Steps to get ASP.NET 5 on Ubuntu

  • Install DNVM
  • Install DNX
  • Install Libuv
  • Install git
  • Download ASP.NET Sample
  • Run dnx web

Installing .NET Version Manager(DNVM)

  • Install and unzip curl if you have not installed:

 sudo apt-get install unzip curl
  • Download and install DNVM:

 curl -sSL https://raw.githubusercontent.com/aspnet/Home/dev/dnvminstall.sh | DNX_BRANCH=dev sh && source  ~/.dnx/dnvm/dnvm.sh

 Once you run above command you should be able to run dnvm commands like “dnvm list”.

Installing .NET Execution Environment (DNX) for .NET Core

  • Install DNX Pre-requisites:

 sudo apt-get install libunwind8 gettext libssl-dev libcurl4-openssl-dev zlib1g libicu-dev uuid-dev
  • Install DNX for .NET Core using DNVM:

 dnvm upgrade -r coreclr

 

Installing Libuv

Libuv is a multi-platform asynchronous IO library that is used by Kestrel, a cross-platform HTTP server for hosting ASP.NET 5 web applications.

To build Libuv run the below commands one after the other:

 sudo apt-get install make automake libtool curl

 curl -sSL https://github.com/libuv/libuv/archive/v1.4.2.tar.gz | sudo tar zxfv - -C /usr/local/src

 cd /usr/local/src/libuv-1.4.2

 sudo sh autogen.sh

 sudo ./configure

 sudo make

 sudo make install

 sudo rm -rf /usr/local/src/libuv-1.4.2 && cd ~/

 sudo ldconfig

Make sure libuv.so.1 is there under /usr/local/lib after you run above commands.

For now, we have .NET core setup and below steps will help you to download sample ASP.NET 5 application from Git

 

Install Git

Run below command to install git:

 sudo apt-get install git

 

Download ASP.NET 5 Sample from Git

Run the below command to clone ASP.NET 5 application from git:

 sudo git clone https://github.com/aspnet/Home.git

Run DNX Command

Navigate to the directory where the application is installed and in my above example it would have installed 3 applications “ConsoleApp”, “HelloMvc” and “HelloWeb”.

Run below command to execute the “ConsoleApp” application:

 dnu restore

 

 dnx run

 

Note: In case you run into an issue where you get error as:

 Restore failed

 Access to the path ‘/home/<user>/Home/Sample/…/ConsoleApp/project.locl.json’ is denied.

when you run “dnu restore” command then you need to check the permission on the application directory level. In my case I ran into this issue and ran below command at application directory level to give full permission.

 sudo chmod 777 <foldername>

    Using Ubuntu 15.10: I got down to dnx run at the command prompt and this appeared to do nothing. There was no success and no error. Was in the wrong folder when I tried this? I tried several in the samples.

    Have the same issue. No errors, no messages after "dnu restore"and "dnx run" ... really confusing. Any ideas?

    It seems like Ubuntu 15.10 is not compatible. Found a workaround wget security.ubuntu.com/.../libicu52_52.1-8ubuntu0.2_amd64.deb sudo dpkg -i libicu52_52.1-8ubuntu0.2_amd64.deb
