Developing ASP.NET Core App in Visual Studio and Deploying on Simple Application Server

Quick FAQ

What Is Visual Studio?

Developing Example Application


Alibaba Cloud account

Create ASP.NET core project from template

select File > New > Project
select ASP.NET Core Web Application as shown in image below

Edit and Change Code

This is where one would add their own development code. We are going to make a simple change.

Run Application

Press Ctrl+F5 (or Debug > Start Without Debugging). The app opens in a browser.

Publish Example Project for Deployment

With Visual Studio 2017, we can package our web application with all of the references needed to run on Linux by building a “Self-Contained Application”. This type of deployment does not require a .NET SDK to be installed on a server, and can be deployed to any machine that does not have any .NET features installed.

Prepare the Web Application

Unless your application uses Globalization rules and the data, it is better to go for globalization invariant mode. This ensures you do not need to install additional ICU ( packages on linux.

<RuntimeHostConfigurationOption Include="System.Globalization.Invariant" Value="true" />
app.UseForwardedHeaders(new ForwardedHeadersOptions
ForwardedHeaders = ForwardedHeaders.XForwardedFor | ForwardedHeaders.XForwardedProto
public static IWebHostBuilder CreateWebHostBuilder(string[] args) =>

Publish Project as Self-Contained Application

After debugging and testing the application, create the files to be deployed.

Publish from Visual Studio

Right click on Project name (not the solution) in Visual Studio Solution Explorer and select Publish.

Publish from Command Prompt

On development machine (in our case, our Windows machine), open a command prompt at the root of your web application (location where .csproj file exists) and run the following.

dotnet publish -c release -r linux-x64

Setup Server Configuration


Deploy application on simple application server

Create Password

Log back into console and select Simple Application Server

Install Prerequisites on Server


sudo yum -y update
sudo yum install nginx
sudo service nginx start
systemctl status nginx
sudo yum update
sudo yum install nano
sudo yum update
sudo yum install supervisor

Deploy Application

There are multiple ways of moving published application files to the server including the usage of FTP Client. We will use Filezilla. To install Filezilla for free visit

chmod +x alibabadotnetcore

Configure Nginx

Now, we configure NGINX to serve our .NET Core web application as a reverse proxy.

sudo cp /etc/nginx/nginx.conf /etc/nginx/nginx.conf.bak
sudo nano /etc/nginx/nginx.conf
location / {
proxy_pass http://localhost:5000;
proxy_http_version 1.1;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection keep-alive;
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
sudo nginx –t
sudo nginx -s reload
cd dotnetappdir/publish

Final Steps

Close the terminal and now refresh the browser window.

nginx error!

cp -r ~/dotnetappdir /var
touch /var/dotnetappdir/startscript
nano /var/dotnetappdir/startscript
cd /var/dotnetappdir/publish
chmod +x /var/dotnetappdir/startscript
nano /etc/supervisord.conf
sudo supervisord -c /etc/supervisord.conf


These are the basic steps one has to do to deploy an ASP.NET Core application after building the same on Visual Studio on Alibaba Cloud Simple Application Server with CentOS.
