Azure.Security.KeyVault.Secrets: az 未被识别为内部或外部命令

Question

我正在使用 .Net Core 开发 Web 应用程序并利用 Azure 服务（虚拟机 Windows Server 2016、数据库 PostgreSQL 和 Azure Key Vault）。下面是我的 .csproj 文件：

<Project Sdk="Microsoft.NET.Sdk.Web">

  <PropertyGroup>
    <TargetFramework>netcoreapp2.1</TargetFramework>
    <TypeScriptToolsVersion>3.1</TypeScriptToolsVersion>
    <UserSecretsId>.......................................</UserSecretsId>
    <Version>1.2.5.0</Version>
    <AssemblyVersion>1.2.5.0</AssemblyVersion>
    <FileVersion>1.2.5.0</FileVersion>
  </PropertyGroup>

  <PropertyGroup Condition="'$(Configuration)|$(Platform)'=='Release|AnyCPU'">
    <DebugType>none</DebugType>
    <DebugSymbols>false</DebugSymbols>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Azure.Identity" Version="1.3.0" />
    <PackageReference Include="Azure.Security.KeyVault.Secrets" Version="4.1.0" />
    <PackageReference Include="fo-dicom.NetCore" Version="4.0.7" />

    <PackageReference Include="Microsoft.Azure.Storage.Common" Version="9.4.2" />

    <PackageReference Include="Npgsql.Json.NET" Version="5.0.0" />
    <PackageReference Include="SharpZipLib" Version="1.3.1" />
  </ItemGroup>

</Project>

利用 Azure.Security.KeyVault.Secrets 库，我正在尝试检索存储在 Azure Key Vault 中的秘密，如下所示：

string keyVaultUri = $"https://{KeyVaultName}.vault.azure.net";
_secretClient = new SecretClient(new Uri(keyVaultUri), new DefaultAzureCredential());
KeyVaultSecret secret = _secretClient.GetSecret(secretName);

GetSecret 方法抛出以下异常：

我该如何解决这个问题？
