I am using Visual Studio 2015 professional. When I tried to add Service-based Database to my project I got this error.
Connections to SQL Server database files (.mdf) require LocalDB or SQL Server Express to be installed and running on the local computer. You may need to modify the setup and ensure Microsoft SQL Server Data Tools is selected and install the current version at: http://go.microsoft.com/fwlink/?Linkid=125883
I also have Microsoft SQL Sever 2014 installed on my computer. really need help.
Just in case it helps others, I recently received this error in Visual Studio. The error states to go to http://go.microsoft.com/fwlink/?Linkid=125883 . When going to this URL, it now redirects to https://www.microsoft.com/en-us/server-cloud/products/sql-server/ . The new URL do not seems to have an obvious instructions on how to get Microsoft SQL Server Data Tools. Here is what worked for me.
After doing this, just to play it safe, I restarted Visual Studio. This might not be necessary. I then did the following in Visual Studio.
The error should not appear, and in Solution Explorer should now be a file named database1.mdf.
Just do this. On Visual Studio, go to Tools > Options > Database Tools > Data Connections. Here clear the "SQL Server Instance Name (blank for default)" option and write SQLEXPRESS
The error message is quite clear. You need to have either LocalDB or SQL Server Express installed and running on the local computer, and you apparently don't.
Do as the error message instructs, go to the link provided in that error message, select Microsoft SQL Server Data Tools, and install the latest version.
