Firstly, Visual Studio 2013 connects to database and retreive tables normaly.
I added more table to database and edit relationship. After that I update data source in Project Explorer tree but it's failed. Even I tested the connection It's ok. But VS 2013 cannot retreive data objects - Message Box shows "Retreiving database object..." in very long time without reason. Can you show me how to fix it?
I found the way to fix this error. Just only find and kill all of process are using database

I am trying to connect to our Oracle database using Visual Studio (VS) 2017 (i am not able to upgrade to the latest version due to company policy). So far, I have downloaded ODTwithODAC183 from this site: https://www.oracle.com/database/technologies/dotnet-odacdev-downloads.html
I have done the installation properly , after the installation, I opened VS, and clicked on Tools -> Connect to Database and chose Oracle Database
After pressing OK, I got this screen below and filled it up accordingly:
Next I clicked on test connection, and I received a message saying that the connection is successfully established, however, on the second screenshot, if you look under Data Connection at the left side, under tables -> Relational tables, it is completely empty and none of the tables from the database have loaded.
I was wondering if anyone could please help me figure out how I can view the tables from an Oracle database using Visual Studio 2017.
thank you!
Last year, I used VS2010 to develop a Winforms application. Now, I changed to VS2013 and I faced some problems.
I couldn't find a way to manage SQL Server Compact Edition database files (.sdf) in VS2013. Although I have installed an add-in from this website
But I can only see the top 200 rows of data in the .sdf, I can't open connection in order to add more data with code.
Is there any solution for me ?
Go to Options in the addin, and you change 200 to any number
Could you clarify what you mean by: "cant open connection in order to add more data with code" ?
I have connected with the database successfully by using wizard in server explorer. but the data source is showing nothing. i have googled and search on msdn help. but not get help.
I want to add data source. but add new data source option is disabled for me.
I am using windows form application...
I want ask that am i doing right. could you please tell me how can i get rid of not showing thing.
PLEASE HELP!!!
The Server Explorer of Visual Studio 2010 and the Datasource of your application are completely different. Check the following links to see how you can connect your Windows Form Application with Sql-Server database:
Walkthrough: Connecting to Data in a SQL Server Express Database (Windows Forms)
Connecting to a Database with Visual Studio Tools
When i trying to create. Mdf file in App_Data folder in visual studio 2010 I see this message.
"Failed to generate user instance of SQL Server due to an error when starting the process for an instance of the user. The connection will be closed."
I can to create the database other ways. (In visual studio -> Tools-> Connect to the database and SQL Manager). SQL Server is installed automatically studio.
How can I solve this problem?
What am I doing wrong?
This is not exactly an answer to your question, however I think it is very important you read this link first before attempting any further resolutions to your problem.
I've created a database in visual studio 2010 in the following way: Data->Add new datasource->Database->Entity Data Model.
Now, in my wpf app I can load and save data successfully, when closing the
app and opening again the data will still be there, but as soon as I try
retrieve the table data in Visual Studio's Database explorer it returns
an empty table, and running the application after that also returns no data.
It is as if using database explore to query data clears it.
Any help would be greatly appreciated.
