WebAPIBasicAuthenticationDemo
This project presents a Visual Studio solution including a simple demo ASP.Net Web API Basic Authentication Service Application and a “Tester” Client (Windows Form Application) that allows the user to test the Web API with CRUD operations (GET, POST, PUT, DELETE) that service design requires authentication (except the Get). In addition to demonstrating standard CRUD capabilities, the Web API service implements a .Net Memory Cache (MemoryCache) and custom username and password validator. Passwords are stored securely using Password-Based Key Derivation Function PBKD cryptology. The client “tester” windows form application is not intended as a UX/UI demo but used to test and verify that the backend authentication service allows the user to register with a username and password and verify the Web API CRUD functions based on basic authentication scheme. Lastly, the project is shown in the demo section with a video and screen captures. Note: Every Web API Authentication service should use secure transport. For brevity, this demo project does not implement or discuss the complicated detail nature of SSL/TLS.

A second bonus video and instructions are shown that demonstrate the quick start creation of a web app using the CLI (command-line interface).
Azure-EventGrid-Publisher-Subscriber-Azure-Functions-Demo
In this project, we will create an Event Grid Topic in Azure for a publish-subscribe demo. Our subscriber will be an Azure function that is triggered by an event published to the Event Grid Topic. We will create the Azure function app, subscribe to our Event Grid Topic, and then demo it in action. We will use Postman to set up a POST request to our Event Grid Topic public endpoint that has authentication, version parameter, and the correct JSON body format. After we send the request, we will take a look in the Azure portal to verify the activity and that our subscriber function received and processed the event.

WebAPIMemoryCacheDemo
This project presents a Visual Studio solution including a simple demo ASP.Net Web API Service Application and a “Tester” Client (Windows Form Application) that allows the user to test the Web API with CRUD operations (GET, POST, PUT, DELETE). In addition to demonstrating standard CRUD capabilities, the Web API service implements a .Net Memory Cache (MemoryCache). The client “tester” application also allows the user to verify that the memory cache is implemented correctly and expiring per the set policy. Discussion of the memory cache implementation may help the reader with tips to understand, correctly implement, and verify the cache is expiring. Lastly, the project is shown in the demo section with a video and screen captures.
azure-microservices-functions-kubernetes-demo-project
This project builds an app called "Neighborly". Neighborly is a Python Flask-powered web application that allows neighbors to post advertisements for services and products they can offer. The Neighborly project is comprised of a front-end application that is built with the Python Flask micro framework. The application allows the user to view, create, edit, and delete the community advertisements. The application makes direct requests to the back-end API endpoints. These are endpoints that we will also build for the server-side of the application. Let's deploy an app called Neighborly, allowing neighbors to post advertisements for services and products they can offer. The app will use a blend of Cosmos DB, Azure Functions, Kubernetes, Event Hub, Event Grid Topic, and more.

WCFAuthenticationDemo
This project presents a Visual Studio solution including a simple demo WCF Authentication Service Application and a “Tester” Client (Windows Form Application) that allows the user to test the user registration, login, logout, and service operations. In addition to demonstrating standard authentication capabilities, the WCF service implements a custom username and password validator pattern. Passwords are stored securely using Password-Based Key Derivation Function PBKD cryptology of which the implementation is discussed. A custom error handler ensures that exceptions are properly wrapped into WCF Faults and communicated to the client caller. Certificates are discussed along with how to implement a server certificate on a client machine for development testing of “integrity” and application trust. The project includes a demo certificate and script for generating self-signed dev certificates, which must be installed into the client certificate store for the client tester application to trust and access the demo service. The client “tester” windows form application is not intended as a UX/UI demo but used to test and verify that the backend authentication service registration, login, logout, service operations, and callbacks are working as expected and sending proper WCF fault messages. Lastly, the project is shown in the demo section with a video and screen captures.

MyAzureWCFServiceDemo
Positive Affirmations is a WCF service demo project hosted via Azure Cloud Services. A Windows Form Application functions as a test client where users can consume the service. This project presents a simple WCF Positive Affirmations Service that demos architectural styles of setting up, hosting via Azure Cloud Services, configuring services, and testing the service for http protocols. The service accepts a simple string, which represents a name, and returns a simple string with a randomized positive affirmation that acknowledges the name. Instead of using IIS Express, the simple service is hosted using Azure Cloud Services. The Visual Studio solution also has one client “tester” Windows Form application that tests the http protocol connection to the hosted service.

ServiceConcurrencyDemo
Concurrency and Instancing in WCF Services – A Demo of Service Concurrency and Instancing Behaviors with Multi-threading Clients: This project presents a simple Demo WCF Service and “Tester” Client Application demonstration that implements concurrency and instancing behaviors on a service with multiple client thread calls to a method on the service. The Demo Service is a standard template WCF service application hosted by the development IIS. The service features one simple method… a test method that simulates a long running process (it sleeps for 3 seconds). The client “tester” is a simple console application that creates multiple threads that access the service and report back on the results. The objective of this project was not to demo setup and hosting of a service, nor the client interface, but retrieve and display results of service behaviors with respect to multi-threaded access. Discussion regarding the hosting and setup of the simple IIS hosted service application will be skipped in this project article.
ServiceErrorHandlerDemo
Simple Service Error Handler – A Demo of a WCF Self-Hosted Service & Client "Tester" Windows Form Application Exchanging Error Messages : This project presents a simple Math Service and Client Application demonstration that implements error handling on the service and communications of its errors to the client. The Math Service is a self-hosted (service host) WCF application launched and managed with a simple console interface. The client “tester” has a simplified GUI user interface to quickly demo and test the service (Windows Form Application). The GUI has features to add, subtract, multiply, and divide two numbers (integers). The GUI does basic data validation then sends a request to the math service. After it receives the results from the math service, it displays the calculation result or any received error messages (faults) to the user. The objective of this project was not to demo a calculator application but the handling of errors on a service.
ServiceThrottlingDemo
Service Throttling in WCF Services – A Demo of Service Concurrency and Instance Throttling Behaviors with Multi-threading Clients: This project presents a simple Demo WCF Service and “Tester” Client Application demonstration that implements concurrency and instancing behaviors on a service with multiple client thread calls to a method on the service. The project also demos throttling service behaviors that are in the service configuration settings. Service throttling limits the client calls that could otherwise drain or slow down its service to other clients if too many are calling simultaneously. The Demo Service is a standard template WCF service application hosted by the development IIS. The service features one simple method… a test method that simulates a long running process (it sleeps for 5 seconds). The client “tester” is a simple console application that creates multiple threads that access the service and report back on the results. The objective of this project was not to demo setup and hosting of a service, nor the client interface, but retrieve and display results of service behaviors with respect to multi-threaded access. Discussion regarding the hosting and setup of the simple IIS hosted service application will be skipped in this project article.
