.NET Core 1.0 正式发布了，所以尝尝鲜。
根据官方（https://www.microsoft.com/net/core#ubuntu）介绍页面的步骤：
步骤1.
sudo sh -c 'echo "deb [arch=amd64] https://apt-mo.trafficmanager.net/repos/dotnet/ trusty main" > /etc/apt/sources.list.d/dotnetdev.list'
sudo apt-key adv --keyserver apt-mo.trafficmanager.net --recv-keys 417A0893
sudo apt-get update
步骤2.
sudo apt-get install dotnet-dev-1.0.0-preview2-003121
步骤3.
mkdir hwapp
cd hwapp
dotnet new
步骤4.
dotnet restore
dotnet run
结果出了不少问题：
问题1，由于网络原因，资源下载不下来——只能反复尝试。
问题2，执行dotnet run 时报错：
The specified framework 'Microsoft.NETCore.App', version '1.0.0-rc2-3002702' was not found.
- Check application dependencies and target a framework version installed at:
/usr/share/dotnet/shared/Microsoft.NETCore.App
- The following versions are installed:
1.0.0
- Alternatively, install the framework version '1.0.0-rc2-3002702'.
SUMMARY: Total: 1 targets, Passed: 0, Failed: 1.
问题2解决方法：
在步骤2后面，执行如下命令：
apt-get install dotnet-sharedframework-microsoft.netcore.app-1.0.0-rc2-3002702
解决上面问题后，再执行：dotnet run
结果如下图：
