+**Fedora 42 DotNet Setup Checklist**
+
+**Important Preliminary Note:**
+*   [ ] **Fedora 42 Specifics:** Since Fedora 42 is a future release, always double-check the *exact* package names and commands against the official Fedora and Microsoft documentation once Fedora 42 is available. The commands below are based on current Fedora practices.
+
+---
+
+**I. Core .NET Development Environment**
+
+*   [ ] **Register Microsoft Package Repository:**
+    *   [ ] Import Microsoft GPG key (e.g., `sudo rpm --import https://packages.microsoft.com/keys/microsoft.asc`).
+    *   [ ] Add Microsoft package repository for Fedora 42 (e.g., `sudo wget https://packages.microsoft.com/config/fedora/42/packages-microsoft-prod.rpm -O packages-microsoft-prod.rpm` - *verify exact URL for F42*).
+    *   [ ] Install the downloaded repository configuration (e.g., `sudo dnf install -y packages-microsoft-prod.rpm`).
+    *   [ ] Clean up downloaded .rpm file (e.g., `rm packages-microsoft-prod.rpm`).
+*   [ ] **Install .NET SDK:**
+    *   [ ] Install the desired .NET SDK version (e.g., `sudo dnf install -y dotnet-sdk-8.0` or latest LTS).
+*   [ ] **Verify .NET Installation:**
+    *   [ ] Check SDK version: `dotnet --version`
+    *   [ ] List installed SDKs: `dotnet --list-sdks`
+    *   [ ] List installed runtimes: `dotnet --list-runtimes`
+
+---
+
+**II. Code Editor/IDE (Visual Studio Code Recommended)**
+
+*   [ ] **Install Visual Studio Code:**
+    *   [ ] Option A: From Fedora repositories (e.g., `sudo dnf install -y code`).
+    *   [ ] Option B: Download `.rpm` from [code.visualstudio.com](https://code.visualstudio.com/) and install (e.g., `sudo dnf install -y ./<vscode_downloaded_file>.rpm`).
+*   [ ] **Install Essential VS Code Extensions (Open VS Code to do this):**
+    *   [ ] **C# Dev Kit** (from Microsoft - this is key and bundles other C# tools).
+    *   [ ] (Optional but Recommended) NuGet Package Manager GUI.
+    *   [ ] (Optional but Recommended) GitLens.
+    *   [ ] (Optional but Recommended) Prettier - Code formatter.
+    *   [ ] (Optional) Any Blazor-specific snippet or tooling extensions you find useful.
+    *   [ ] *Restart VS Code if prompted after extension installations.*
+
+---
+
+**III. Version Control**
+
+*   [ ] **Install Git:**
+    *   [ ] `sudo dnf install -y git`
+*   [ ] **Configure Git (Global Settings):**
+    *   [ ] Set user name: `git config --global user.name "Your Name"`
+    *   [ ] Set user email: `git config --global user.email "youremail@example.com"`
+
+---
+
+**IV. Web Browser for Frontend Testing**
+
+*   [ ] **Install/Verify Modern Web Browser:**
+    *   [ ] Firefox (usually pre-installed on Fedora).
+    *   [ ] Or, install another like Chromium (e.g., `sudo dnf install -y chromium`) or Google Chrome.
+    *   [ ] *Familiarize yourself with its Developer Tools (Inspector, Console, Network).*
+
+---
+
+**V. Database (Optional - PostgreSQL Example)**
+
+*   [ ] **Install PostgreSQL Server & Contrib Packages:**
+    *   [ ] `sudo dnf install -y postgresql-server postgresql-contrib`
+*   [ ] **Initialize PostgreSQL Database Cluster:**
+    *   [ ] `sudo postgresql-setup --initdb`
+*   [ ] **Enable and Start PostgreSQL Service:**
+    *   [ ] `sudo systemctl enable --now postgresql`
+*   [ ] **Create PostgreSQL User and Database (via `psql`):**
+    *   [ ] Access `psql`: `sudo -u postgres psql`
+    *   [ ] Create user: `CREATE USER myappuser WITH PASSWORD 'yoursecurepassword';` (Replace with your details)
+    *   [ ] Create database: `CREATE DATABASE myappdb OWNER myappuser;` (Replace with your details)
+    *   [ ] Exit `psql`: `\q`
+*   [ ] **(Optional) Install PostgreSQL GUI Tool:**
+    *   [ ] e.g., pgAdmin 4: `sudo dnf install -y pgadmin4`

+    *   [ ] `sudo systemctl enable --now docker`
+*   [ ] **Add User to Docker Group:**
+    *   [ ] `sudo usermod -aG docker $USER`
+    *   [ ] **IMPORTANT: Log out and log back in for this group change to take effect.**
+*   [ ] **Install Docker Compose:**
+    *   [ ] `sudo dnf install -y docker-compose` (or check official Docker docs for other methods if needed).

+    *   [ ] `dotnet new blazorserver -o TestBlazorApp` (or `blazorwasm`)
+    *   [ ] `cd TestBlazorApp`
+    *   [ ] `dotnet run` (and check in browser)
