+    .SYNOPSIS
+        This is a helper function that generates an objectname with the prefix WPF that can be used as a Powershell Variable after compilation.
+        To achieve this, all characters that are not a-z, A-Z or 0-9 are simply removed from the name.
+    .PARAMETER type
+        The type of object for which the name should be generated. (e.g. Label, Button, CheckBox...)
+    .PARAMETER name
+        The name or description to be used for the object. (invalid characters are removed)
+    .OUTPUTS
+        A string that can be used as a object/variable name in powershell.
+        For example: WPFLabelMicrosoftTools
+        
+    .EXAMPLE
+        Get-WPFObjectName -type Label -name "Microsoft Tools"
