My objective was to make a database for general store. Information was very scattered about how to create database and why in that way. So i selected SQL Server Express.
Application was made in C# Visual Stduio 2012. Database was created with SQL management Studio. To connect the application with database i used serverexplorer in visual studio and assigned ./sqlexpress
Now the problem is that database works fine on my pc but when i deploy application on the clients pc it says
A network-related or instance-specific error occurred while
establishing a connection to SQL Server. The server was not found or
was not accessible. Verify that the instance name is correct and that
SQL Server is configured to allow remote connections. (provider: SQL
Network Interfaces, error: 26 - Error Locating Server/Instance
Specified)
Connection String Used connectionString = "Data Source=.\\SQLEXPRESS;Initial Catalog=pos;Integrated Security=True";
Where i went wrong ? Is database also deployed with published app or i have to do some other steps ? Will i have to install SQL server on client pc too?
Note: The application is local. i don't need to transfer data via internet.
Let me know according to your experince what is the right way to attach,create and deploy database the right way for this small project because internet is full of guide but there is no where mentioned properly why the specific method is adopted etc
I solved the issue by download sql server management studio on client pc. I just made a backup of database form my management studio and restored that backup file from clients management studio. And now everything is working

I was creating a web site project in Visual Studio 2015, created an App_Data folder and tried to add a SQL Server database file.
This error occurred:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections.
(provider: SQL Network Interfaces, error: 50 - Local Database Runtime error occurred. Cannot create an automatic instance. See the Windows Application event log for error details.
I am using Microsoft SQL Server 2014 (v12.0). I checked the connection in SQL Server Configuration Manager, the server connection is enabled, my TCP/IP port is set to 1443, my Firewall is set for the connection as well.
I am able to connect to my server from Visual Studio Tools/Connect to Database Option, it's able to connect either to my server or to a local database. When I test my connection from there, it works.
I also see the connection is enabled and running from server explorer, and when I drag and drop an SQL DataSource Wizard from my ToolBox to an aspx page, the wizard sees the database and is ready to import it as well.
I also have tried double checking the connection under services.msc from cmd and it's all up and running.
Yet, when I want to right click and add a SQL Server database file to my App_Data folder, this error comes up.
I have no idea what is wrong.
Try to use (localdb)\mssqllocaldb as server name to connect to the LocalDB automatic instance. for more information read this article: http://www.sqlcoffee.com/SQLServer2014_0010.htm
Just for documentation (and SQL Express users having the same problems)
1. Check that SQL Express (master-) database exists and is reachable
In Server Explorer => Data Connections => Add Connection
(LocalDb)\mssqllocaldb
(LocalDb)\v12.0
(LocalDb)\v11.0
For further SQL Express problems see:
SQL Network Interfaces, error: 50 - Local Database Runtime error occurred. Cannot create an automatic instance
2. Configure Default Connection in Visual Studio
If you upgraded SQL Express the wrong connection string still resides in the VS configuration
Tools => Options => Databas Tools => Data Connections -> "(LocalDB)\mssqllocaldb"
I am using Visual Studio 2013 with update 5. I created a SQL database on Azure.
Now I am trying to connect to it in VS and SQL Server Management Studio, but I get this error
Error : Connect to Server
Cannot connect to MyServerName.database.windows.net.
ADDITIONAL INFORMATION:
A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible.

Before connecting to Azure SQL I have taken these steps:
Added machine's IP in SQL Azure firewall
Opened port 1433 by adding a new outbound rule in firewall on my local machine
I want know which step I missing in whole process.
Well. This is hapenning because tha address you're using isn't ok to access. Try to connect through the IP, and make sure you're using the PUBLIC IP/DNS. Try to open the firewall on both sides. That's all that I could help you with the information error reported for you. The conection string that you're using is not ok or not accessible.
VS2013 and above has a decent cloud explorer screen, I'd recommend navigating to the resource through that first. You can also use the Server Explorer to navigate to the right resource and open in in SQL Server Object Explorer. That will at least eliminate if it's an issue with your stored credentials.
I've created an ASP.NET MVC4 project in Visual Studio 2013 and I've created and attached a local database using SQL Server Express. I will deploy this project to a Cloud service, how do you publish the database to Cloud service?

EDIT: I have created my Database using Visual Studio 2013 in Server Explorer Window, right click on Data Connections and Create New SQL Server Database... after connect successful this database in my project on localhost. Now, I have deployed my project to Azure Cloud Service, but How do I upload the database in the same Azure Cloud Service?
EDIT 2: I've created my database in App_data, on localhost works fine but when I deploy to Cloud Service, shows the following error when program calls the database:
A network-related or instance-specific error occurred while
establishing a connection to SQL Server. The server was not found or
was not accessible. Verify that the instance name is correct and that
SQL Server is configured to allow remote connections. (provider: SQL
Network Interfaces, error: 26 - Error Locating Server/Instance
Specified).
My connection String is:
this.ConnectionString = #"Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\MidSapDB.mdf;Integrated Security=True;User Instance=True";
When you right click on the project you should see publish. Click on publish it will take you to a page where you shall able to configure IIS, database etc. Please let me know if you know more details. It should be very straightforward.
I have developed an inventory system in C# ,database used is SQL server .Now my problem is how to deploy my project with database and run it on client's machine i have 1 more week remaining in delivering this project .I tried many blogs and sites but all in vain and i did not get any good resource which clearify me all this scenerio.The current publishing process does not have a database file and showing me an error :

Please any suggestions would be highly appreciable?
I am using Visual Studio 2013 and SQL Server 2012!
By default, SQL Server have network access disabled after a fresh install. You need to use the SQL Configuration Manager to allow remote connections to the instance.
See this post:

If after this you still can't connect, verify that SQL Server ports are not been blocked by the machine firewall.
I am developing an application that contains a small SQL Server database File.
On my machine, it works fine. I am using Microsoft Visual C# Express 2010.
I have sent my project to a colleague. He is using the same software. And he has placed the database file in the same place (c:\folder\db.mdf). However, he gets the following error when trying to open the connection:
System.Data.SqlClient.SqlException was unhandled
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. Verify that the instance name is correct
and that SQL Server is configured to allow remote connections.
(provider: SQL Network Interfaces, error: 26 - Error Locating
Server/Instance Specified)
How can I help my colleague get connected? He is on the other side of the country.
There are several ways to copy a database from one machine to another - the way I normally do it is to use SQL Server management studio to do a backup on the "from" and then to do a restore on the "to".
