RiderRS
扯淡：很多人说：jetbrains出品，必属精品，jetbrains确实出了不少好东西，但是他的产品总感觉越用越慢，我的小Y430P高配版也倍感压力，内存占用率高。
Multiple runtime support
Project Rider supports the .NET Framework and Mono, with CoreCLR support in the works. It also includes templates for creating new projects, and when you create an empty project, it's literally empty!
Build, run and debug
Project Rider can build MSBuild and XBuild solutions as well as DNX/.NET CLI projects, and allows debugging .NET and Mono applications. DNX/.NET CLI debugging and CoreCLR support are coming.
Cross platform
As well as running and debugging multiple runtimes, Project Rider itself runs on multiple platforms. It runs on Windows and Mac OS X (Linux support is on the way).
先附上下载地址，各大平台的：

楼主在Ubuntu 16.04上安装了Rider Version1.0 的版本，目前创建的项目有，.NET：Class Library、和Console Application 以及.NET Core：Class Library、Console Application，接下来附上截图。
1、下载：
2、解压安装
解压：sudo tar zxvf riderR5-163.3419.tar.gz
安装说明很详细
界面还是很美观的。
3、运行Rider：在解压后的bin目录下 输入 ./rider.sh 回车运行
谈下感受：界面很美观的，功能还是很强大，更何况是初版本，当然，IDE这个东西用起来顺手是最优的。像monodevelop 这个IDE也是很强大的，Linux下的编辑器:vim、sublime、Atom、VS Code...
只是为了尝鲜下，小伙伴们有兴趣的试试去吧。
VS宇宙级的IDE，真是无与伦比啊。哈哈
