Setting up dnx environment in your machine

If you are not a die hard fan of Visual Studio and regularly uses command prompt and text editors like Notepad or Sublime text for doing coding in C# and compilation, then there is a good news for you. You can make of the DNVM(.NET Version Manager) from ASP.NET Core from now. 

If you have Visual Studio in your machine, then you can skip the set up part and jump straight into the command sections. Becuase Visual Studion installs DNVM by default and no set up is needed.

Pre-requisites

  1. .NET version 4.5.2 or higher. If you don’t have it in your machine, install it from here. Need around 3 GB on your Windows drive, also admin access is needed for install. Don’t forget to reboot after the installation
  2. PowerShell version 4.0 or higher. Upgrade it here if you are running an older version. Admin access is needed for installation and also reboot is necessary once the installation is completed
  3. Install Visual C++ 2013 distributable package from here if it’s missing from your machine. Admin access is needed for this one also and you need to install both x86 and x64 versions

 

Let’s confirm now that we are having the required version of Powershell  by using the command below

$PSVersionTable.PSVersion

It should show 4 if you have upgraded using the link above. Basically the version should be 4 or higher.

So we have everything needed for the dnx environment to be installed in your box, so let’s type in the following command in the Command Prompt window to install it

@powershell -NoProfile -ExecutionPolicy unrestricted -Command “&{$Branch=’dev';iex ((new-object net.webclient).DownloadString(‘https://raw.githubusercontent.com/aspnet/Home/dev/dnvminstall.ps1′))}”

This will install the DNVM(.NET Version Manager) in to your user folder

You can verify the installation is happened correctly by typing the command

dnvm

 in PowerShell or Command Prompt. It will display a help information screen as shown below.

To view the list of the runtimes installed in your environment, use

dnvm list

To install the latest version of the runtimes

dnvm install latest

This will download the latest runtimes from the feeds and installs it to your user folder

For upgrading the dnvm and dnx use the following commands

dnvm update

dnvm upgrade -self

For restoring packages, use the following command 

dnu restore

dnu is a.NET utility which helps in restoring and building packages and compiling code too. 

If you type dnx command in the prompt, then it will display the help menu listing all the parameters available for the command as shown below.

  In the next post, I will show you how to configure the project and run it using dnx commands
