Deploying .NET 9 Applications via Plesk Print

Overview

This guide explains how to deploy your .NET 9 (ASP.NET Core 9) application to your Windows hosting account using Plesk. .NET 9 is fully supported on our Windows Server 2022 and 2019 hosting plans.

Deployment Options

1. Framework-Dependent Deployment (FDD) - Recommended

Uses the .NET 9 runtime installed on our servers. Smaller deployment size.

dotnet publish -c Release -o ./publish

2. Self-Contained Deployment (SCD)

Includes the .NET runtime with your application. Larger but independent.

dotnet publish -c Release -r win-x64 --self-contained true -o ./publish

Step 1: Publish Your Application

Using Visual Studio 2022:

1. Right-click your project → Publish
2. Select Folder as target
3. Click Show all settings
4. Configuration: Release
5. Target Framework: net9.0
6. Deployment Mode: Framework-dependent (recommended)
7. Target Runtime: win-x64
8. Click Publish

Using Command Line:

# Framework-dependent (smaller, uses server runtime)
dotnet publish -c Release -o ./publish

# Self-contained (larger, includes runtime)
