015\Projects\TradeManager\Console\bin\Debug\TradeManagerDB.mdf' as
database 'TradeManagerDB'.
Any ideas on what this exception means and how I can resolve it?

Is it a problem with database or not? I have published the whole site by using Publish button in VS. But may be database is not attached to the cloud web app? I'm not sure. If the problem is in missing database how can I publish database associated with the website so they work together?
The problem is definitely that the website can't find or communicate with the database. There are several ways to do this, but you will need to figure out how you want your database to be hosted - it looks like you're using SQL, so your options are:
SQL Express/LocalDB on the instance that your website is running on
Azure SQL DB (which will be hosted in azure and accessible by your website)
SQL Server hosted in VMs in Azure
Another SQL database hosted elsewhere (on premises maybe) and can be accessed by a hybrid connection
I'd recommend option 2, since it gives you a managed solution out of the box that can scale with your app, but is network addressable, so multiple instances of your web app can share it, it's backed up automatically, etc. etc.
Perhaps share some more information on what you've got already or what you have in mind you're trying to achieve?
I have a MVC4 app that is using a ReportViewer control on a aspx page inside a iframe in my razor view. I followed this answer here: https://stackoverflow.com/a/11055132/876511.
Well this worked ok on localhost but it doesn't when i deploy to server.
First error i got was solved by setting the "Copy Local" property to true of the Microsoft.ReportViewer.WebForms Reference.
Than I got this error on server: "Could not load file or assembly 'Microsoft.ReportViewer.Common". For that i manually copied the dll from "C:\windows\assembly\GAC_MSIL\Microsoft.ReportViewer.Common\11.0.0.0__89845dcd8080cc91" to the bin directory on server.
But now i'm getting this error that i can't figure it out:

What network path? The SQL Server? The rest of the app gets there fine.
Please help me, i have been stuck here for a few days and have no more ideias.
EDIT:
Found out where the error is. In my web.config.release i have this:
<sessionState mode="SQLServer" sqlConnectionString="Data Source=SQLSERVER;User ID=ASPState;Password=XXXXXXX" timeout="120" xdt:Transform="Replace"/>
When i comment out the reportViewer works, otherwise it gives network error. Somethings wrong, probably with the conn string, not sure what.
EDIT2:
Conn string is fine otherwise would not work on the intire app.
My new guess is because its a mix of MVC and Webforms...
The mvc connects ok to the sessionstate server but my webform doesnt. Why?
try
ReportViewerRSFReports.ProcessingMode = ProcessingMode.Remote;
ReportViewerRSFReports.ServerReport.ReportServerCredentials = new CustomReportCredentials("user", "pass", "domain");
ReportViewerRSFReports.ServerReport.ReportServerUrl = new Uri("http://<Server Name>/ReportServer");
ReportViewerRSFReports.ServerReport.ReportPath = "/MYAPP/test";
ReportViewerRSFReports.ServerReport.Refresh();
Replace reportserver.mydomain with your ReportServer.
To a vaoid errors, i normally get the report server url and report path from BID out put windows during report deployment.
I have a Team Foundation Server 2010 setup, in which I have TFS on one server and the databases on another. Recently the server with the databases completely crashed and I had to replace it. I restored the databases from backups, and changed the web.config file for tfs to point to the new server and most everything seems to be working. I can connect to tfs, do checkouts/checkins, create work items, etc. However, I cannot queue builds, and the event log is filling up with errors saying that TfsJobAgent cannot connect to the database. I was wondering if anyone knew if there was a way to configure TfsJobAgent to point to my new database. The event log details are below (TCOSRV1 is the machine running tfs, not the database server). Any help would be greatly appreciated.

Restoring to a new Data Tier (as it's called when you move between servers) needs to follow a quite extensive process to ensure that all settings are properly updated. The procedure would be the same for the process you'd use to migrate from one SQL Server to another.
The full process is explained here:
