I am trying to scaffolf an Entityframeworkcore DbContext for a UWP app from a Sqlite databse. I do:
Scaffold-DbContext \"data source=C:\\SqliteDbFiles\\Sqlite.db
The version of sqlite3.dll used at runtime on UWP won't work at design-time. You can manually download one of the Precompiled Binaries for Windows and copy it to the output directory (e.g. bin\x86\Debug) before running the command.
A simpler solution might be to scaffold the DbContext in a non-UWP project and just copy the classes into the UWP project after they're generated.
