C#模板，从数据库调用动态生成角色类

我正在尝试生成下面的角色类：

<#@ template debug="false" hostspecific="false" language="C#" #>
<#@ output extension=".cs" #>
<#@ assembly name="Microsoft.Extensions.Configuration"#>
<#@ import namespace="Microsoft.Extensions.Configuration" #>
namespace COMPANY.Application.Interfaces.Security
{
    public static partial class Role {
    <#
    var builder = new ConfigurationBuilder()
    .SetBasePath(Directory.GetCurrentDirectory())
    .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true)
    .AddEnvironmentVariables();
    var configuration = builder.Build();

    foreach (string nodeName in new string[]{"ADMIN", "GUEST", "TECH"}) {
    #>
    public const string <#= nodeName #> = nameof(<#= nodeName #>);
    <# } #>
}
}

除了单独查找所有这些依赖项之外，我不确定是否还有更简单的方法。 netstandard错误让我感到困惑，因为我已经有了对该SDK的引用
