MAC
第一步：从微软官网下载：https://www.visualstudio.com/vs/visual-studio-mac/
第二步：安装软件过程出现
It was not possible to complete an automatic installation. This might be due to a problem with your network, proxy servers or an unsolvable installation conflict. At this point, you can continue the installation by manually downloading and installing the independent pieces. The list below shows each component that you need to install.
Mono Framework
Download the Mono Framework v4.8.0 archive to any directory on your disk, double-click it and follow the instructions on screen. Please accept all the defaults during the installation, including the target drive.
Java SDK
Mac OS X uses its own version of Java and in order to install it you need to start the terminal app and type the following command:javac -versionAfter typing it you should see a Mac OS X system popup which will guide you to install the Java software.
Android SDK
Download the Android SDK for Mac OS X version 24.4.1, open the downloaded archive and copy the contents of the folder found at its root directory (most probably named android-sdk-macosx) to the /Users/cong/Library/Developer/Xamarin/android-sdk-macosx directory.
Click here in order to start the Android SDK Manager application. In the GUI make sure the following components are installed or selected for installation:
- Android SDK Tools
- Android SDK Platform-tools
- Android SDK Build-tools
- Android API 15
- Android API 19
- Android API 21
Once all the required components are selected (you can select others as well, if you wish) start the installation.If you cannot see /Users/cong/Library/Developer/Xamarin/android-sdk-macosx in Finder please click here to reveal the directory in Finder.
Download the Android NDK for Mac OS X version r10e, open the downloaded archive and copy the contents of its root directory (most probably named android-ndk-r10e) to the /Users/cong/Library/Developer/Xamarin/android-ndk directory.
When the Android SDK installation is finished you might want to start the Android Emulator Manager and create as many emulator images as you might need for your development. This step can be performed at any time, on an as-needed basis.
Visual Studio for Mac Preview
Download the Visual Studio for Mac Preview v7.0.0 archive to any directory on your disk, double-click it and then drag and drop the Visual Studio for Mac Preview icon to the Applications folder.
Xamarin.Android
Download the Xamarin.Android v7.1.0 archive to any directory on your disk, double-click it and follow the instructions on screen. Please accept all the defaults during the installation, including the target drive.
Xamarin.iOS
Download the Xamarin.iOS v10.4.0 archive to any directory on your disk, double-click it and follow the instructions on screen. Please accept all the defaults during the installation, including the target drive.
Xamarin.Mac
Download the Xamarin.Mac v3.0.0 archive to any directory on your disk, double-click it and follow the instructions on screen. Please accept all the defaults during the installation, including the target drive.
(这里没有用到移动端只需要下载：Mono Framework v4.8.0 archive Visual Studio for Mac Preview v7.0.0 archive 这2个包就可以，其他都是开发跨平台包）
三、激动人性时刻到来，打开vs，界面非常简洁，去除vs很多冗余功能，感觉舒服很多。。。。
四、新建一个mvc项目，会提示你要在线安装支持mvc类库，是从nuget下载dll？？
五 运行 微软66666
Windows
如果将上面代码放到windows系统，结果会怎么样呢？
环境：win10+vs2015 编译正常，运行也正常
上面那些只是小试牛刀，下面是见证奇迹时候，直接把之前项目【不连接数据库】丢到mac vs运行
居然报错，彻底把我惊呆了Operation is not supported on this platform. 这个操作不支持此平台。。。这个是预览版上bug？
对于出现问题，可以用以下几种方案
1:重启vs，重启电脑，卸载项目重新加载
2:so上面有人说是debug模式问题，我切换编译还是报错。
3:google一下说多了pdb文件，我清理一下整个解决方案，把所有bin目录删除，编译还是报错。。。
4:切换目标框架
会不会是Mono4.5没有全部移植过来类库？于是这个设置一下4.5.1 4.5.2，我在windows是net4.5，编译一下，依然报错。 我切换4.6.1一下编译 成功了。。。。
（然而我高兴太早了，准备想重现这个问题操作，备份一下csproj文件，还原之前旧版本csproj，然后一路报错下去解决不了，把正确csproj替换也不行）
5:mac上新建一个mvc项目，把代码拷贝过去（如果所有方法试过都不行，此方案是百试百灵，强烈推荐）
6:我旧项目对比一下5新建项目csproj，改了一摸一样也不行，fk
最后想说：vs在mac操作加入【未包括项目文件】很蛋疼。。
