My SQL Server Object Explorer is not showing any databases:
I also get an error A network-related or instance-specific error occurred while establishing a connection to SQL Server. .... When I run the website, the error being shown is The system cannot find the file specified. Furthermore, SQL Server is missing from Services:
(It was installed together with Visual Studio and was never used separately)
Yesterday, everything worked like charm; I had multiple databases with tables and was able to access the data. Today, the same project can't even start, no db's either. What's wrong with Visual Studio here? Thanks
I've had the same problem before. Took me a while to figure it out. What you need to do is go here: https://www.microsoft.com/en-us/download/details.aspx?id=42299
In my case, i'm using SQL Server 2014 Management Studio. You must find the one that suits the version of SQL studio that you're using (2008, 2012, 2014).
Click the big download button and now, it is very important that you choose the proper version. Check:
Express 32BIT\SQLEXPR_x86_ENU.exe if you're running on a 32-bit PC, or
Express 64BIT\SQLEXPR_x64_ENU.exe if you're running on a 64-bit PC
It is very important that you install Express version.
Next, once you install that, you should be able to see the SQL Server (MSSQLSERVER) in your services.msc, along with few other SQL services installed.
Open Visual Studio 2015 and in SQL Server Object Explorer window right click on SQL Server and choose Add SQL Server... option. It should prompt you to connet to the server from SQL Server Management Studio.
If you kept everything by default during the installation, just type . (dot) for the Server name and click connect. Now it should load the database.
It turns out that Visual Studio does not come with MS SQL Server in the default installation. It is necessary to install SQL Server Data Tools from the MS website manually. VS custom installation also allows to do that, but you will need an installer. Just make sure to select SSDT in the custom installation components menu. Additionally, I also ran an update from VS itself that allowed me to install SQL Server 2008, 14, and 16. I am finally able to access DB in VS!

I want to run an ASP.NET project on VS 19 but whenever I open it, it shows an error dialog box that “this project requires SQL Server 2012 which is not installed on this computer” - but SQL Server 2012 is installed with all services running.
And database cannot be created showing an error
A network related or instance specific error
I guess Visual Studio 19 is somehow not recognising SQL Server 2012 services and I can't figure out how to fix it.
Also tried to disable firewall and enable all TCP/UDP Connections but of no use, kindly help as it's very frustrating.
I'm sorry for using sloppy naming schemes as i'm new to Stack Overflow.
Installing SQL Express LocalDB helped me solve the problem, i thought i had it installed from the SQL Express tools available Microsoft SQL Download, but the SQL Express LocalDB was missing. It sounds stupid, but it is what it is, hope it helps anyone else.
I have been learning ASP.NET and building a little customer portal. I used the built in CreateUserWizard. I wanted to look inside the ASPNETDB.MDF file to see how it was storing the users and maybe add some rows of my own. I opened the file in SQL Server Management Studio and viewed the file. I closed it with out saving.
Now when I try to run the program I get this new error:
The database 'C:\PROJECTS\PORTAL\PORTAL\APP_DATA\ASPNETDB.MDF' cannot be opened because it is version 706. This server supports version 662 and earlier. A downgrade path is not supported.
So I assume opening the project in SQL Server it upgraded the version to 706, How can I either delete this database and create a new one or change the version of the database to an support version.
Thanks
The following blog entry will help you
http://conceptdev.blogspot.com/2009/04/mdf-cannot-be-opened-because-it-is.html
As soon as you attached it to SQL Server 2012, the database was upgraded to version 706. As the error message suggests, there is no way to downgrade the file back to version 662 (SQL Server 2008 R2).
You can run the script found in your Visual Studio folder -
[drive:]\%windir%\Microsoft.NET\Framework\version\asp_regsql.
It'll display a UI for you to select the server to install a new copy on. Here's a MSDN article about it.
I am getting this error and I have SQL Server 2012 installed anyone know what's wrong? I am trying to attach a database file into my Visual Studio 2010.
The database 'X' cannot be opened because it is version 661. This
server supports version 655 and earlier. A downgrade path is not
supported.
Could not open new database 'X'. CREATE DATABASE is aborted.
An attempt to attach an auto-named database for file X failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.
The database file was created and/or attached on a SQL Server instance that was of a newer version than the one you have. If you bring your local instance up-to-date to a newer build, then you should be okay.
More specifically - version 661 is SQL Server 2008 R2. The instance you are attaching (651) to is SQL Server 2008 RTM or SP1. Be sure it is using SQL Server 2012 instance instead of perhaps a local SQL Express instance.

Turns out the problem is with regard to an Express Edition. I cannot use the full version because the mdf file I'm binding requires user instance which is only supported by Express Editions. I downloaded the SQL 2012 Express from this https://www.microsoft.com/betaexperience/pd/SQLEXPWT/enus/default.aspx which allows for LocalDB and all the problems go away.
I want to create a database(.mdf) within my website. When i try to add sql server database by:
right clicking the project->add new item->Sql Server Database. I get the following error:
I have sql server 2008 installed on my machine and i have been using it to connect to different databases of sql server by going in the "Server Explorer" section of Visual Studio, as shown below:
But when i try to create a database with my website, i am having problems. I am using Visual Studio 2010.
Please help?
I am following the learning ASP.NET 3.5 by O'REILLY to write some ASP.NET 3.5 code using Visual Studio 2008 SP1. I have gotten to the point to where I need to Configure a Data Source using the SqlDataSource control. I chose Microsoft SQL Server (SqlClient) even though I have SQL Server Express 2005 - This seems like the only logical choice.
I get to the Add Connection window and successfully add a Server name and I use the Select or enter a database name of AdventureWorks. When I click on Test Connection I get the Test Connection Succeeded message box.
Unfortunately, when I click OK I get an error message of the following:
Could not load file or assembly 'Microsoft.SqlServer.Management.Sdk.Sfc, Version=10.0.0.0, Culture=neutral,
PublicKey Token=89845dcd8080cc91' or one of its dependecies. The system cannot find
the file specified.
At his point I am at a loss and everywhere I look and find something similar to my issue it involves other versions of either Visual Studio or SQL Server.
I'd really appreciate any help on this!
You may investigate this recipe.
You may need to reinstall your copy of SQL 2005 Express. But sure to install all of the client-side developer packages in the installer.
I had the exact same issue.
Following the suggestions in this thread , I went to the "Microsoft SQL Server 2008 Feature Pack, August 2008 " - and downloaded (and installed) the "Microsoft SQL Server 2005 Backward Compatibility Components ". This did not help.
Then I also downloaded and installed the following components: SharedManagementObjects.msi, sqlncli.msi, SQLSysClrTypes.msi.
And now it works for me.
I'm using SQL Server 2008 Express and Visual Web Developer 2008 Express Edition.
