我原本是使用NatashaInitializer.Initialize();
使用是正常的，但是我每次调用构建都要2秒的时间，感觉太费时间了。
所以就想到了InitializeAndPreheating();，可是我调用这个就报错。

Natasha版本：3.1.0.0
测试代码和错误信息如下：

测试代码:

using Microsoft.VisualStudio.TestTools.UnitTesting;
using System;
using Natasha.CSharp;
using System.Threading.Tasks;

namespace MyNameSpace
{
    [TestClass()]
    public class MyClassTest
    {
        [TestMethod()]
        public void Natasha_测试()
        {
            //仅仅注册组件 这个初始化是可以正常使用的，就是每次都要2秒左右，很耗费时间。
            NatashaInitializer.Initialize();
            for (int i = 0; i < 10; i++)
            {
                var start = DateTime.Now;
                Natasha测试一次();
                Console.WriteLine($"第{i}次查询用时:{(DateTime.Now - start).TotalSeconds}秒");
            }
        }
        [TestMethod()]
        public async Task Natasha_测试Async()
        {
            //注册+预热组件 , 之后编译会更加快速 可是这个调用报错了，想知道我应该怎么做
            await NatashaInitializer.InitializeAndPreheating();
            for (int i = 0; i < 10; i++)
            {
                var start = DateTime.Now;
                Natasha测试一次();
                Console.WriteLine($"第{i}次查询用时:{(DateTime.Now - start).TotalSeconds}秒");
            }
        }
        private void Natasha测试一次()
        {
            var newClassName = $"{nameof(BaseModel)}_{new Random().Next(int.MaxValue)}";
            var action = FastMethodOperator.DefaultDomain(option =>
            {
                option.Add($@"
                namespace MyNameSpace
                {{
                    public class {newClassName} : {nameof(BaseModel)}
                    {{
                        public override string Name => ""OveName"";
                    }}
                }}");
            })
            .Param(typeof(string), "inValue")
            .Body($@"
                var obj = new {newClassName}();
                return obj.Show(inValue);
                ")
            .Return<string>()
            .Compile<Func<string, string>>();
            var result = action("aaabbb");
            Console.WriteLine($"result:{result}");
        }
    }
    public class BaseModel
    {
        public virtual string Name => "BaseName";
        public string Show(string inValue)
        {
            Console.WriteLine($"ClassName:{this.GetType().Name},Name:{Name},InValue:{inValue}");
            return $"Result {inValue}";
        }
    }
}
