Deploy or Host ASP.NET Core web application in IIS

Dear folks,

Today I am going to explain the process of deploying the ASP.NET Core web application in IIS (Internet Information Services) web server.

Pre-requsites

• ASP.NET Core Runtime Hosting Bundle
• Navigate to https://dotnet.microsoft.com/download/dotnet-core/current/runtime
• Download Hosting Bundle to deploy [ASP].NET Core applications on a server

Application configuration

To make sure the application deploys and works with IIS, you should add the following while creating the web host.

WebHost.CreateDefaultBuilder(args)
                   .UseKestrel()
                   .UseIISIntegration()
                   .UseStartup();

 Where Kestrel hosts the application and IIS will be acting as a reverse proxy.

Publish the application

After doing the changes, publish the application to a folder as self-contained as you no need to bother about the server for all the application dependencies.

Web Configuration

• In Web.config, remove the following content
• hosting="In Progress"
• Copy files to IIS location
• Create a website folder in IIS wwwroot folder
• Copy the publish folder to the website folder
• Example: C:\inetpub\wwwroot\website

IIS Application Pool

• Create an application pool in IIS with following configuration
• Name:
• .NET CLR version: No Managed Code
• Managed pipeline mode: Integrated

Website Configuration

• Right click on the website and select "Add Application"
• Give the following details
• Alias:
• Application Pool: Select above created application pool from list
• Physical path: Select the above created website path
• Example: C:\inetpub\wwwroot\website

Restart IIS

• Once you have completed all the steps, perform the following to make sure everything is in sync.
• Open powershell in administrator mode
• Run the following commands
1. net stop was /y
2. net start w3svc

Test

Browse to the URL, you should be able to get the web pages.

• In BODY, create a DIV tag specifying the ID attribute and height and width style attributes
• id="mapid" style="width: 600px; height: 400px;"
• Get lat (Latitude) and long (Longitude) of your own choice of location.
• Take latlong reference from https://www.mapcoordinates.net/en
• Use map setView to set the location with latlong and zoom level
• var mymap = L.map('mapid').setView([17.496380,78.393175], 15);
• Make a marker with popup using marker and bindPopup functions
• var marker = L.marker([17.496380,78.393175]).addTo(mymap);

My first WebAssembly program

Hi folks,

Today, I am going to explain how to setup and write a sample program.

WebAssembly enables high performance applications on web pages. WebAssembly natively runs on browser along with HTML, CSS, JavaScript and approved by W3C (World Wide Web Consortium).

To know more about WebAssembly, go through the official webiste https://webassembly.org/

Pre-requisites

1. Git
2. CMake
3. Host system compiler
• Windows - Visual Studio 2017 +
• Linux - GCC
• Mac - XCode
4. Python 2.7.x

After downloading and installing the pre-requisites, make sure git, cmake and python are accessible in path.

Install

1. Open Terminal/PowerShell with Admin rights
2. Get the emsdk files

• git clone https://github.com/emscripten-core/emsdk.git

3. Navigate to the downloaded folder emsdk

• cd emsdk

4. Install (Note: On PowerShell execute this command, Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope LocalMachine)

• ./emsdk install latest

5. Activate

• ./emsdk activate latest

Create Sample HTML file

• Create folder
• mkdir hello
• Navigate to the folder
• cd hello
• Create a file hello.c and place the following code

#include
int main(int argc, char ** argv) { printf("Hello PSR!\n");}

Convert C file to HTML

emcc hello.c -o hello.html

Run WebServer (Optional)

Run emrun webserver to serve the html pages.

emrun --no_browser --port 8080 .

Hope, the tutorial is useful. Happy coding.

Go language install and configuration in Windows and Visual Studio Code as IDE

Hi folks,

Today I am going to describe you the best way to install and configure the Go language.

Download

From the Go language from its official web page https://golang.org/dl/

After installation, you would be able to program and run the code from any terminal.

What else?

Open your .go file in Visual Studio Code, it asks you something else. What was it?

"The "go-outline" command is not available. Run "go get -v github.com/ramya-rao-a/go-outline" to install."

What you need to do?

First, in Visual Studio Code set the the following in "settings.json" file.

"go.toolsGopath": "C:\\Go"

Note: If you are getting the following error, then click on "Install All"
The "go-outline" command is not available. Run "go get -v github.com/ramya-rao-a/go-outline" to install.

• Get the location, where it is installing
• Copy the bin and pkg folder contents to your Go installed folders.
• Delete the folder which VS Code used to download the content.

That's all.. you should be able to code in Visual Studio Code as well without having 2 different go installed folders.

Happy Go coding!!
