.NET Portability Analyzer Website

This repository contains the source code for the .NET Portability website.

Today, the repository contains the following components:

  • DotNetStatus. An ASP.NET 5 implementation of .NET Portability site.

Using this Repository

  1. Install the following:
    1. Visual Studio 2015
    2. .NET Version Manager (DNVM)
    3. .NET Execution Environment (DNX)


Building/Running from Commandline

  1. Go to src\DotNetStatus
  2. Run command: dnu restore
  3. Run command: dnx . web
  4. The website should be started on http://localhost:5000

Building/Running from Visual Studio

  1. Open DotNetStatus.sln

  2. Check that all the Dependencies have loaded (like NPM and Bower) and packages were restored

    • Check the Output window -> Package Manager Log to make sure that everything was successful
  3. There are two targets you can run/debug with:

    • IIS Express
    • web - To run on DNX

    These can be found under the Project Properties -> Debug or by clicking the drop-down menu on the Debug button in your main toolbar.

  4. You can also change the Target DNX Version (ex. so that it runs on .NET Core) by:

    • Go to Project Properties -> Application
    • Check off "Use specific DNX version"
    • Change the Platform from .NET Framework to .NET Core


  1. dnu restore outputs: Error: ENOENT, stat 'C:\Users\CurrentUser\AppData\Roaming\npm'
    • Execute: mkdir %APPDATA%\npm (Command Prompt) or mkdir $env:AppData\npm (Powershell)
    • Execute: dnu restore
  2. dnu restore outputs: 'grunt' is not recognized as an internal or external command
    • Execute: npm install -g grunt-cli
    • Execute: dnu restore


Building/Running on Ubuntu

  1. Go to src/DotNetStatus
  2. Install npm
    • sudo apt-get update
    • sudo apt-get install nodejs
    • sudo apt-get install npm
  3. Install Grunt globally
    • sudo npm install -g grunt-cli
  4. dnu restore
  5. cd src/DotNetStatus
  6. grunt
  7. Run the site: dnx . kestrel


  1. dnu restore cannot find Microsoft.Fx.Portability
    • Open ~/.config/NuGet/NuGet.config in a text editor
    • Add <add key="dotnet-apiport" value="" /> under <packageSources>
    • Try again
