I tried to install EntityLite 1.12.1 and Npgsql 3.1.9 for this. [ in .Net 4.5 targeted console app] But ended up with error:
In case of other ORM's similar error was resolved by DbProviderFactories entry in app.config of the same project. But in case of EntityLite 1.12.1, I had to put Npgsql 3.1.9 dll in gac and make DbProviderFactories entry in devenv.exe.config.
But still my datalayer was not generated. Now I got the error:
EntityLite 1.12.1 was released back in September 15, 2015 and targeting .NETFramework 3.5 Client. This could have been the culprit for Specified cast is not valid. So I removed previously installed dll's in GAC and DbProviderFactories entries in devenv.exe.config. If you follow step by step actions mentioned below, you may avoid such errors I faced as mentioned above:
0. create a database ,a table as mentioned in comment section of bitbucket.org/hemantup/orm/src/HEAD/i_nercya_EntityLite_1121_generate/Program.cs
1. Create a project targeting .Net 3.5:
2. In this project if you try to install npgsql anything above 2.2.7, you get error like as mentioned below:
PM> Install-Package Npgsql -Version 3.0.0-beta0001 -Pre
Installing 'Npgsql 3.0.0-beta0001'.
Successfully installed 'Npgsql 3.0.0-beta0001'.

Uninstalling 'Npgsql 3.0.0-beta0001'.
Successfully uninstalled 'Npgsql 3.0.0-beta0001'.
Install failed. Rolling back...
Install-Package : Could not install package 'Npgsql 3.0.0-beta0001'. You are trying to install this package into a project that targets '.NETFramework,Version=v3.5', but the package does not

So you have to go for Npgsql 2.2.7

3. Now go for EntityLite 1.12.1 ( dependencies are resolved here):

4. Retrieve the full name of dll's:
C:\YourProjectPath\packages\Npgsql.2.2.7\lib\net35\Mono.Security.dll
C:\YourProjectPath\packages\Npgsql.2.2.7\lib\net35\Npgsql.dll
Code for retrieving name is in bitbucket.org/hemantup/orm/src/HEAD/i_nercya_EntityLite_1121_generate/Program.cs
5. Install these two dll's in gac:
C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC>gacutil -i "C:\YourProjectPath\packages\Npgsql.2.2.7\lib\net35\Mono.Security.dll"
C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC>gacutil -i "C:\YourProjectPath\packages\Npgsql.2.2.7\lib\net35\Npgsql.dll"
6.1 In C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\devenv.exe.config ( or the respective config of devenv.exe, as per your installation, you may get path for devenv.exe by viewing the properties of VS shortcut.) make DbProviderFactories entry like:
<system.data>
<DbProviderFactories>
.
.
.
<remove invariant="Npgsql" />
.
.
.
<add name="PostgreSQL Data Provider"
invariant="Npgsql"
description=".Net Data Provider for PostgreSQL"
type="Npgsql.NpgsqlFactory, Npgsql, Version=2.2.7.0, Culture=neutral, PublicKeyToken=5d8b90d52f46fda7" />
</DbProviderFactories>
</system.data>
Just make sure you use correct assembly fullname as retrieved in step 4
6.2 Restart Visual studio
7. Copy paste code similar to as mentioned in the attached code's bitbucket.org/hemantup/orm/src/HEAD/i_nercya_EntityLite_1121_generate/DataLayer.tt. Right click on this tt file and click "Run Custom Tool".
Save DataLayer.cs generated for later use in a separate folder for future use.
8.1 Close Visual studio.
8.2 Remove DbProviderFactories customization you did in 6.1
8.3 Remve the two dll's as in step 5, from gac
C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC>Gacutil -u "Npgsql, Version=2.2.7.0, Culture=neutral, PublicKeyToken=5d8b90d52f46fda7"
C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC>Gacutil -u "Mono.Security, Version=2.0.0.0, Culture=neutral, PublicKeyToken=0738eb9f132ed756"
So, bitbucket.org/hemantup/orm/src/HEAD/i_nercya_EntityLite_1121_generate/DataLayer.cs generated in step 7 is your output of this activity.
