The exception says that there is a network related problem, or that the SQL server does not allow remote access, none of those are true.
Can it be that I'm trying to connect a MySQL server, and not MS SQL?
Thanks
It is because the System.Data.SqlClient namespace is designed for Microsoft SQL Server, to connect to MySQL you will need to download and reference the MySQL .NET Connector http://dev.mysql.com/downloads/connector/net/. You will then use the System.Data.MySqlClient namespace. Hope this helps.

I'm trying to use Altova DatabaseSpy to connect to my remote MySQL server as a data source. I'm getting an error though
Here are the menus I'm going through:
I'm using the same port/user/password as when I connect with Django, but it's not working. I also tried using ApexSQL and can't get that to connect either.
You need to use the ODBC driver for MySQL, not Microsoft SQL Server

Is there any way to connect SQL Server 2008 Reporting Services to a Sybase SQL Anywhere database (ASA or ASE)? Maybe using ODBC...
If so, have you done it? Kindly share experiences and any notable considerations.
Our environment is x64 SQL RS but needs to connect x86 SQL Anywhere 9.0. 64bit SQL doesn't recognize 32bit ODBC SQL Anywhere. We resolved the issue by installing a x86 SQL Server 2008 R2 express, setup a System ODBC for SQL anywhere and linked server to SQL Anywhere on SQL instance.
Check "Allow inprocess" in the the linked servers->Provider->ASAProv.90. Restart SQL Service
Linked server -> Server Options: Set RPC and RPC Out both to True.
I have had success setting up the Data Source Type (DPE) as OLEDB and using the ASA 9.0 OLEDB provider. The connection string editor in VS2008 does not allow me to create a connection string that works, so I just type in the entire connection string as follows:
Provider=ASAProv;Eng=[ASAInstanceName];Dbn=[ASADatabase];Uid=[ASAUser];Pwd=[ASAPwd];Links=tcpip(host=[servername])
Replace the the portions with square brackets with the values that are appropriate for your installation. The square brackets should NOT be in your final connection string and quotes are not need either. The links statement at the end is probabaly not necessary if the database is on your local machine. Even though I included the database username and password, it didn't seem to be used. I also had to set them in the DataSource Credentials. When deployed to SSRS, I also set them in the DataSource to be saved on the server.
I've noticed that performance is VERY slow when previewing the report in local mode in VS 2008. Instead, I have started deploying my report everytime I want to "preview" it so I can look at it on the SSRS server through a browser. Performance is much better that way.
I am looking for a BETTER solution than what I've described as I've quickly found that multiple-value parameters are not supported with this type of connection to ASA. If you find a better solution, perhaps using the ASA ADO.NET Provider, please post. From what I've found though, there is no DPE that exists for ASA.
I want to use MYSQL database for accesssing the data in a mvc application.
The connection string that i am using in web.config is:
Then I have prepared a model,controller,view for accessing and displaying the data.
I am using LINQ o get the data from database but getting the exception:" 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)"
I have also installed the MYSQL connector.
Please provide me the solution to access the data using MYSQL and LINQ in MVC application
Thanks in advance.
Deleting my previous answer...I read your question as LINQPad, no idea why.
To be short, get a third party provider, I can't speak for others, but devart's dotConnect for Oracle has worked very well for us: Here's their MySQL version.
You could use NHibernate and Linq-to-Nhibernate and then you are not database tied.
NHibernate Files
http://sourceforge.net/projects/nhibernate/files/
But this I guess is dependent on how much time you have to develop!
You can't use LINQ to SQL. You should use entity framework.
Linq to SQL is only for MS Sql.
Use EF to work with any other DB, and then you can use LINQ to EF.
Linq to SQL is obsolete

LinQ to Sql is used to Connect the MsSql to LinQ.We need third party softwares to Connect LinQ with MySql.
I Can Connect LinQ and Mysql with the help of DbLinq
