Queries run slow after updating database from SQL 2008 r2 to 2014

Question

I've changed my database edition from 2008 r2 SQL server express to 2014 enterprise edition. The point is, queries run like 3 times slower than the old server. I'm testing on the same data and I've already tried the following: SQL Server 2014 upgraded - queries very slow

Nothing have changed even after changing the compatibility level. Any ideas?

I've solved my issue by installing an older version of visual studio. I downgraded from 2017 to vs 2015 and it worked like a charm
