I'm getting an exception when attempting to open a SQL Server connection from a class library when the same connection / connection string code works fine within the main application.
The following code opens a connection from the main application (ASP.NET Framework application targeting .NET Framework 4.8):
const string connStr = "Data Source=(local);Initial Catalog=DatabaseTest1;Integrated Security=True;MultipleActiveResultSets=True";
var connection = new SqlConnection(connStr);
connection.Open();
connection.Close();
If I then (or before) try to call exactly the same code from a class library (net48 and net6.0) I get a 20 second pause on the Open() statement, during which the output window reports around 24 of the following:
Exception thrown: 'Microsoft.Data.SqlClient.SqlException' in Microsoft.Data.SqlClient.dll
eventually throwing the following exception (no inner exception):
[Microsoft.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: HTTP Provider, error: 0 - )
I'm suspecting some kind of conflict between .NET Framework versions and/or [System/Microsoft].Data.SqlClientbut I can't get to the bottom of it.
The class library uses these nuget packages:
Dapper 2.0.123 (latest)
Microsoft.Data.SqlClient 5.0.1 (latest)
Ninject 3.3.6 (latest)
The main ASP.NET Framework application has lots more but those that I think are relevant are:
EntityFramework 6.4.4 (latest)
Ninject 3.3.6 (latest)
It also has a reference (non nuget) to System.Data 4.0.0.0 which is where it's getting SqlConnection class from. Could this be the cause? Some kind of conflict here?
The class library code has been working until recently has it's been in production for a couple of years or more.
Any advise would be welcome. Thanks.
UPDATE
When I add ;TrustServerCertificate=True to the connection string, I see the following in the output window during the Open() operation and the whole application bombs out!
Exception thrown: 'System.AccessViolationException' in Microsoft.Data.SqlClient.dll
I've created a test .NET Framework console app and included the class library. The database connection works but only after I [a] changed both library and console app from "Any CPU" to "x86" and [b] manually added the Microsoft.Data.SqlClient.SNI.x64.dll/pdb files to the bin folder. ("Any CPU" looked for the equally absent Microsoft.Data.SqlClient.SNI.x86.dll file). My main application still failing after changing all assemblies from "Any CPU" to "x64".
UPDATE 2 (2023-01-19)
Logging the exception shows below, but the database name and server name are correct. The connection string is:
Data Source=(local);Initial Catalog=ActivbaseTest1;Integrated Security=True;MultipleActiveResultSets=True;TrustServerCertificate=True;Encrypt=false
The stack trace shows:
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: HTTP Provider, error: 0 - )

Could this be an issue with what user the connection is using? The main part of the app (using EF) connects with the site's application pool user account and works but I don't know how to check or how to set Dapper to to use the same?
Is the connection string exactly the same to your application and the test console app (2.) that you created?
I would suggest to add "Trusted_Connection=True;" to your connection string since you are connecting to the database without user and password, i.e. using the windows auth.

I had same error, I later figured out that I was using a forward slash (/) instead of backslash (\) slash in my connection string.
This was what I was using-:
Server=(localdb)//mssqllocaldb;
While this was the correct connection string:
Server=(localdb)\\mssqllocaldb;
There could be several issues causing your error:
1) Make sure your server name is correct, e.g., no typo on the name.
2) Make sure your instance name is correct and there is actually such an instance on your target machine. [Update: Some application converts \ to . If you are not sure about your application, please try both ServerInstance and Server\Instance in your connection string]
3) Make sure the server machine is reachable, e.g, DNS can be resolve correctly, you are able to ping the server (not always true). Simply open Command Prompt and type "-ping yourservername" if it is a named instance or "-ping yourserverIP" if it is an unnamed instance.
4) Make sure SQL Browser service is running on the server.
5) If firewall is enabled on the server, you need to put sqlbrowser.exe and/or UDP port 1434 into exception.
I had the same issue with an application of mine and it was resolved by 4), enabling the SQL Browsing service on the server.

In my case it was intermmitent error, on and off. It was caused by DB server having IP conflict. Hope this will help somebody.
*Localhost Sql server
*Database name is sample
*connectionString name is SampleConnectinString
Just check for connection string, your error will go
<connectionStrings>
<add name="SampleConnectinString" connectionString="Data Source=.\SQLEXPRESS; Integrated Security=true;Initial Catalog= sample;" providerName="System.Data.SqlClient" />
</connectionStrings>
*using connectionstring in ado.net
string cs = ConfigurationManager.ConnectionStrings["SampleConnectinString"].ConnectionString;SqlConnection con = new SqlConnection(cs);
the connection string might be the problem.check once whether you were able to login in sql server in your pc with the connection mentioned in config file.
FYI:IIf yusing go daddy as host remove the name after colon in host.
eg:host=198.71.225.113:1433
use only "data source=198.71.225.113" ignore ":1433"
Context
Currently I am creating an Extract, Transform and Load (ETL) application written in C# with .NET Core. The target of the ETL application is a database that is accessed through Entity Framework Core 2.1.0 and later 2.1.1. A database first approach is used, since the schema's are fixed. Microsoft offers the following guide to approach this situation. The guide states that the CLI command Scaffold-DbContext in the Package Manager Console can be used to generate the DbContext and the corresponding entity models.
Earlier in this project I have successfully used this CLI command. However the naming of the models did not correspond directly to the table and column names. The newer versions of this CLI Tooling offers a option -UseDatabaseNames, so I therefore opted to rerun this command in order to generate some updated models. Additionally, regenerating the DbContext is something I am planning to do more often in the future.
The Problem
Unfortunately running the Scaffold-DbContext command now returns the following error: Instance failure.. The verbose option gives some more insight into what is going wrong, but I am unclear as to what exactly is going wrong and how to resolve it.

