I have installed Visual Studio 2015 Update 1. However despite selecting install Web Applications it wasn't installed. I then installed from the get.asp.net website the installer asp.net 5 RC.

Now when I want to open my ASP.net 5 project I get this message:

enter image description here

How do I know which one is the latest version? dnx-clr-win-x86.1.0,0,rc1-final and dnx-clr-win-x86.1.0,0.rc1-update1

and how do I upgrade my existing project to use the latest one.

The latest version is the update-1. There was not a lot of communication about it, but you can safely upgrade your projects to it, you don't need rc1-final anymore, unless you specifically want it.

The easiest way to do this is simply right-click on your project, Properties and selecting which dnx version you want to use. Clicking No should also have this effect.

rc1-update1 was released a couple of weeks after rc1, due to some installer/dnx issues. An update was appended to the official rc1 release announcement.

The ASP.NET 5 RC1 installers and DNX packages have been updated to address the following issues:

  • If you run the Windows installer from a folder that contains previous versions of the MSI installers for DNVM (DotNetVersionManager-x64.msi or DotNetVersionManager-x86.msi) or the ASP.NET tools for Visual Studio (WebToolsExtensionsVS14.msi or WebToolsExtensionsVWD14.msi), the installer will fail with an error “0x80091007 - The hash value is not correct”.
  • When installing on OS X the .pkg installer would create the ~/.dnx folder on a clean machine as root so you couldn’t do anything involving that folder unless you were root (aspnet/dnx#3191)
  • Running a published .NET Core based application results in FileNotFoundExceptions for missing assemblies (ex. System.Net.Security, System.Data.SqlClient) (aspnet/dnx#3183)

The updated version of DNX (1.0.0-rc1-update1) is available via the .NET Version Manager (DNVM). Note, no other ASP.NET 5 NuGet packages are affected by this update and thus their versions remain unchanged. If you have already installed RC1 please acquire and run the installer again from http://get.asp.net to get this update.
