问题
I have a similar problem with what is posted here:
SQLite connection not appearing in Entity Data Model Wizard
Except that I use VS2015 and I cannot even see the connection for SQLite in my Server Explorer:
I already install System.Data.SQLite from nuget and using Entity Framework 6.1.3 and this setup:
sqlite-netFx46-setup-bundle-x64-2015-1.0.102.0
which is available in: https://system.data.sqlite.org/index.html/doc/trunk/www/downloads.wiki
But the option just doesn't appear.
回答1:
The problem was with the bundle setup used, it is the bundle setup for VS2015 for Windows 64-bit. While the bundle setup capable of adding the Designer components in the VS2015 is only the bundle setup for VS2015 for Windows 32-bit.
Setups for 32-bit Windows (.NET Framework 4.6)
This setup package features the mixed-mode assembly and will install all the necessary runtime components and dependencies for the x86 version of the System.Data.SQLite 1.0.102.0 (3.13.0) package. The Visual C++ 2015 Update 2 runtime for x86 is included. The .NET Framework 4.6 is required. This is the only setup package that is capable of installing the design-time components for Visual Studio 2015.
In other words:
sqlite-netFx46-setup-bundle-x86-2015-1.0.102.0
instead of
sqlite-netFx46-setup-bundle-x64-2015-1.0.102.0
When I use the x86 bundle, it is OK:
