Design Patterns in .NET Training in Finland

We can host this training at your preferred location. Contact us!

This course is designed for C# developers who want to extend their architectural skills using design patterns and related techniques. The delivery is tailored to the .NET platform and uses .NET libraries and frameworks wherever possible to illustrate how patterns can be usefully applied. Additional examples are drawn from Ruby, Java/JEE, C++ and Scala.

Each pattern is introduced in terms of its abstract structure (via UML diagrams), its benefits and drawbacks, sample implementations and practical examples of how it can be used to simplify software development.

Delegates should have at least 3 years experience in C# development and be familiar with UML Sequence and Class diagrams.

The Decorator and Adapter Patterns

Using composition to layer extra functionality
Applying Decorator to create specialized collections
Distinguishing between Adapter and Decorator
Uses of these patterns in the .NET I/O libraries

Visitor

Simplifying class design by modelling operations as visitors
Adding support for Visitor to existing collections of objects
Using Visitor to add reporting and logging behaviour
Code generation in C# with Visitor and the CodeDOM library
Using Visitor in the design of a C# mock objects generator

The State Pattern

Benefits of the State Pattern over subclassing
Modelling objects with complex internal state transitions
Different approaches to implementing state transitions
Automatically generating state machines

Parallel Programming Patterns

Introducing the .NET Parallel Patterns
Working with thread pools and IOU’s

Design Patterns in .NET Training Course in Finland

Finland is a country located in northern Europe. Helsinki is the capital and largest city of the country. The majority of the people are Finns but there is also a small Lapp population in Lapland, where the country is famous for the Northern Lights. Finland's national languages are Finnish and Swedish.

Known for its vast forests, lakes, and natural beauty, Finland is one of the world's largest producers of forest products, such as paper, pulp, and lumber. One of the world's largest sea fortresses Suomenlinna, Rovaniemi with the "White Nights", dogsled safaris and of course the Northern Lights are what makes Finland so popular for tourists. Finland is one of the best places in the world to see the Northern Lights and attracts millions of tourists during its seasons.

Finland is home to a thriving technology industry and is widely recognized as one of the world's leading technology hubs. Companies such as Nokia and Rovio (creator of the popular game Angry Birds) are based in Finland. Some of the key factors that have contributed to Finland's success in technology include; strong investment in research and development, a highly educated workforce and fundings.

Finland has a strong educational system, and is widely regarded as one of the world's most literate countries. In fact, Finland's literacy rate is one of the highest in the world, and its students consistently perform well in international tests of math and reading ability.

Also, as a pioneer in environmental sustainability, Finland is known for its efforts to reduce its carbon footprint and promote clean energy. This Nordic country is also famous for its unique and distinctive cultural heritage, including its traditional folk music and its elaborate traditional costumes.

Helsinki, Finland's capital city, is the country's business center. Helsinki is Finland's largest city, and it is home to many of the country's major corporations and organizations, including many of the country's leading technology firms. The city is also a commercial, trade, and financial center, as well as one of the busiest ports in the Nordic region.
