本示例演示如何使用适用于 .NET 的 Microsoft Agent Framework 构建智能旅行规划代理。该代理可以自动生成面向全球随机目的地的个性化一日游行程。

az login 登录# zsh/bash
export AZURE_OPENAI_ENDPOINT=https://<your-resource>.openai.azure.com
export AZURE_OPENAI_DEPLOYMENT=gpt-5-mini
# 然后登录以便 AzureCliCredential 能获取令牌
az login
# PowerShell
$env:AZURE_OPENAI_ENDPOINT = "https://<your-resource>.openai.azure.com"
$env:AZURE_OPENAI_DEPLOYMENT = "gpt-5-mini"
# 然后登录以便 AzureCliCredential 可以获取令牌
az login
运行代码示例，
# zsh/bash
chmod +x ./01-dotnet-agent-framework.cs
./01-dotnet-agent-framework.cs
或使用 dotnet CLI：
dotnet run ./01-dotnet-agent-framework.cs
