composer.json:

"require": {
    ...
    "illuminate/html"	: "~5.0",

app.php:

'providers' => [
    ...
    'Illuminate\Html\HtmlServiceProvider',
],

'aliases' => [
    ...
    'HTML'      => 'Illuminate\Html\HtmlFacade',
    'Form'      => 'Illuminate\Html\FormFacade',
],

Thanks, That got me past the problem with the Form not being found but when the View is rendered the html is encoded so that the page is shown as

Another View ! e<form method="POST" action="http://laravel5-demo/foo/bar" accept-charset="UTF-8"><input name="_token" type="hidden" value="vgh3GyU5BWLXDRdhBC7L864nkdQi2VTU1LR3Wcht"> <input name="associationId" type="text"> <label for="name" class="control-label col-lg-3">Name:</label> <input name="name" type="text" id="name">

Doing a view source on page shows:

				Another View !

<form method="POST" action="http://laravel5-demo/foo/bar" accept-charset="UTF-8"><input name="_token" type="hidden" value="vgh3GyU5BWLXDRdhBC7L864nkdQi2VTU1LR3Wcht">

	<div class="col-lg-9">
		&lt;input name=&quot;associationId&quot; type=&quot;text&quot;&gt;<br>

</div>
<div class="form-group">

	<div class="col-lg-9">

				</div>
 </div>

</form>
