Missing ADO.NET data source for sqlite in Visual Studio 2015
You have to wait for version 1,0,98, due next week https://system.data.sqlite.org/index.html/doc/trunk/www/news.wiki
Links to exact version getting outdated everytime. So instead of trying direct download link go herehttps://system.data.sqlite.org/index.html/doc/trunk/www/downloads.wiki(pretty messy) and find string below on page
This is the only setup package that is capable of installing the design-time components for Visual Studio 2015.
You need to download this one.
also, you can change VS version in your search string.
I had to install this:http://system.data.sqlite.org/downloads/1.0.101.0/sqlite-netFx46-setup-bundle-x86-2015-1.0.101.0.exe
Then i was able to select sqlite data source in VS 2015
Link to the last releases is here https://system.data.sqlite.org/index.html/doc/trunk/www/downloads.wiki
