CommonHelpers 1.0.5

CommonHelpers

This is a small NET Standard 2.0 helper library to reuse code that I write several times a day in demo projects.

Nuget: CommonHelpers on NuGet

Highlights

Collections

Special collection types that help in special scenarios (e.g. ObservableQueue and ObservableRangeCollection).

Common

This folder has some of the most frequently used classes (i.e. BindableBase, ViewModelBase, JsonHelper).

Models

Common sample data model classes used to populate UI elements (Charts, ListViews, DataGrid, etc).

Extensions

Extensions for commonly used objects like string, DateTime, enum. There are also some special extensions for File, Exception and Color. Finally, there's a unqiue helper, HttpClientExtensions which provides download progress and helper method to POST image data.

MVVM

Platform agnostic MVVM classes like DelegateCommand and RelayCommand

Services

To make testing UI controls easier by quickly providing well formatted data from offline sample data and online API endpoints. This is really useful for quickly testing Load On Demand scenarios.

• BingImageService
• ComiceVineApiService**
• SampleDataService
• XkcdApiService

** Note: Most services do not require an API key, just new up the class and go. To prevent any confusion, any services that need an API key will require it in the constructor.*

Example 1 - Sample Data Services

SampleDataService:

var sampleDataService = new SampleDataService();

listView.ItemsSource = sampleDataService.GeneratePeopleData();
scatterLineSeries.ItemsSource = sampleDataService.GenerateScatterPointData();
barSeries.ItemsSource = sampleDataService.GenerateCategoricalData();

Example 2 - Online API Services

BingImageService:

using (var bingImageService = new BingImageService())
{
    var result = await bingImageService.GetBingImageOfTheDayAsync();
    image.Source = new UriImageSource{Uri = result};
}

Tip: If you're looking for more public APIs to use for data sources, check out Todd Motto's Public Apis on GitHub. If you see any in there that you'd like me to create a C# service class for? Open an Issue and I'll add it.
