Add custom format to Powershell SDK without using SnapIn

I am developing a .NET / C # 2.0 application that uses the PowerShell SDK to execute a script. I am not using SnapIns. I configure everything directly through PS RunspaceConfiguration.

So my problem is that I cannot add a custom format for my Plux.ExtensionTypeInfo type implemented in the application.

(Plux.ExtensionTypeInfo has a Name property)

Here's what I'm trying:

...
RunspaceConfiguration config = RunspaceConfiguration.Create();

config.Formats.Prepend(
    new FormatConfigurationEntry("plux.format.ps1xml")
    );

config.Formats.Update();
...

      

        
        
        
      

    

plux.format.ps1xml:

<Configuration>
  <ViewDefinitions>
  <View>
       <Name>Plux.ExtensionTypeInfo</Name>
            <ViewSelectedBy>
                <TypeName>Plux.ExtensionTypeInfo</TypeName>
            </ViewSelectedBy>
            <TableControl>
                <TableHeaders>
                    <TableColumnHeader>
                        <Width>30</Width>
                    </TableColumnHeader>
                </TableHeaders>
                <TableRowEntries>
                    <TableRowEntry>
                        <TableColumnItems>
                            <TableColumnItem>
                                <PropertyName>Name</PropertyName>
                            </TableColumnItem>
                        </TableColumnItems>
                    </TableRowEntry>
                </TableRowEntries>
            </TableControl>
        </View>
</ViewDefinitions>
</Configuration>

      

        
        
        
      

    

After running a cmdlet that returns multiple ExtensionTypeInfo objects, the output will never be formatted.

With built-in cmdlets and types, the formatting works fine in my PS Host app. Registering the Cmdlet also works fine through the config object. No error occurs when running update-formatdata on plux.format.ps1xml using powershell.exe or my hosting app.

However, the code above does not affect the formatting.
