.NET

Overview

.NET is a platform for building applications using C#, F#, and Visual Basic. It uses NuGet as its package manager for sharing and consuming reusable code packages.

Integrating .NET with JFrog Fly allows you to manage your packages and releases from source code to production in a simple and native way, directly from your IDE.

Supported Clients

JFrog Fly supports .NET packages with:

dotnet CLI (dotnet nuget push, dotnet restore) - The modern .NET command-line interface
NuGet CLI (nuget push, nuget restore) - The standalone NuGet command-line tool

Upload / Push Package

With Fly App

Activate .NET in your Fly App to configure .NET globally with Fly. The Fly App sets the Fly registry as the default push source, so you can push without specifying --source:

Using dotnet CLI:

dotnet nuget push <package>.nupkg

Using NuGet CLI:

nuget push <package>.nupkg

Manual Configuration

1. Generate an access token in Fly Token Management

2. Configure .NET:

Using dotnet CLI:

dotnet nuget add source https://<your-fly-subdomain>.jfrog.io/artifactory/api/nuget/nuget \
  --name Fly \
  --username <your-fly-username> \
  --password <your-fly-token> \
  --store-password-in-clear-text

Using NuGet CLI:

nuget sources add -Name Fly \
  -Source https://<your-fly-subdomain>.jfrog.io/artifactory/api/nuget/nuget \
  -Username <your-fly-username> \
  -Password <your-fly-token>

3. Push package:

Using dotnet CLI:

dotnet nuget push <package>.nupkg --source Fly

Using NuGet CLI:

nuget push <package>.nupkg -Source Fly

Download / Restore Package

With Fly App

Activate .NET in your Fly App to configure .NET globally with Fly, then restore as usual:

Using dotnet CLI:

dotnet restore

Using NuGet CLI:

nuget restore

Manual Configuration

1. Generate an access token in Fly Token Management

2. Configure .NET:

Using dotnet CLI:

dotnet nuget add source https://<your-fly-subdomain>.jfrog.io/artifactory/api/nuget/nuget \
  --name Fly \
  --username <your-fly-username> \
  --password <your-fly-token> \
  --store-password-in-clear-text

Using NuGet CLI:

nuget sources add -Name Fly \
  -Source https://<your-fly-subdomain>.jfrog.io/artifactory/api/nuget/nuget \
  -Username <your-fly-username> \
  -Password <your-fly-token>

3. Restore packages:

Using dotnet CLI:

dotnet restore

Using NuGet CLI:

nuget restore

From Public Registry

When you restore a package that isn’t in your Fly Registry, JFrog Fly automatically fetches it from nuget.org and caches it for future use.

Using dotnet CLI:

dotnet restore

Using NuGet CLI:

nuget restore

Upload/Download Packages with CI

To push and restore .NET packages with CI, update your GitHub Actions workflow to include the Fly action.

Simply type in your IDE the prompt: “Configure my workflows with Fly” and Fly MCP will configure your GitHub Actions workflow yml file, as follows:

1. Add permissions (top level, after on:):

permissions:
  contents: read
  id-token: write

2. Add Fly Action (after actions/setup-dotnet, before dotnet/nuget commands):

- name: JFrog Fly - Configure all your package managers to work with Fly registry
  uses: jfrog/fly-action@v1
  with:
    url: https://<your-fly-subdomain>.jfrog.io

GitHub Action Example

name: Build and Publish .NET Package

on:
  push:
    branches: [main]

permissions:
  contents: read
  id-token: write

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout code
        uses: actions/checkout@v4

      - name: Setup .NET
        uses: actions/setup-dotnet@v4
        with:
          dotnet-version: '8.0'

      - name: JFrog Fly - Configure all your package managers to work with Fly registry
        uses: jfrog/fly-action@v1
        with:
          url: https://<your-fly-subdomain>.jfrog.io

      - name: Restore dependencies
        run: dotnet restore

      - name: Build
        run: dotnet build --configuration Release

      - name: Pack
        run: dotnet pack --configuration Release

      - name: Push package
        run: dotnet nuget push ./bin/Release/*.nupkg
