It's not Visual studio that's the problem: it's the version of SQL that teh DB file was created with.
Open SSMS, and open a new query window.
Enter the query:

SQL

DBCC CHECKPRIMARYFILE('PathToDataBaseFile',2)

And execute it. For example:

SQL

DBCC CHECKPRIMARYFILE('D:\Database Backups\SM_XRVCB.mdf',2)

The response you get includes the version number:

property           value
Database name      SM_XRVCB
Database version   706
Collation          53256

In this case, the file was created with V706, which is SQL Server 2012:

SQL Server Version	Internal Database Version
SQL Server 2016         852
SQL Server 2014         782
SQL Server 2012         706
SQL Server 2008 R2      660/661
SQL Server 2008         655
SQL Server 2005         611/612
SQL Server 2000         539
SQL Server 7            515

So if your error is saying V782, then it's SQL Server 2014, and the version number of the DB file cannot be higher than 782.
Then look at the instance you are connecting to (look at the connection string your code is using) and find out what version of SQL that server is (that's simple, SELECT @@VERSION will do it!). You need to point that connection string at the right server: I.e. 2016 or later in order to open the file.
