程序集重复引用 % 错误CS0246
我想在Unity项目中创建单元测试，但总是遇到两类问题中的一种（甚至两者都遇到）：
- 程序集存在重复引用
- 错误CS0246：类型或命名空间名称 '...' 无法找到（是否缺少using指令或程序集引用？）
如何同时修复这两个问题？
- 框架：Unity测试框架
- Unity项目结构：

解决方案
你不能随意把脚本放在顶层文件夹里，不把它们放进命名空间，也不把它们与测试关联起来就指望一切都会顺利。
如果你创建了一个Scripts文件夹，把脚本放进去，并创建一个名为Game.Scripts的 asmdef，然后在测试中引用它，编译就没问题。
-- MyScripts.asmdef
{
"name": "MyScripts",
}
-- 为避免混淆，下面的内容是在上述基础上修改后的版本，展示了包含所需类的MyScripts的引入。
-- PlayMode.asmdef
{
"name": "Game.PlayModeTests",
"references": [
"UnityEngine.TestRunner",
"UnityEngine.TestRunner.NUnit",
"Assembly-CSharp",
"MyScripts"
],
"testAssembly": true
}
--EditMode.asmdef
{
"name": "Game.EditModeTests",
"references": [
"UnityEngine.TestRunner",
"UnityEngine.TestRunner.NUnit",
"Assembly-CSharp-Editor",
"MyScripts"
],
"includePlatforms": [

}
