I am trying to change the app.config dinamically on my build server, I created a Configuration called Build, and I have these 4 .config files.
this is my app.config
<connectionStrings>
<!--configSource="connectionStrings.config"-->
<add name="TestContext" connectionString="Data Source=ServerDoesNotExist;Initial Catalog=TestDb; Integrated Security=true" providerName="System.Data.SqlClient" />
</connectionStrings>
and on my app.build.config
<?xml version="1.0" encoding="utf-8"?>
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
<connectionstrings xdt:transform="Replace">
<add name="TestContext" connectionstring="Data Source=REALEXISTINGSERVER;Initial Catalog=TestDb; Integrated Security=true" providername="System.Data.SqlClient"/>
</connectionstrings>
</configuration>
However when I created the build definition and added the configuration =Build I get this error
Error: 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: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) ---> System.ComponentModel.Win32Exception: The network path was not found
Which means is taking the app.config file and not the transformation
You can use SetAttributes
<connectionStrings>
<add name="TestContext" connectionString="Data Source=REALEXISTINGSERVER;Initial Catalog=TestDb; Integrated Security=true" providername="System.Data.SqlClient"
xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/>
</connectionStrings>
please refer to
How do I use Web.Config transform on my connection strings?

I am referencing 2 databases in ASP.NET using Entity Framework.
In my web.config file, I can see the connection strings for the 2 databases:
<connectionStrings>
<add name="RContext"
connectionString="metadata=res://*/Models.RModel.csdl|res://*/Models.RModel.ssdl|res://*/Models.RModel.msl;provider=System.Data.SqlClient;provider connection string="data source=localhost\SQLEXPRESS;initial catalog=RStreamline;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework""
providerName="System.Data.EntityClient" />
<add name="CEntities"
connectionString="metadata=res://*/Models.CModel.csdl|res://*/Models.CModel.ssdl|res://*/Models.CModel.msl;provider=System.Data.SqlClient;provider connection string="data source=localhost\SQLEXPRESS;initial catalog=RStreamline;integrated security=True;MultipleActiveResultSets=True;App=EntityFramework""
providerName="System.Data.EntityClient" />
</connectionStrings>
Can I somehow implement alternate connection strings where the datasource refers to the prod server for the release?
This is typically handled with web.config transforms.
In your project you would have:
web.config
web.Release.config
For example in your web.Release.config transform you would have something like this:
<?xml version="1.0"?>
<configuration xmlns:xdt="https://schemas.microsoft.com/XML-Document-Transform">
<connectionStrings>
<add name="RContext"
connectionString="RContext-Prod-Connection-String"
xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/>
<add name="CEntities"
connectionString="CEntities-Prod-Connection-String"
xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/>
</connectionStrings>
</configuration>
You'll notice the xdt:Transform="SetAttributes" xdt:Locator="Match(name)" bit, which says, in the main web.config find the connectionString by name and replace its attributes with the ones defined here.
This will automatically happen when you publish the application.
I've created a .net service that work with a database declared in web.config file. Now the project evolved and i need to query more than 1 database, how can i do this in web.config and then specify the database i want to query in the c# files?.
Here's how the current database is specified:
<connectionStrings>
<add name="stringName" connectionString="Data Source=XXXXXXXXX;Initial Catalog=DBName;Persist Security Info=True;User ID=UsrID;Password=bazinga;Application Name=AppName;Connect Timeout=20" providerName="System.Data.SqlClient"/>
</connectionStrings>
Thanks!
You just add another item to the connectionStrings section with a different name specification.
How your program calls the database is another story and I do not have the section of code which is defining the existing one. You would just need to find that and use the same method, just adding another variable to identify it.
<connectionStrings>
<add name="stringName" connectionString="Data Source=XXXXXXXXX;Initial Catalog=DBName;Persist Security Info=True;User ID=UsrID;Password=bazinga;Application Name=AppName;Connect Timeout=20" providerName="System.Data.SqlClient"/>
<add name="stringName2" connectionString="Data Source=XXXXXXXXX;Initial Catalog=DBName;Persist Security Info=True;User ID=UsrID;Password=bazinga;Application Name=AppName;Connect Timeout=20" providerName="System.Data.SqlClient"/>
</connectionStrings>
I have an ASP.net web application hosted in IIS. This application use SQL Server.
I removed connection string in web.config. But when I start the application, it is still connected to it.
The connection string was nowhere explicitly stated.
how does it work?
By default the machine.config located in C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config\machine.config have the following connection string configured.
<connectionStrings>
<add name="LocalSqlServer" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient"/>
</connectionStrings>
By leaving the <connectionStrings> section of your web.config empty you are not removing the default connectionstring. To ensure that you have no configured connection string you should use a <clear /> element in your web.config file.
