Updated C# Reference Implementation

I have updated my C# reference implementation and included FluentValidation on some of the DTO objects. I also updated the ErrorMap to include validations on the server side as well as on the WPF client side. This version also includes a sample SQL Server Persistence Provider. As always, you can get the latest code on my GitHub repo.

Slides for Sacramento .NET User Group

Update 04-05-2015: I completed the SQL Server Provider. Latest code is on GitHub.

I had a lot of fun presenting last night at the Sacramento .NET user group. It was great to hear that people learned a lot and are looking forward in incorporating the things they have learned about the Provider Model design pattern and object persistence in general into their own projects. The slides are available for download here. The source code of the entire reference implementation is available here. I will be finishing up the SQL Server provider within the next few days and make it available in my GitHub repo.

Object Persistence Reference Implementation

I’ve been updating my reference implementation in the last few days. I’m actually using this reference implement in my own projects. You can download the latest version on my GitHub repo.

This is a complete .NET C# reference implementation to help you jump start a service oriented system running in a cloud environment such as Amazon’s EC2 or on-premis clusters.

This reference implementation shows you how to build a client and the server side. The client side is a sample WPF application that communicates via http REST requests using JSON payloads to the service side. Of course, you can use any type of client as long as the client can communicate via http and REST based JSON’s.

The service side is using a Web API 2 service layer that communicates to a central domain model. The service side demonstrates how to handle exceptions and edge cases and how to communicate failure to the client.

The persistence layer demonstrates the extreamly powerful provider pattern to store the domain objects into the following databases:

  1. db4o (an object database)
  2. Redis (a NoSQL database)
  3. SimpleDB (a NoSQL database)
  4. SQL Server (comming soon)

Please note that the entire system has no knowledge on how the objects are stored. All implementation details are in the individual providers listed above. This means that you can switch the persistence provider without having to recompile and therefore switch a running system from one persistence store to another.

I will try to create a sample SQL Server provider soon.

Visual MASM IDE 1.0 is Released

I’m prouVisualMASM_1_0-Maind to announce the first release of my Visual MASM IDE 1.0. With Visual MASM, you can program assembly applications for Windows 32-bit, Windows 64-bit, and even MS-DOS 16-bit COM and EXEs. Visual MASM uses Microsoft’s powerful Macro Assembler but makes it easier to manage all of your Windows assembly programs. I have included simply Hello World applications that range in size from 254 bytes (COM file) to a whopping 2,5 Kbytes for a Windows 32-bit and Windows 64-bit application. Head on over to http://www.visualmasm.com and download it, it’s free.

I’m a confirmed speaker at the appsworld North America 2015 at Moscone Center West, May 12-13 in San Francisco, CA.  Discover the future of multi-platform apps. See all confirmed speakers. This sure will be an exciting event. I’m still working on my presentation that will include Redis, Amazon AWS, C#, and more. I will see you there.

Intel Galileo Gen 2 and Windows 10

Intel Galileo Gen 2

Intel Galileo Gen 2

As there were not enough reasons already to write Windows applications in assembly (see my Visual MASM project site), I just found out yesterday about some great new development in the SoC (System on a Chip) industry. Intel came out with the Intel Galileo Gen 2 which features a full blown 586 Pentium class computer. What’s so awesome? It’s super tiny and just a little bigger than a credit card. So, you can install and run Windows or Linux on it. How freaking cool is that? No noise and about 5 Watts of power consumption… the possibilities are incredible. Put Windows 10 on it for free, here is how. Create your Windows applications in MASM and my Visual MASM, off you go… amazing. Go check out Microsoft’s Internet of Things(IoT).

Presenting “Object Persistence in C#” in Sacramento, CA, March 25th, 2015

Wednesday, March 25th, 20015, I will be presenting “Object Persistence in C#” at the Sacramento .NET User Group (SAC.NET) at the Microsoft Office at 1415 L Street, Suite 200, Sacramento, CA 95814 starting at 6:00 pm. Maria Martinez, Co-Organizer, Sacramento .NET User Group, was kind enough in helping to get this organized. Thank you Maria. I will see you there.

Presenting “Object Persistence in C#” at Bay.NET User Group on April 9th, 2015

I will be presenting “Object Persistence in C#” at the Bay.NET user group at the Berkeley City College located at Room 451A, 2050 Center Street, Berkeley, CA from 6:15 pm – 9:00 pm.

Deborah Kurata, Co-Organizer, East Bay Chapter Leader, was kind enough in helping to get this organized. Thank you Deborah.

I will see you there.

Object Persistence, Part 5 – Video – Redis Provider

In part 4 of this series, I went through the entire Visual Studio solution and also showed the db4o object database provider.

In part 5, I’ll show you how to store your Plan Old C# Objects (POCO) into Redis using the Redis Cloud at redislabs.com service. We will build the Redis Provider and take it out for a spin storing our new domain objects.

You can download the source code at GitHub.

Object Persistence, Part 4 – Video

In part 3 of my Object Persistence series, I introduced the complete Visual Studio 2012 source code.

This is part 4 of my Object Persistence series. I created a detailed video that goes thru all the parts in the solution. Enjoy! Make sure you continue with part 5 where we build a Redis persistence provider.
