WCF Tutorial for Beginners: Learn to Create Reliable Service-Oriented Applications

Windows Communication Foundation (WCF) is a powerful framework from Microsoft that is used to build service-oriented applications. If you're new to this, don’t worry! This WCF Tutorial for Beginners will guide you through the basics to help you understand how WCF works and why it’s essential for creating secure and scalable services.

WCF allows applications to communicate with each other, even if they are on different platforms. For example, you can use WCF to connect a web application running on Windows to another service running on Linux or mobile devices. It supports protocols like HTTP, TCP, and named pipes, making it versatile for different networking needs.

Why Learn WCF?

WCF is known for its flexibility. You can use it to build:

Secure services using encryption and authentication.

Reliable services that handle errors and resume communication.

Scalable services that grow as your application’s needs expand.

Getting Started

To begin, install the .NET framework, open Visual Studio, and create a new WCF service. Follow the built-in templates to get started quickly. Once you have your basic service, you can configure its endpoints, bindings, and contracts to customize the communication settings.

This WCF Tutorial for Beginners provides a solid foundation for building reliable and secure applications.

If you haven't been over to the Architecture section of the .NET site lately, I'd encourage you to go check it out. There is a TON of free learning content, books, code, and more!

Containers for Beginners

We've just put up a new Hello World tutorial for making your first microservice, and there's a video series on Docker and Containers as well. There are step-by-step instructions for installing .NET and building your first microservice using Docker. When you're done, follow how to deploy your microservice easily to Azure and Azure Kubernetes Service (AKS).

Intermediate - Cloud-native microservices

If you have about an hour, you can try out this new Learn Module for free - Create and deploy a cloud-native ASP.NET Core microservice. you can do it ALL in the browser with no software installation!

Imagine you're a software developer for an online retailer named eShopOnContainers. The retailer uses a cloud-native, microservices-based architecture developed using .NET Core for its online storefront. A new project is underway to add support for accepting coupon codes at checkout. Your assignment on the project is to finish writing a containerized ASP.NET Core web API to manage coupon codes—a web API that will be referred to as the coupon service.

This module explores completing the coupon service, adding it to the existing solution, and deploying it to the multi-container Kubernetes cluster.

Learning objectives

Examine existing ASP.NET Core microservices running in Azure Kubernetes Service (AKS).

Implement a new ASP.NET Core microservice and containerize it.

Overview of Power BI

Agenda

u What is Business Intelligence?

u BI Usage Examples

u Microsoft Power BI

u Power BI Architecture

u A look at the parts of Power BI:

u Power BI Desktop

u Power BI Service

u Power BI Mobile

u Power BI Embedded

u Power BI Video: Demo of some features, publishing & creating a dashboard

u Some useful DAX formulas

What is Business Intelligence?

u The term Business Intelligence (BI) refers to technologies, applications and practices for the collection, integration, analysis, and presentation of business information. The purpose of Business Intelligence is to support better business decision making.

u 1 Provide quality data

u 2 Gain deeper insight and facilitate better decision making

u 3 Align decisions with corporate goals

BI Usage Examples:

u Effect of decrease in price of 1.5 liter Pepsi on sale of 0.5 Liter Pepsi

Last year, Pepsi reduced price of 1.5 liter Pepsi. It impacted sale of 0.5 liter pepsi.

With the help of BI, Pepsi can decide whether it shall reduce price of 1.5 liter or not, was it beneficial last year or not ?

u Effect of introducing call and data packages by Telecom companies

They introduce various packages to increase their revenues on basis of analytics

Microsoft Power BI

u Power BI is a set of tools and technologies for business intellignence

u Power BI has data acquisition and transformation, data modelling and visualization tools. It is html 5, semi open source, app enabled and cloud enabled SaaS.

u Power BI is intended more to “power users” as well as developers. It can create dashboards with great presentation. It can be easier to create visualizations with correct data, but it might not be great if you want to print something. It’s basically the evolution of Powerpivot and Powerview.

u Free to use, works with unstructured data, user create their own reports by drag and drop of fields, minimal training required, modern rendering

u PowerBI data goes to the cloud but using DirectQuery is workaround for On Premises data.

Power BI Desktop

• Free download that starts your Power BI experience.

• Not an end user tool, but a power user and designer tool.

• Can be used to mash, model and design engaging experiences.

• Transform and clean data

• Design once and view anywhere

Power BI Service

• Cloud based service (Part of Office 365)

• Access to all data, wherver it may live

• Ask questions, integrate with cortana analytics and more

• Create curated content based on your company needs

• Share insights across web, mobile and embedded within your own applications.

Power BI Mobile

• Consume from almost any device

• Microsoft

• Android

• Apple – Including Apple Watch

• Set alerts that allow for proactive engagement

• Offline cache for dashboard consumption without an internet connection.

Power BI Embedded

• Ability to embed within any application or website.

• Includes Dynamics ERP and CRM

• Ability to deploy quickly with the scale of the Microsoft cloud.

Power BI Demo of some features, publishing & creating a dashboard

Youtube links of videos here, with video titles.

Some Useful DAX formulas

LookUp function : The following Lookup function is getting [Full Name] column from “User” entity where User[User Id] = opportunities[_ownerid_value]. This OwnerName column is being added in opportunities entity as calculated column.

OwnerName = LOOKUPVALUE (

User[Full Name],

User[User Id], opportunities[_ownerid_value]

)

Related() function: The following statement is getting column named [Full Name] from User table on basis of PrimaryKey-ForeignKey relationship of current entity with User entity. i.e. if this column OwnerName is being added in Sales entity, then it will pick User.[Full Name] on basis of Sales. UserID = User.UserID.

OwnerName = Related(User[Full Name])

Null Values: To avoid null value, add 0 to a calculation.

TotalContractualValue = CALCULATE (sum(opportunities[new_licensefee])) + 0

Usage of Format function for numeric data:

TotalContractualValue2 =

IF (

opportunity[TotalContractualValue] >= 1000000,

FORMAT ( opportunity[TotalContractualValue], “$#,##0,,.0m;($#,##0.0)m” ),

IF (

opportunity[TotalContractualValue] >= 1000,

FORMAT ( opportunity[TotalContractualValue], “#,##0,k” ),

FORMAT ( opportunity[TotalContractualValue], “General Number” )

)

Following are some sample formats.

“$#,##0.0;($#,##0.0)” >> >> show 16.7million (16700000) as 167,00,000.0

“$#,##0,,.0m;($#,##0.0)m” >> show 16.7million (16700000) as 16.7m

“#,##0,,m” >> show 16.7million (16700000) as 17m

Taking average days, on basis of dates difference:

AvgDays = averagex(leads, Datediff(leads[estimatedclosedate],leads[createdon],DAY) ) + 0

Taking average against a filter/where condition:

AvgDealAge = CALCULATE(

averagex(opportunities,Datediff(opportunities[createdon],today(),DAY) ) + 0,

FILTER(

opportunities,

opportunities[createdon] <= today()

)

Calculating Week number (i.e. week# in month):

WeekInMonthNo = FLOOR( Day( leads[createdon] ) / 7 ,1) + if( mod( day(leads[createdon]) , 7) =0, 0, 1)

Using switch statement in PowerBI: In following statement, if process[category]= 100000000 then it will return “A”

CategoryName = Switch( process[category],100000000,”A”,100000001,”B”,100000002,”C”)
