当我尝试使用Visual Studio中的IOS模拟器时,我遇到了麻烦.所以我使用xamarin(最新稳定版)在VS中创建了一个hello world应用程序,我将项目设置为主项目,当我用mac刷新连接时,我无法选择应该在selectList中显示的设备.消息是"没有连接设备":

如果我尝试在主机mac上使用xamarin工作室,一切都没问题,示例应用程序构建在iphone模拟器上:

我在MVC Controller中有一个SendMail方法.这个方法调用其他方法ValidateLogin.这是验证登录的签名:
private ActionResult ValidateLogin(Models.ResetPassword model)

当我从SendMail调用ValidateLogin时,出现此异常是因为控制器尝试搜索视图SendMail,但我想加载ResetPassword视图:

我想同时发送表单的文件和数据,所有映射到控制器的对象,但dropzone需要有"url"才能接受文件上传...如何解决这个问题?也许我可以获取表单元素的url并将其放入url参数?
我在同一个视图上有多个搜索栏:
barheures = (SeekBar)findViewById(R.id.barheures); // make seekbar object
barheures.setOnSeekBarChangeListener(this); // set seekbar listener.
// since we are using this class as the listener the class is "this"
barminutes = (SeekBar)findViewById(R.id.barminutes);
barminutes.setOnSeekBarChangeListener(this);

以下是列表:

Roslyn必须"重新构建"控制器然后如果我按f5我必须看到新内容不是吗?是否有激活该功能的选项?
我确定这是用于视图的视图包,因为当我停止并重新启动项目时,一切正常.
也许是因为roslyn没有被选为编译器,但是vNext需要roslyn才能运行sooo我很困扰:-)
