Project Setup and Hosting Mode in DotNet Core


ASP.NET Core is the framework that can be used for web development with .NET. If you have any experience with MVC or Web API over the last few years. Let's discuss how to create a new project in Visual Studio 2017.
To start with Dot net core project just add a new project from VS2017 and select empty project option.





Select application type as per your requirement here I am selecting empty application.











Your project is created and available in solution explorer and physical location as well.



























For me it’s available in F drive of my system. Here you will see few files which comes by default while creating a dotnet core application. These files are code files having default name Program and Startup.







Here one more default file (launchsettings.json) is created which have IIS settings and profile information of your application.


Dotnet core application have two type of hosting one is In-Process and second is OutProcess. These options can be configured from project configuration file which you can open from solution explorer by right click and select edit your project file as below.
Your application could be run through VS solution and command prompt as well. To run your application please use command dotnet run.







Output:












To check the project configuration file just right click on your project in solution explorer and click on editProjectFileName.config option. You will see the configuration file with few settings.






Once you open this file then one tag AspNetCoreHostingModel will be available there in the configuration file.





In-Process Hosting Mode
In this hosting mode application will be host inside the IIS worker process. There will be one web server. This approach also better in terms of application performance.













Out of Process Hosting Mode (Default Hosting)
In this hosting mode you will have two web server one is internal and second is external. Internal web server will be Kestrel and external web server could be IIS, apache, engine-ex which will be used as per the requirement.
Kestrel server by default configured with dotnet core setup. Which directly interact with internet or we can say internet facing web server.
Kestrel can be used with reverse proxy server for load balancing or scaling the application.












I hope you got the basic understanding to start with Dotnet core application with available application hosting options. I will explain more on dotnet core in my next article.

Happy Learning!!!

Operators in Asterisk with Linux

Operators When you create an Asterisk dialplan, you’re really writing code in a specialized scripting language. This means that the Asterisk dialplan—like any programming language—recognizes symbols called operators that allow you to manipulate variables. Let’s look at the types of operators that are available in Asterisk: Boolean operators These operators evaluate the “truth” of a statement. In computing terms, that essentially refers to whether the statement is something or nothing (non-zero or zero, true or false, on or off, and so on). The Boolean operators are: expr1 | expr2 This operator (called the “or” operator, or “pipe”) returns the evaluation of expr1 if it is true (neither an empty string nor zero). Otherwise, it returns the evaluation of expr2. expr1 & expr2 This operator (called “and”) returns the evaluation of expr1 if both expressions are true (i.e., neither expression evaluates to an empty string or zero). Otherwise, it returns zero. expr1 {=,
