Fluent NHibernate: The system cannot find the file specified - asp.net

I'm trying to develop a simple application in ASP.NET MVC WEB API in Visual Studio 2013 Ultimate. Every thing seems to be correct, but I receive this error:

I was inspired by this post.
In my case, this is wrong because of the server
<!--<add name="myConnectionString" connectionString="Trusted_Connection=True;database=Milano_Dev;server=(local);Integrated Security=True" />-->
this was correct
<add name="myConnectionString" connectionString="Trusted_Connection=True;database=Milano_Dev;server=(local)\SQLEXPRESS;Integrated Security=True" />
Basically this depends on your data connection. My code only based on my situation. Hopefully this is helpful to those who still have the answer.

may not work in IIS publish because LocalDb is not intended for product purposes.
For that reason ,Microsoft recommends to use SQLServerExpress for product purpose.
I have also have same ISSUE for SQL Server Compact .Migrating to Sql Server Express does resolve the issues .
you can see the limitation
For your continence
1.Views ->Sql Server Object Explorer
2.Login to Your Data base by Windows Authentication
3.Right click +Extra data tier Application
4.Choose Schema or Data with database with yourName
5.Then Publish Data tier with select yourName file (it works as Backup file) and Target database will be your production.
Then check it works…

AWS RDS SQL Server from EC2 ASP.NET IIS7

I have done the following -
I set up a new EC2 instance running Windows Server 2008 with IIS7.
I set up a new RDS Instance running SQL Server 2008 R2.
I have configured the Security Group for the RDS server to allow SQL Server connections on port 1433 from the EC2 instance.
On the EC2 instance I can connect to the RDS SQL Database by creating a User or System ODBC Connection from Windows. I can also connect from my own computer with SQL Management Studio.
When I try to start up my .NET Web Application I get this error
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)
This is my connection string, I am using Entity Framework and an edmx, Database first.
<add name="EntitiesName" connectionString="metadata=res://*/Models.Model1.csdl|res://*/Models.Model1.ssdl|res://*/Models.Model1.msl;provider=System.Data.SqlClient;provider connection string="data source=myrdsserver.rds.amazonaws.com;initial catalog=VPN;User Id=userid;Password=password;Persist Security Info=True;MultipleActiveResultSets=True;"" providerName="System.Data.EntityClient" />
I've tried everything in the following links but nothing works to allow me to connect.
aws ec2 could not open a connection to sql server
entity framework 5 and amazon rds underlying prodiver failed to open
can't connect to rds instance from ec2 instance
UPDATE:
I created a Windows .NET Forms application that uses the same connection string and Entity Framework and it works. I ran it from the same EC2 instance. It seems that the main difference here is that IIS is not involved with the Windows Form application. I'm not sure how that is keeping the Web application from working.
Here is the stack trace from the web page:

Can't connect to SQL server from asp.net website, receiveing a network path not found error message

The SQL server is Microsoft SQL 2008 R2 running on IIS 7.1.
I'm using an instance of the SQL server and running a different port on IIS(8090) to access the website, as this is not the default website.
My SQL server is working, I've tested it using the following ways.
Connect to it directly from SQL management studio
connect to the server using VPN and using visual studio from my development machine to connect to run the website, no issues encounters and everything works.
Connect to the server using VPN using my test environment through IIS on a virtual machine, everything is working as intended.
The issue occurs from my live server when trying to access the SQL through IIS.
I feel like the issue has to do with IIS, I've checked all the ports and permissions, but I can't figure out why this might be happening
Here is the stack code that i receive.

The error is pretty self explanatory.
"error: 52 - Unable to locate a Local Database Runtime installation. Verify that SQL Server Express is properly installed and that the Local Database Runtime feature is enabled."
The connection string you are using is only valid for your development environment. Depending on how your production environment is setup you have to either make sure your local development environment matches that or adjust your connection string for your production environment accordingly.

The poor man's way to check your connection string (and any firewall issues) outside of code is this:
Go to Control Panel
Find ODBC
Go to System-DSN.
Create a new ODBC connection.
Create a Sql Server one.
Put in your credentials.
Test the Connection.
.........
If that works, then:
If you do this you're running under your own Identity.
Your website may be running under another Identity.
Keep that in mind.
But the ODBC is a quick way to check your credentials.
The error you are getting is basically "I can't connect to the Sql Server as you've defined in the connection string".
......
If you're confident that your credentials are correct, then here is the poor man's way to check for firewall issues.
Get this:
http://www.microsoft.com/en-us/download/details.aspx?id=24009
and "query" your sql server. most likely, you'll ping on port 1433, but that could be different.
........
Firewall setup helpful url:

Your connection lost somehow, maybe because of network issue.
