# fsharp-dnx-templates
Visual Studio templates for creating DNX projects with F#.

## Getting started
Right now we have the following templates:
* [Class library](https://github.com/fsprojects/fsharp-dnx-templates/tree/master/src/ClassLibrary)
* [Console app](https://github.com/fsprojects/fsharp-dnx-templates/tree/master/src/ConsoleApp)
* [Empty web app](https://github.com/fsprojects/fsharp-dnx-templates/tree/master/src/EmptyWeb)

The installation approach is identical for each template.
* The content template (e.g. [FSharpConsoleApp](https://github.com/fsprojects/fsharp-dnx-templates/tree/master/src/ConsoleApp/FSharpConsoleApp)) goes into `..\Microsoft Visual Studio 14.0\Common7\IDE\AspNetProjectTemplates\1033\`
* The DNX template (e.g. [FSharpDNXConsoleApp](https://github.com/jbfp/fsharp-dnx-templates/tree/master/src/ConsoleApp/FSharpDNXConsoleApp)) goes into `..\Microsoft Visual Studio 14.0\Common7\IDE\ProjectTemplates\FSharp\1033`

To get Visual Studio to register the templates, you can run `devenv.exe /installvstemplates`. (`devenv.exe` is in the `..\Microsoft Visual Studio 14.0\Common7\IDE\` folder.)

## FAQ
### Where can I find the `FSharp.Dnx` dependency?
The `FSharp.Dnx` dependency can be found in the fsprojects NuGet feed: https://www.myget.org/F/fsprojects/api/v3/index.json
You can include it in your NuGet.Config file:
```xml
<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    
    <clear />
    <add key="fsprojects" value="https://www.myget.org/F/fsprojects/api/v3/index.json" />
    <add key="api.nuget.org" value="https://api.nuget.org/v3/index.json" />
  </packageSources>
</configuration>
```

If you don't have a NuGet.config file, create it yourself in the solution root. You can then add it to Visual Studio by right-clicking the solution node in the Solution Explorer and adding an existing item.

### Why does an EmptyWeb application return `500 Internal Server Error` when running it? I haven't changed a thing!
Because you need a newer version of `Microsoft.AspNet.IISPlatformHandler` which you can get by adding [the ASP.NET "dev" build NuGet feed](https://www.myget.org/F/aspnetvnext/api/v3/index.json) to your NuGet.Config.

### Why is the `Program` type a class with a `Main` method and not a simple F# function like the standard F# Console Application template?
When DNX loads, [it looks for a class called `Program` with a method called `Main`](https://github.com/aspnet/dnx/blob/7ac7929aa575e17b3c271e4a7a0c164418de0395/src/Microsoft.Dnx.Runtime.Sources/Impl/EntryPointExecutor.cs#L70-L111).
You can do
```F#
namespace ConsoleApplication1

type Program () =
    member x.Main (argv: string array) =
        printfn "%A" argv
        0
```
but you can also do
```F#
module MyModule

type Program () =
    member x.Main (argv: string array) =
        printfn "%A" argv
        0
```
or
```F#
module Program

let Main (argv: string array) =
    printfn "%A" argv
    0
```
If you choose to use a Program class, you can do dependency injection, e.g. inject an `IApplicationEnvironment`.
