Installing DNVM
===============

You need DNVM as a starting point. DNVM enables you to acquire a (or multiple) .NET Execution Environment (DNX).
DNVM is simply a script, which doesn't depend on .NET. You can install it via a PowerShell command. 
You can find alternate DNVM install instructions at the [ASP.NET Home repo](https://github.com/aspnet/home).

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

You must close your command-prompt and start a new one in order for the user-wide environment variables to take effect.

You can see the currently installed DNX versions with `dnvm list`, which will display an empty set of installed runtimes.

	λ» dnvm list

Installing a .NET Core DNX
==========================

It's easy to install the latest .NET Core-based DNX, using the `dnvm install` command. The `-u` (or `-Unstable`) parameter installs latest unstable version.

	λ» dnvm install -r coreclr latest -u

This will install the 32-bit version of .NET Core. If you want the 64-bit version, you can specify processor architecture:

	λ» dnvm install -r coreclr -arch x64 latest -u

You can see the currently installed DNX versions with `dnvm list` (your display may vary as new versions of the DNX are published):

	λ» dnvm list

```
Active Version           Runtime Architecture Location                       Alias
------ -------           ------- ------------ --------                       -----
        1.0.0-beta7-12364 coreclr x86          C:\Users\rlander\.dnx\runtimes
        1.0.0-beta7-12364 coreclr x64          C:\Users\rlander\.dnx\runtimes
```

You can choose which of these DNXs you want to use with `dnvm use`, with similar arguments.

```
λ» dnvm use -r coreclr -arch x86 1.0.0-beta7-12364
Adding C:\Users\rlander\.dnx\runtimes\dnx-coreclr-win-x86.1.0.0-beta7-12364\bin
to process PATH

λ» dnvm list

Active Version           Runtime Architecture Location                       Alias
------ -------           ------- ------------ --------                       -----
   *    1.0.0-beta7-12364 coreclr x86          C:\Users\rlander\.dnx\runtimes
        1.0.0-beta7-12364 coreclr x64          C:\Users\rlander\.dnx\runtimes
```

This is an initial attempt to build fsharp.core for the coreclr:

Build FSharp.Core for .NET CoreCLR
==========================

fetch the DotNet buildtools using:
	λ» .nuget\NuGet.exe restore packages.config -PackagesDirectory packages

To build and pull in the corefx assemblies for nuget build coreclr using this command:


	λ» msbuild src\fsharp\FSharp.Core\FSharp.Core.fsproj /p:TargetFramework=coreclr /t:Rebuild /p:RestorePackages=true 


otherwise build fsharp.core like this:


	λ» msbuild src\fsharp\FSharp.Core\FSharp.Core.fsproj /p:TargetFramework=coreclr
