PC running slow?
Recently, some of our readers encountered a well-known error code: Named Pipes Provider Error 40 Visual Studio. This problem occurs for several reasons. We will discuss this below.
TL;DR; Your instance of SQL Server dynamically uses non-working memory areas. Force SQL Server to use static port number 1433.
Full details. First, a particular problem is more likely if only a combination of default instances and selected or named instances was previously obtained (as in my case).
The key to every concept. The instance of Microsoft SQL Server installed on the large computer uses a different port, so it listens for incoming connection requests. The SQL Server condition defaults to field #1433. If you install identified instances, they will start creating dynamic ports that exist at a specific time when the Windows service corresponding to the specified SQL Server instance starts.
My code was unable (with error rule 40) to connect only to the named instance of SQL Server I had in my virtual machine. You can try the following possible solutions:
Can’t open a connection to SQL Server Named Pipes?
Check certain protocols TCP/IP and Named Pipes as the port. Open SQL Server Configuration Manager and check the SQL Server Network Configuration logs. You must enable named pipes and TCP/IP. For each TCP/IP protocol, right-click and select Properties to also check the TCP/IP mail port.
Decision #1. Client code, tryStopping an instance of SQL Server requires permission from the SQL Server Browser service to know the port number of your backend whose named instance is listening for incoming connections. Make sure the Internet SQL service is running on your computer.
Solution #2: Check the port number (highlighted in yellow) that your named instance of SQL Server is using as a handler in the SQL Server configuration by taking the following snapshot:
Use this connector number explicitly in the connection archipelago or with
as shown below.
How do you check Named Pipes TCP is enabled?
Stop the entire agent.Open SQL Server Configuration Manager >> SQL Server Network Configuration >> Protocols for MSSQLSERVER >> Look at “TCP/IP” on the right and select “Enable” >> Right click on “Named Pipes” and select “Enable”.
sqlcmd -ise mymachinename,11380 -i deleteDB.sql -o SQLDelete.txt
Solution #3: Apply a named instance and use port #1433, which is actually used by the default instance. Keep in mind that some of these will only work if you really don’t have a standard sql server as an example on your machine that is behind a sql server instance that is already using port #1433. Same port number can be used by more than just two different Windows services.
TCP Dynamic Ports field is empty and the
TCP Port field is 1433.
Change the dock number in the connection string to:
is displayed sqlcmd -s mymachinenameinstanceName -i deleteDB.sql -o SQLDelete.txt
sqlcmd -s mymachinename,1433 -i deleteDB.sql -o SQLDelete.txt
How do I fix Provider Named Pipes Provider error 40 could not open a connection to SQL Server?
Make sure the SQL Server service is running.For the labeled instance, ensure that the SQL Server Visitor Service is running.Make sure SQL Server is configured to allow private connections.Examine the SQL Server error log for messages confirming that SQL is listening on the expected network interfaces, not to mention ports.
Note. Any changes to the relevant TCP/IP settings require a Windows restart.
Interestingly, after fixing the bug, I went back to setting up dynamic relocation to reproduce the bug in the same way when it didn’t exist. I really don’t know why.

In this blog, I received advice on solving my personal problem.
How do I fix named pipe Error 40?
SQL Server must be operational but running.Enable TCP/IP in the SQL Server configuration.Open a port in Windows Firewall.Enable remote connection.Enable the SQL Server Browser service.popsgive the sqlbrowser.exe file associated with the exception in the firewall.Recreate the alias.
System.Data.SqlClient.SqlException: “There was a network and/or instance-specific error while connecting to SQL Server. Server not found or unavailable. Make sure the incident name is correct and SQL Server is configured to allow connections to the controller. (Supplier: PostaNamed pipe manager, error: 40 – Could not open a specific SQL connection to the server) ‘
This indicates that the web server is allowing the remote connection and instance. I also checked the connection to this, everything is generally fine. Can anyone tell me how to resolve this issue.

Really: 1 problem is not solved in your guide, the NuGet package from Universal Windows is indeed missing. 🙂 Even adding physical references to the MySql DLL does not result in performance improvement, for UWP the way is to put a NuGet package manager (or manually in Windows VS choice) in MySql.Data (or whatever package people using MySql have) run and build . to rule.
Then all functions work o/ .
