When using DDD with ES, CQRS, events are used in four ways: 1) they are used to reconstitute aggregate state 2) they are used to build read model 3) they are used to drive back-end workflows 4) they can be used as audit log The flow of events in ES model is: You can use standard approach of working with tables representing state of aggregates, or whatever persistence approach is in place,

I created small extension for Visual Studio 2015, allowing to write .proto files with Google Protobuf definitions, and generating C# code on save. The extension is really a custom tool for .proto files. The code is available on github To use it -  - clone the repo,  - build the solution - navigate to bin\Debug\ and run ProtobufCSharp.vsix - run Visual Studio 2015,

As I already blogged recently - I build application using Domain Driven Design, Command Query Responsibility Segregation and Event Sourcing patterns. I want to post implementation details of Sagas and Process Managers In my implementation both - Sagas and Process Managers consume event messages and execute some actions in response. Saga has no state while Process Manager has. Another

In my latest application I use Domain Driven Design, Event Sourcing and Command-Query Responsibility Segregation patterns. I implemented ES infrastructure layer for SQL Server. To read events back from event store I use polling mechanism and also "fast channel" (you can read details here) I need to read events for two reasons: 1) To build read model 2) To process events by using Process

Often we need to quickly animate something on the screen without initializing storyboards, animations, setting targets etc. Also sometimes we need to be able to change animation direction or target value. All this is about double animation. Suppose we need to move a scroll viewer vertical offset with some speed but depending on user actions we may change speed and even direction of scrolling.

Today I found rather strange problem.I was getting strange exception from MS internal code related to bindings.The exception was raised when code was trying to set SelectedItem of DataGrid control.Stack Trace is very large but most important lines are as follows:Message: Object reference not set to an instance of an object.

  Today I decided to format all .xaml documents in a solution so that all attributes are placed on a separate line and also to line nested tags on correct positions. Actually I already setup settings in Visual Studio Tools menu a long time ago, but some developers working on the same project forget to format documents before check in – the result is - to comfortably read the file in

I tried to solve a number of performance problems while tuning WPF application I work on currently. One of things I wanted to do is – make bindings effective only when control that uses them becomes visible, and don’t update binding target when target is invisible. I end up creating the markup extension allowing me to do so. Just use markup extension in format “{namespace:VisibleBinding

The old one was AMD Athlon-64 5400 Dual Core CPU 2 Gb DDR 2 RAM memory 250 Gb HDD Well it worked, but it became slow with years – VS versions and heavy apps load this CPU and memory with ease.

When I work on WPF projects I like very much the Snoop application. It allows me to debug visual tree of WPF app and look into what properties of controls are having what values in real time – to see what can be done to improve layout (like fixing margins etc.), what data bindings and data contexts are currently used and many other things. If you did not try Snoop – just try it – it is free and

Not long time ago, I faced the following requirement: Company uses custom Data Access Layer, which is developed within company and which does not have any designer tool as Entity Framework or Linq to SQL frameworks have.

  Coding standards is important to have in any software organisation.

Be aware of the following possible reasons of memory leaks in WPF applications: Don’t register non-static handlers using EventManager.RegisterClassHandler for example if you register handler using this code: Declare the handler as static ! Otherwise this will cause memory leak. See also: WPF possible memory leak with EventManager.RegisterClassHandler Try to avoid

I created another nice ASP.NET AJAX extender for GridView. With it's help you can enable inline editing for Grids in web pages relatively faster, comparing to time needed to implement this feature from scratch using pure JavaScript. For example having the following GridView on the page: You can add an extender that allows editing of values of cells right in place: Extender has inner

Currently I work on a big project with quite a big amount of UserControls in it. Many controls in the system have quite complex markup. And often I need to reference controls residing in the naming containers, or simply inside another controls. for example if you have the markup like this: you cannot simply reference control name rb1 or rb2 from the code behind of that control. So I use

I have created ASP.NET AJAX Extender control. It extends GridView control fixing it's header on the top while adding vertical scroll bar to it's contents. The control also supports maintaining scroll position inside grid between postbacks. The control works fine inside or outside of UpdatePanel.   To extend GridView, just drop extender onto the design surface and set its TargetControlID:
