LLBLGenPro Lite with PostgreSQL and .Net

In this example I used:

LLBLGenPro Lite Version 5.1 (5.1.2) RTM - LITE  Build Date 24-Jan-2017, Licensee: LITE user
Npgsql -Version 3.1.10
CsvHelper -Version 2.16.3
log4net -Version 2.0.7
Visual Studio 2012 with Package Manager Console Host Version 2.8.60318.667

Few tips:

1. Generic part of adapter source code and DB Specific part ( Projects LLBLGenProLite51DBSpecific & LLBLGenProLite51Generic) were created following "LLBLGen Pro Runtime Framework v5.1 Documentation" documentation at llblgen.com/Documentation/5.1/LLBLGen%20Pro%20RTF/index.htm
bitbucket.org/hemantup/orm/src/HEAD/LLBLGenProLite51/LLBLGenProLite51.llblgenproj is the saved project of LLBLGenPro.exe which may be used to regenerate the classes later, if need be.
llblgen.com/Documentation/5.1/LLBLGen%20Pro%20RTF/Tutorials%20And%20Examples/tutorial_createproject.htm

2. The only tweak I had to do to generate the source code (on the top the instructions as mentioned in online help guide "LLBLGen Pro Runtime Framework v5.1 Documentation):
a) Put Npgsql.dll in C:\Program Files (x86)\Solutions Design\LLBLGen Pro v5.1\
b) Some of you might also have to put DbProviderFactories entry under LLBLGenPro_x86.exe.config.
Otherwise you may get error:

Inner exception: <null>

3. In the Console project I created, I had to make DbProviderFactories entry in app.config in addition to installing Npgsql.

For other details, you may refer to comments in bitbucket.org/hemantup/orm/src/HEAD/LLBLGenProLite51/LLBLGenProLite51Console/Program.cs in sample code.
