Stumped trying to connect IIS 7 to my localdb running inside of Visual Studio 2015

For the life of me I am unable to connect to my localdb hosted database created in Visual Studio 2015 to my local IIS 7 instance running on the same machine. IIS Express works fine but when I wanted to test things as a user outside of my network I dabbled with a Local copy of IIS.
I have tried everything from ensuring the app pools have the right privileges, that my connection strings are accurate and just about every thing else I have found on the web but I cannot for the life of me get this working.
The error I am getting is the following: 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 get a local application data path. Most probably a user profile is not loaded. If LocalDB is executed under IIS, make sure that profile loading is enabled for the current user.
)

Any other details needed to help troubleshoot ask and I will provide.
Thank you in advance for reading.

SQL Server error: 50 when trying to add .mdf file to App_Data

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"

Which are necessary steps to connect to an Azure SQL database in Visual Studio or SQL Server Management Studio?

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. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 53)
The network path was not found
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.

Sql Server Connection Error in C# app

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

Visual Studio 2010 SQL Developement Server stopped working

I was making minor modifications to a view in my ASP.NET MVC 3 C# application when all of a sudden the application would no longer run. The error message is as follows:
System.Data.SqlClient.SqlException: 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: Shared Memory Provider, error: 40 - Could not open a connection to SQL Server)
Upon close inspection of the server explorer I noticed that all database connections are no longer working. I cannot expand any of the connections to view the tables and data I previously generated within. When I attempt to, there is a pop-up window that is generated that repeats the exact same error as above.
It is important to note that I was not making any modifications to any portion of the application that pertains to a database. I was rearranging some of the visual components of a view in my application when all of this occurred. I had just recently restarted my computer and had made no other modifications since that time.
At first I thought that somehow SQL Express had overwritten my development environments version of SQL Server and began to reinstall SQL Server Express. The installation fails every time now. There is no specific error. Windows generates an error message saying that the setup application "stopped working" and hangs until closed.
I have tried several different versions of the SQL Server Express installation package, and they all result in the same error happening at different points in the installation process. To be clear, I'm not even sure SQL Server Express is the problem. I don't know why it would be since I'm using the SQL Server edition that is built into Visual Studio 2010.

Is the SQL service running? Check under SQL Server Configuration Manager.
Yes, another life saved.
Run-sqlservermanager11.msc, right click and start.

Is the SQL service running? Check under the SQL Server Configuration Manager.
I assume you've already tried to repair install, to uninstall and to restart your computer, pray then try again?

Are you databases remotely deployed? Because it is possible that the network is down.
Secondly, check in the we.config file if you have specified the correct credentials. Try to log in through SQL Server Management Studio.
One more thing: Stop the SQL Server service, and start it again. Or you can reboot the system.
