# Create WiX Setup

If you often ship software to customers, it might be comfortable for you to install it using setups rather than manually deploying.
FAKE provides you with support for creating MSI setups using the WiX Toolset (http://wixtoolset.org/).

## Minimal working example

Target "BuildWiXSetup" (fun _ ->
// This defines, which files should be collected when running bulkComponentCreation
let fileFilter = fun (file : FileInfo) ->
if file.Extension = ".dll" || file.Extension = ".exe" || file.Extension = ".config" then
true
else
false
// Collect Files which should be shipped. Pass directory with your deployment output for deployDir
let components = bulkComponentCreation fileFilter (DirectoryInfo deployDir)
// Collect component references for usage in features
let componentRefs = components |> Seq.map(fun comp -> comp.ToComponentRef())

let completeFeature = generateFeatureElement (fun f ->
{f with
Id = "Complete"
Title = "Complete Feature"
Level = 1
Description = "Installs all features"
Components = componentRefs
Display = Expand
})

// Generates a predefined WiX template with placeholders which will be replaced in "FillInWiXScript"
generateWiXScript "SetupTemplate.wxs"

let WiXUIMondo = generateUIRef (fun f ->
{f with
Id = "WixUI_Mondo"
})

let WiXUIError = generateUIRef (fun f ->
{f with
Id = "WixUI_ErrorProgressText"
})

let MajorUpgrade = generateMajorUpgradeVersion(
fun f ->
{f with
Schedule = MajorUpgradeSchedule.AfterInstallExecute
DowngradeErrorMessage = "A later version is already installed, exiting."
})

FillInWiXTemplate "" (fun f ->
{f with
// Guid which should be generated on every build
ProductCode = Guid.NewGuid()
ProductName = "Test Setup"
Description = "Description of Test Setup"
ProductLanguage = 1033
ProductVersion = "1.0.0"
ProductPublisher = "YouOrYourCompany"
// Set fixed upgrade guid, this should never change for this project!
UpgradeGuid = WixProductUpgradeGuid
MajorUpgrade = [MajorUpgrade]
UIRefs = [WiXUIMondo; WiXUIError]
ProgramFilesFolder = ProgramFiles32
Components = components
BuildNumber = "Build number"
Features = [completeFeature]
})

// run the WiX tools
WiX (fun p -> {p with ToolDirectory = WiXPath})
setupFileName
@".\SetupTemplate.wxs"
)

## Further possibilities
Besides just plainly shipping those files as setup you can also use the custom action and custom action execution elements to execute various commands before or after certain events during the installation.
This gives you the possibility to for example install, uninstall, start or stop certain services when you need to.
If your software is for example running as a service at your customer's side, you would need to manually stop and start the services on upgrades.
WiX knows the "ServiceControl" element for starting, stopping and removing services. You attach it to components.
If a component's files change and it has a Service Control element, the service that is referred to will be started, stopped or uninstalled, just as you defined it.
You can use the attachServiceToControlComponents function for attaching service controls to components. You would only have to slightly change the above example:

### Example
let serviceControl = generateServiceControl(fun f -> {f with
Id = "PickAnId"
Name = "QualifiedNameOfYourService"
Start = InstallUninstall.Install
Stop = InstallUninstall.Both
Remove = InstallUninstall.Uninstall})

// This defines, that all executable files should be tagged with the service control element
let componentSelector = fun (comp : WiXComponent) -> comp.Files |> Seq.exists(fun file -> file.Name.EndsWith(".exe"))

let components = attachServiceControlToComponents
(bulkComponentCreation (fun file ->
if file.Extension = ".dll" || file.Extension = ".exe" || file.Extension = ".config" then
true
else
false) (DirectoryInfo deployDir))
componentSelector
[serviceControl]
