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.
