Here are various was to convert enums to a lists
The idea is to use Enum.GetValues() method to get an array of the values of the constants in the enum. To get an IEnumerable<T> of all the values in the enum, call Cast<T>() on the array. To get a list, call ToList() after casting.
As defined by Polly “A circuit breaker detects the level of faults in calls placed through it, and prevents calls when a configurable fault threshold is exceeded”.
Continue reading Circuit BreakerPolly is classed as a resilience framework. A resilience framework is a set of libraries that help an application to recover from transient or more extended failures in services or infrastructure upon which it depends. When recovery is not possible, the resilience framework will facilitate graceful degradation of your application.
Polly has been around for many years and has been tried and tested in many applications

Continue reading Fault tolerance using PollyThrottling and rate-limiting allow you to prevent abuse of your API and ensure that your API withstands large numbers of calls (including DoS and accidental loops). With Throttling, you can set a delay on calls after an SLA tier has been exceeded, slowing down the number of requests an API client is making.

Continue reading Asynchronous Programming the right wayJSON Web Tokens is an emerging standard. They are very close to their standardisation. IETF has taken care of that, and OpenID connect mandates the use of JSON Web token for all of the tokens that are exchanged in that protocol. this article gives you a little look, an overview of the purpose of security tokens, and, and what other types of tokens we have out there and where, where they are used. Then we have a look at the structure of a JSON Web Token, and then we’ll show you how easy it is to create and consume them using the Microsoft DotNet Core development framework.

It is loosely based on creating a simple REST Client, an tutorial from Microsoft can give you the very basic features in DotNet Core

Build an image from the Dockerfile in the current directory and tag the image
docker build -t myimage -f Dockerfile .List all images that are locally stored with the Docker Engine
docker ps -aDelete an image from the local image store
docker image rm CONTAINER_NAMEYou may want to remove all orphaned images, you can do this with dandling field
docker rmi $(docker images -f dangling=true -q)I came across this guide as it is an introduction to developing microservices-based applications and managing them using containers. It discusses architectural design and implementation approaches using .NET Core and Docker containers. To make it easier to get started with containers and microservices, the guide focuses on a reference containerized and microservice-based application that you can explore. The sample application is available at the eShopOnContainers GitHub repo.
