对于我的学校项目，我正在使用 MVC 项目附带的默认帐户 Controller 注册函数:

// POST: /Account/Register
[HttpPost]
[AllowAnonymous]
[ValidateAntiForgeryToken]
public async Task<ActionResult> Register(RegisterViewModel model){
    if (ModelState.IsValid){
        var user = new ApplicationUser(){UserName = model.UserName};
        var result = await UserManager.CreateAsync(user, model.Password);
        if (result.Succeeded){
            await SignInAsync(user, isPersistent: false);
            return RedirectToAction("Index", "Home");
        }
        else{
            AddErrors(result);
        }
    }

    // If we got this far, something failed, redisplay form
    return View(model);
}

但是当我单击表单中的注册按钮时，我得到:覆盖方法的安全可访问性必须与被覆盖方法的安全可访问性相匹配

我搜索了一下，发现添加 [SecurityCritical] 应该可以解决这个问题，但您不能将其添加到异步任务中。

还发现添加 [assembly: SecurityRules(SecurityRuleSet.Level1)] 应该可以，但也行不通

这仅在我的发布服务器上(运行集成管道的 4.0 版)

最佳答案

仅当在 GAC 下注册时，程序集才会获得完全信任.如果您的程序集是私有(private)程序集，则它是部分信任和透明的 ( example of transparent behavior )。由于您的程序集是一个私有(private) 程序集，Dot Net CLR 将忽略[SecurityCritical]。

因此，如果您计划继续保持 private 程序集并以中等信任度运行它，则您不能覆盖或访问 [SecurityCritical] 成员。
