To recreate issue, on Win 10 or Server 2012 R2/2016 in Windows PowerShell 5.1, do the following:

Install-Module -Name UniversalDashboard.Community -AllowPrerelease
# NOTE: UniversalDashboard.Community is 2.0.0-beta2
Save-Module -Name UniversalDashboard.Sparklines -Path "$HOME\Documents\WindowsPowerShell\Modules"

# Remove the UniversalDashboard Module that is automatically downloaded since it is designated
# under RequiredModules in the UniversalDashboard.Sparklines Manifest
Remove-Item -Recurse "$HOME\Documents\WindowsPowerShell\Modules\UniversalDashboard" -Force

# Change Module Manifest RequiredModules from 'UniversalDashboard' to 'UniversalDashboard.Community'

$ManifestContent = Get-Content -Path $ManifestPath
$ManifestContent -replace 'RequiredModules = @\(.*?\)',
'RequiredModules = @("UniversalDashboard.Community")' | Set-Content -Path $ManifestPath

# Create the UD-Test function that copies the example in the ud-sparklines
Set-Content -Path "$HOME\Test-UD.ps1" -Value @'
function Test-UD {
    Param (
        [switch]$RemoveAllOtherUDDashboards = $True

    if ($RemoveAllOtherUDDashboards) {

            } | Out-UDTableData -Property @("Name", "Sparkline")

    Start-UDDashboard -Dashboard $MyDashboard

. "$HOME\Test-UD.ps1"

Import-Module UniversalDashboard.Community

Navigating to http://localhost/home only shows the UDTable headers and no content. No errors are displayed on the page.

Do I need the WebSockets Feature installed or something like that?

This is a problem with 2.0. I had the grand plan of changing how to make custom components. It's not going to make it into this release. I'm going to revert that code and get this working again.

@adamdriscoll adamdriscoll added this to the 2.0.0 milestone Aug 27, 2018

No worries! I'm trying to get fancy with some things, but it's by no means critical. I appreciate all the effort you're putting behind UD!
