Using async/await in .NET 3.5 and 4.0

.NET 4.5 introduced the async and await keywords, simplifying asynchronous programming as much as possible. But did you know that you can also use async/await in .NET 4.0 and even .NET 3.5?

Thanks to the following NuGet packages, you can bring the power and simplicity of async/await to your older applications:

This package enables Visual Studio 2012 projects to use the new 'async' and 'await' keywords. This package also includes Task-based extension methods that allow using some of the existing asynchronous APIs with the new language keywords. Windows Phone Silverlight 8 projects can use this package to get access to async extension methods for the networking types.

This package is not supported in Visual Studio 2010, and is only required for projects targeting .NET Framework 4.5, Windows 8, Windows Phone Silverlight 8, or Windows Phone 8.1 when consuming a library that uses this package. For known issues, please see: http://blogs.msdn.com/b/bclteam/p/asynctargetingpackkb.aspx.

For more information on the async programming model, visit MSDN: http://msdn.microsoft.com/en-us/library/vstudio/hh191443.aspx.

Supported Platforms:

- .NET Framework 4 (with KB2468871)

- Windows 8

- Windows Phone 8.1

- Windows Phone Silverlight 7.5

- Silverlight 4

- Portable Class Libraries

Adds the new C#5 async features for .NET 3.5 projects

.NET 8–Keyed/Named Services

A feature that a lot of IoC container libraries support but that was missing in the default DI container provided by Microsoft is the support for Keyed or Named Services. This feature allows you to register the same type multiple times using different names, allowing you to resolve a specific instance based on the circumstances. Although there is some controversy if supporting this feature is a good idea or not, it certainly can be handy. To support this feature a new interface IKeyedServiceProvider got introduced in .NET 8 providing 2 new methods on our ServiceProvider instance: object? GetKeyedService(Type serviceType, object? serviceKey); object GetRequiredKeyedService(Type serviceType, object? serviceKey); To use it, we need to register our service using one of the new extension methods: Resolving the service can be done either through the FromKeyedServices attribute: or by injecting the IKeyedServiceProvider interface and calling the GetRequiredKeyedServic...

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t...