<connectionStrings>
<clear />
</connectionStrings>
I have created an mvc 4 database application on "PC1". I just have chosen by right click "Database SQL Server" and created Entity Framework with Database First approach. It works okay at "PC1". But when I copied my project to another PC, then the project failed.
I do not have an SQL Server at the PC. I just copied the mvc 4 project with local database.
The error is: "...(provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)"
I suppose that I should rewrite connection string. I've done this steps:
http://msdn.microsoft.com/en-us/library/hh873188.aspx
And I have tried to change a connection string from:
<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=aspnet-TestApplication-20140918110411;Integrated Security=SSPI" providerName="System.Data.SqlClient" />
<add name="CustomerDatabaseEntities" connectionString="metadata=res://*/UserModel.csdl|res://*/UserModel.ssdl|res://*/UserModel.msl;provider=System.Data.SqlClient;provider connection string="data source=.\SQLEXPRESS;attachdbfilename=|DataDirectory|\CustomerDatabase.mdf;integrated security=True;user instance=True;multipleactiveresultsets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />
<add name="CustomerDatabaseEntities" connectionString="metadata=res://*/UserModel.csdl|res://*/UserModel.ssdl|res://*/UserModel.msl;provider=System.Data.SqlClient;provider connection string="data source=.\SQLEXPRESS;attachdbfilename=|DataDirectory|\CustomerDatabase.mdf;integrated security=True;user instance=True;multipleactiveresultsets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />
</connectionStrings>
To:
I have added name of PC(TomPC) to connection string:
<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source=.TomPC\SQLEXPRESS;Initial Catalog=aspnet-TestApplication-20140918110411;Integrated Security=SSPI" providerName="System.Data.SqlClient" />
<add name="CustomerDatabaseEntities" connectionString="metadata=res://*/UserModel.csdl|res://*/UserModel.ssdl|res://*/UserModel.msl;provider=System.Data.SqlClient;provider connection string="data source=.TomPC\SQLEXPRESS;attachdbfilename=|DataDirectory|\CustomerDatabase.mdf;integrated security=True;user instance=True;multipleactiveresultsets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />
<add name="CustomerDatabaseEntities" connectionString="metadata=res://*/UserModel.csdl|res://*/UserModel.ssdl|res://*/UserModel.msl;provider=System.Data.SqlClient;provider connection string="data source=.TomPC\SQLEXPRESS;attachdbfilename=|DataDirectory|\CustomerDatabase.mdf;integrated security=True;user instance=True;multipleactiveresultsets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />
</connectionStrings>
However, it fails with the same error.
I would greatly appreciate any help!
You will also need to ensure that TCP/IP is enabled in SQL Server config on TomPC, and also open up port 1433 (the default port, but it might be different, e.g. if there's more than one instance of SQL running on that PC).
Data Source=.\SQLEXPRESS
The . means "localhost" or 127.0.0.1
So adding the . means localhost\SQLEXPRESS or 127.0.0.1\SQLEXPRESS
You need to change it to:
Data Source=TomPC\SQLEXPRESS
I've found an answer. The application could not connect as connection string should be modified as LocalDB:
<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source=(LocalDB)\v11.0;Initial Catalog=aspnet-TestApplication-20140918110411;Integrated Security=SSPI" providerName="System.Data.SqlClient" />
<add name="CustomerDatabaseEntities" connectionString="metadata=res://*/UserModel.csdl|res://*/UserModel.ssdl|res://*/UserModel.msl;provider=System.Data.SqlClient;provider connection string="data source=(LocalDB)\v11.0;attachdbfilename=|DataDirectory|\CustomerDatabase.mdf;integrated security=True;multipleactiveresultsets=True;App=EntityFramework"" providerName="System.Data.EntityClient" />
</connectionStrings>

I am have a register page on my website built in VS2010 and when I fill the form in a click register I am getting the following error. Help would be appreciated.
System.Exception was unhandled by user code
Message=Insert Error:Directory lookup for the file "C:\Users\myname\Documents\myname\Project\App_Data\SJDatabase.mdf" failed with the operating system error 5(error not found).
Cannot attach the file 'C:\Users\myname\Documents\myname\Project\App_Data\SJDatabase.mdf' as database 'SJDatabase'.
connection string:
<connectionStrings>
<add name="ApplicationServices" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|\aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient"/>
<add name="MyConsString" connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|SJDatabase.mdf;
Initial Catalog=SJDatabase;
Integrated Security=SSPI;"
providerName="System.Data.SqlClient" />
</connectionStrings>
I think you are missing a backslash on |DataDirectory|\SJDatabase.mdf
also, you have Integrated Security=SSPI twice and I dont think you need the AttachDBFileName part
try something more simple like this:
"data source=ServerName;Initial Catalog=SJDatabase;Integrated Security=SSPI" providerName="System.Data.SqlClient"