Instance failure.
As stated before I am unclear what exactly is going wrong. My google searches have not resulted in any relevant information. Additionally I have tried updating the SDK, tools and other references. And I tried deleting the DbContext and models. Any help would be greatly appreciated!
I think you need to change your instance name.
For example :
Scaffold-DbContext "Server=PC\SQLEXPRESS;Database=***;User
ID=sa;Password=****" Microsoft.EntityFrameworkCore.SqlServer
-OutputDir model
So your instance in this case is : PC\\SQLEXPRESS.
This instance should be like this : .\SQLEXPRESS
This is indeed an instance error. I copied the connection string from one of my classes. My SQL server instance is PC\Expresss, but my connection string was PC\\Express, just removed a back slash.
Yea this is usually a matter of mis-spelling the instance name in your scaffold-dbcontext command on the PM Console..
You can use this little TSQL to find out the exact spelling of your SQL Server instance: SELECT ##SERVERNAME
I have a .NET 4.5 Forms application that works great locally. Does not require any authentication and I can use all pages. However, I am able to register user, log in and log out without any problems.
On godaddy, I can get to an HTML page I put on godaddy so everything is setup fine. But when I try to go to Default.aspx, I get a log in error even though nothing is requiring authentication locally. When I try to register a user, I get this error below.
One thing I noticed is that my application is 4.5 and this error shows 4.0 at the bottom. Now on godaddy, they just say you are using 4.0/4.5. There is no separation between them. I have talked to godaddy few times but they say they have very little technical help for custom sites like this and I have to resolve these. But if the .NET version is the problem, I will convert my projects or recreate them in 4.0.

Version Information: Microsoft .NET Framework Version:4.0.30319;
ASP.NET Version:4.0.30319.18055
I have a .NET 4.5 Forms application that works great locally. Does not
require any authentication and I can use all pages
If you run the application locally, Visual Studio uses SQL Express for development. As the result, it is working without even you notice it. Normally, the database is created inside App_Data folder.
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.
However, when you deploy the application (to GoDaddy), you need to explicitly provide the connection in web.config to connect to actual SQL Server.
According to the above error message, you did not provide the correct connection string in web.config.
ASP.NET MVC 4 website, SQL Server 2012.
When I upload all files to Windows Server 2008 R2, source, web config etc, the app works fine.
When I use 'Web Deploy' - which only uploads 'required files', ie strips out source files, web.config etc - it comes up with 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)

As there is no web.config on the server now (I assume it has been compiled into a .dll) - and the error message doesn't tell me what it is trying to connect as - how on earth can I debug this? How can I find out what connection string it is trying to use?
There is no transform in web.release.config to change the connection string.
Any ideas how to debug - and what might be causing this?
Thanks.
Web.config is not compiled into the dll of your website. If your connection string is stored in the web.config, make sure the file is on the server when running the website. Do either of the following:
Include web.config in deployment by following the steps in this previous answer.
Manually copy web.config to your server and change the settings there. This will prevent overriding the settings when deploying.
For a production website, the second option is probably the best.
try saving connection string in web.config file. Then run it.

I have the same problem with connecting to remote sql server from vs2012
This problem may occur if one or more of the following conditions is true:
SQL Server is not configured to accept remote connections.
The necessary protocols for SQL Server are not enabled on either the SQL Server computer or the SQL Server client computer that is running BizTalk Server.
Following these steps may resolve this problem:
The SQL Server Surface Area Configuration tool is not available on SQL Server 2008. To enable remote connections for SQL Server on a SQL Server 2008 computer follow the instructions in the SQL Server 2008 online help.
Use the SQL Server Configuration Manager tool to enable the TCP/IP and/or the Named Pipes protocols on the SQL Server computer.
Click Start, point to All Programs, and click SQL Server Configuration Manager.
Click to expand SQL Server Network Configuration and then click Protocols for MSSQLSERVER.
Right-click the TCP/IP protocol and then click Enable.
Right-click the Named Pipes protocol and then click Enable.
Close the SQL Server Configuration Manager tool.
Use the SQL Server Configuration Manager tool to enable the TCP/IP and/or the Named Pipes protocols on the SQL Server client computer that is running BizTalk Server.
Click Start, point to All Programs, and click SQL Server Configuration Manager.
Click to expand SQL Server Network Configuration and then click ClientProtocols.
Right-click the TCP/IP protocol and then click Enable.
Right-click the Named Pipes protocol and then click Enable.
Close the SQL Server Configuration Manager tool.
Note: Ensure that at least one of the protocols on the SQL Server client computer that is running BizTalk Server matches the protocols enabled on the SQL Server computer.
