I am new to PostgreSQL and as a company, we have found out that PostgreSQL is better than SQL Server on processing online transactions and we have reached a conclusion to migrate from SQL Server to PostgreSQL.
I have bought DBConvert to successfully migrate the database from MS SQL Server to PostgreSQL and that is just fine, all data has been transferred. Now, the problem comes when I now have to move my visual studio from EF to PostgreSQL. I have researched how best I could really do this. This Article is not detailed enough:
Migrate EF6 database-first from SQL Server to PostgreSQL
An several aren't detailed enough. Can anyone assist me in a step-by-step approach on how best I could do this?
Well, I finally found that the only way to successfully move from Visual Studio Entity Framework to PostgreSQL, you have to use the Code First Approach.
There is no scaffolding solution I found to do the conversion. You will have to install the Npgsql Provider, change the connection string to point to PostgreSQL, and also install the Npgsql.EntityFramwework and make sure your models have been changed accordingly.

This is my first time building a .NET application that connects to a DB2 database, and I really have no idea where to begin as I've never worked with DB2 before.
Here's what I've done so far:
Installed IBM.Data.DB2.EntityFramework
Installed IBM.Data.DB2.iSeries
Installed Entity Framework 6
Now when I try to create a code first model, I don't see DB2 in the list of available data sources, so I'm guessing I need to figure that out first.
What do I need to do to get DB2 added as a data source? I know it's possible because I can see it in the first screenshot in this previously answered question.
you have to install IBM Data Server Client Packages and IBM Database Add-Ins for Visual Studio
I've got an SQLite database defined by an SQL DDL (CREATE TABLE etc.) script and am to derive Entity Framework model classes to work with it.
In the past, when I had an opportunity to try Visual Studio 2013 Ultimate and Microsoft SQL Server in the same situation, Visual Studio allowed me to use "database-first" approach and reverse-engineer the model to create the model classes automatically. But I can't find anything like that available in Visual Studio 2015 Community and SQLite.
Am I missing something or are there, perhaps, 3-rd party tools that can do the job to set me free of mechanically typing all the model code manually?
If you use VS Express you are out of luck, since you cannot install DDEX providers or any other extensions using that edition. Use Community, the download sqlite-netFx46-setup-bundle-x86-2015-1.0.104.0.exe from http://system.data.sqlite.org/index.html/doc/trunk/www/downloads.wiki (see my blogpost here for detailed info: http://erikej.blogspot.dk/2014/11/using-sqlite-with-entity-framework-6.html )
If you use EF Core, upgrade to Community, and install the latest daily of my VS extension SQLite Toolbox, which has a feature to generate an EF Core Model via GUI https://github.com/ErikEJ/SqlCeToolbox/wiki/Release-notes
I know the EF Power Tools offers this but am loath to install them after installing VS2013 Update 2 since some of the Power Tool features are now part of Update 2. I already spent a good part of yesterday reinstalling VS2013 w/ integrated Update 2 after installing/uninstalling EF 6.1.0 Tools broke using the ADO.NET project templates. Is there anything built into Update 2 that allows this?
Honestly, the quickest way is usually by generating a database diagram via SQL Server Management Studio. Assuming the database has been generated, and your question is meant purely as a visual representation of the model.
What DB Management Systems does EF 4.2 Code First support?
I'd like to use Code First with MySQL and Oracle. Do I have to download extra things?
Thanks!!
It supports the most of the popular DBMS's like Oracle, MySQL, PostgreSQL and SQLite other than SQL Server. Yes you have to download database connectors for them. Here is a good tutorial to get you started.
Has anyone managed to use Postgresql as a datasource for SSAS? The Postgresql .NET connector seems promising, but the SSAS view wizard does not seem to be able to see the tables in the database.
Try using the ODBC connector. I've had success getting other tools to connect to PG using it. The EnterpriseDB installers not only include a well packaged, working version of PG for windows, they include working, correctly installed drivers.

try pg_bulkload for load from via c# & from mssql to pgsql
copy & bcp (ssis) for second direction (pgsql->ssas)

It is actually possible to hack the Postgresql .NET connector and implement a "MSSQL compatibility mode", where the [ and ] around tables and schema names are removed. Using this, the list of tables does not appear in MS SSAS, but it is possible to replace them by views.
