Programming in Practice - set of examples targeting education purpose.

Hi there 👋

About

I have 35+ years of experience in designing and deploying highly distributed applications having managed 100+ innovative projects for industry including aviation, heat engineering, power engineering, and mining. I am the author of the “Process Observer” concept, the architect of the CommServer™ communication software package for the management and optimization of data transfer, author and architect of the SmartFactory™ workflow management system

For 14 years I have been an active member of the OPC Foundation involved in projects related to the OPC Unified Architecture design, adoption, deployment, and maintenance.

I am engaged in many research projects as a researcher, university teacher, and scientist. I am the author of 40+ publications, lectures, presentations, and training sessions. I have a degree of Master's of Electrical Engineering from the Technical University of Lodz and a Ph.D. in Process Control Engineering and Robotics.

I am the founder and Executive Director of CAS.

My current goal is to find an opportunity to manage the research/deployment of innovative IT solutions.

tp's Issues

Biathlon - provide description in English

This project is documented using English so any text should be provided in this language.

Change the folder name ConstructorInjectionUnitTest => DependencyInjectionUnitTest

Follow the project name

TPA - add project with reflection example

Converge the example code and the project.

Add another DI example - Biathlon

This project has been presented during labs.

AP TypeBuilder Class Example

Starting point;

TypeBuilder Class

Scope: much simpler example as in the above article

AP - Add an example how to use the application domain

Starting point:

• Using Application Domains
• AppDomain Class
  Scope

Add unit tests to Reflection

create new folder in the UT project.
Add UT to Model layer
Add UT to VM layer.

mvvm - add fetch data button

Now data is created by the VM and should be fetched using the user interface.

Review the TreeViewExample

• From diff it seems that the namespace must be changed to follow the folder name
• remove App
• remove application configuration.

AP - add example for Add-ins and Extensibility

Starting point

Add-ins and Extensibility

Scope

The example must load the add-in into additional application domain.

Serialization example xml translation doesn't work with Google Chrome.

@wiktorwandachowicz reported that the example works with MSIE or Firefox, and these two perform XML to HTML XSL transformation using catalog.xslt file.
Google Chrome doesn't - it must be investigated.

Add UnitTests to the MVVMLight implementation

• ViewModelBase
• RelayCommand

Add serialization example

The following topics are to be ilustrated:

• static class and static elements
• object state
• singleton
• state machine
• serialization
  • manual serialization
  • reflection based serialization

AP - add reactive extensions example

Starting point:

• Reactive Extensions
• Reactive-Extensions/Rx.NET

Scope

• simple timer case
• simple producer consumer case

TPA Example of static tracing

Starting point
Trace Class

TPA - add example how to use Trace​Source Class

Starting point:
Trace​Source Class

TPA - IServiceLocator example

The CommonServiceLocator library provides an abstraction over IoC containers and service locators. Using the library allows an application to indirectly access the capabilities without relying on hard references.

The to get the description visit the project website:
commonservicelocator

The nuget package is available at:
CommonServiceLocator

The package may be added to the project directly using VS.

This interface may be added to:
LocalizedDescriptionAttribute.cs
or in an independent project.

Scope:

1. Using the interface instead of static property
2. An implementation of a resolver must be provided in UT project.

Add LINQ examples

Port to VS 2015

2013 is not longer use.

Refactoring the repo structure - separate DI

Created independent solution for the DI example.

TPA - provide dynamic source code generation example

Starting point:

Dynamic Source Code Generation

Scope

Try to regenerate source code (only type definitions) from TypeMetadata.cs located in TP/TPA/Reflection/Model/

Add comments to public members

All public members must have description.

Generics - add example

• Types
• Methods
• Default value
• where clause.

TPA: CSharpCodeFactory is in nested namespace by mistake

The target namespace should be:

TPA.Reflection.CodeGeneration.CSharpCodeFactory

Dependency injection example

• Interface providing trace functionality
• UT implementation logging in the list
• Console application logging to the Console.

TPA - Add filter to the semantic logging

Starting point

Add filter according to this guideline Creating a custom event filter

Scope

• Define the filter in the UT project
• Call a method generating 100 verbose events and an error event at the end of loop.
• Test if only last event are returned from the filter.

Create solution for mvvm example.

It must contain

• Solution folder folder
• WPF application
• UT project

TPA Using Dynamic Objects Example

Starting point

Walkthrough: Creating and Using Dynamic Objects

Scope

• added and implement method derived for DynamicObject allowing to use property name as a string to search a text file.
• add UT
• add text file

TPA - Example of the Monitor class

Starting Point:
Overview of Synchronization Primitives

TPA - add application architecture example

• application top - down reference model
• recursion

AP - create UT for `CreateInstanceFactory`

 `TPA.Reflection.Execution.CreateInstanceFactory`

TPA - Reflection method and property get/set call example

TPA - Reflection method and property get/set call example

Starting point:

• PropertyInfo Class
• MethodInfo Class

TPA: Add example for Dynamic Language Runtime

Scope:

1. dynamic
   • compare dynamic and object
2. Using Type dynamic
3. Dynamic Language Runtime Overview

TPA Localizability example

Goal

To provide an example of developing of an application that can be localized into one or more languages.

Key points;

Ensure that:

• the application can be localized easily
• that the executable code is separated from its resources (loosely coupled)

To get more visit:

Globalizing and Localizing .NET Framework Applications

TPA Separation of concerns - MEF example
