# Check Prerequisites for Dapr Workflow .NET

## Overview

This skill checks whether all prerequisites are installed for building Dapr Workflow applications in .NET. Run it only when you ask for it, for example before using the `create-workflow-dotnet` skill. It is never run automatically as a pre-step.

## Prerequisites

The following must be installed:

- [.NET 10 SDK](https://dotnet.microsoft.com/en-us/download)
- [C# LSP Plugin](https://claude.com/plugins/csharp-lsp)
- [Docker](https://www.docker.com/products/docker-desktop/) or [Podman](https://podman.io/docs/installation)
- [Dapr CLI](https://docs.dapr.io/getting-started/install-dapr-cli/) (version 1.18+)

## Prerequisite Checks

**Run ALL of these checks. Check steps 2-5 in parallel. Track which checks pass and which fail.**

### Step 1: Detect Operating System

Read the file at [`../dapr-shared/prereq-detect-os.md`](../dapr-shared/prereq-detect-os.md) and follow those instructions.

### Step 2: Check the C# LSP plugin

Read the file at [`../dapr-shared/prereq-check-csharp-lsp.md`](../dapr-shared/prereq-check-csharp-lsp.md) and follow those instructions.

### Step 3: Check .NET SDK

Read the file at [`../dapr-shared/prereq-check-dotnet-sdk.md`](../dapr-shared/prereq-check-dotnet-sdk.md) and follow those instructions.

### Step 4: Check Docker or Podman

Read the file at [`../dapr-shared/prereq-check-docker-podman.md`](../dapr-shared/prereq-check-docker-podman.md) and follow those instructions.

### Step 5: Check Dapr CLI

Read the file at [`../dapr-shared/prereq-check-dapr-cli.md`](../dapr-shared/prereq-check-dapr-cli.md) and follow those instructions.

## Show final message

After all checks are complete, report the results:

- List each check and whether it passed or failed.
- For any failed checks, provide the relevant install link from the Prerequisites section.
- If all checks passed, inform the user they can proceed with the `create-workflow-dotnet` skill.
