I try to add Service based databse in VS2020.

i got this Error Message:

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

What I have tried:

Add--->Newitem from VS2022---> Data---->select service based Database. add. i got bove Error

I did a fresh install of SQL Server Express 2018
I verified 'LocalDB' was included in the installation.
Tried to connect to a known working .MDF database file in Visual Studio 2022,
but always get the error message.

You don't connect to the file; you connect to the SQL Server instance.

The error message is very clear. In first part need to check the point-1
and for second error part you need to very the point-2.
1. LocalDB or SQL Server Express installed and running on the local computer
2. SSDT installed. To check follow [Tools > Extensions and Updates -> Installed > Updates]
If update not works then go the link https://msdn.microsoft.com/en-us/mt186501[^] download it and install into your system.
Happy Coding!!
