问题
What I did is,
1) Created a project in vs2015 (.Net Framework 4.6) 2) Installed System.Data.SQLite from Nuget. Actually System.Data.SQLite(1.0.105.1),System.Data.SQLite.Core(1.0.105.1),System.Data.SQLite.EF6(1.0.105.1),System.Data.SQLite.Linq(1.0.105.1),EntityFramework(6.0.0) were installed 3) Updated EntityFramework to 6.1.3 in Nuget 4) Tried to create Entity Data Model from a local Sqlite database 5) Rebuilded the whole solution
But when I tried to create a new database connection, SQLite connection was not appearing in the data source.
Can anyone figure out this issue?

回答1:
AFAIK the designer support is not included in the nuget packages of SQLite: you will need to install the package that is indicated for the version of Visual Studio that you are using.
According to the System.Data.SQLite downloads page currently the only package providing designer support in VS 2015 are the Setups for 32-bit Windows (.NET Framework 4.6) sqlite-netFx46-setup-bundle-x86-2015-1.0.105.1.exe (16.93 MiB), which contains the following sentence in its description:
This is the only setup package that is capable of installing the design-time components for Visual Studio 2015.
