SQLite EF6 error - entity-framework

Question

Im using win10, vs2017.
I created a new project, then added nuget "System.Data.SQLite".
Next, I installed "sqlite-netFx46-setup-bundle-x86-2015-1.0.105.2.exe" from system.data.sqlite.org with fullInstall options and checkboxes.
I rebooted the PC.
Then in the Visual Studio Server Explorer, I connected a new SQLite Database.
Further added "ADO .Net Entity Date Model", added Entity and used "Generate DB from model"
Im getting this error:

This feature does not work for SQLite, as hinted at in the tt file:
<#
if (this.IsSQLCE) {
#>
-- Entity Designer DDL Script for SQL Server Compact Edition
<#
} else {
#>
-- Entity Designer DDL Script for SQL Server 2005, 2008, 2012 and Azure
<#
}
