+- Added Ansible.Basic C# util that contains a module wrapper and handles common functions like argument parsing and module return. This is gives the user more visibility over what the module has run and aligns PowerShell modules more closely to how Python modules are defined.

 When creating a new module there are a few things to keep in mind:
 
 - Module code is in Powershell (.ps1) files while the documentation is contained in Python (.py) files of the same name
-- Avoid using ``Write-Host/Debug/Verbose/Error`` in the module and add what needs to be returned to the ``$result`` variable
+- Avoid using ``Write-Host/Debug/Verbose/Error`` in the module and add what needs to be returned to the ``$module.Result`` variable
-- When trying an exception use ``Fail-Json -obj $result -message "exception message here"`` instead
+- To fail a module, call ``$module.FailJson("failure message here")``, an Exception or ErrorRecord can be set to the second argument for a more descriptive error message
 - Most new modules require check mode and integration tests before they are merged into the main Ansible codebase
 - Avoid using try/catch statements over a large code block, rather use them for individual calls so the error message can be more descriptive
 - Try and catch specific exceptions when using try/catch statements
 - Avoid using PSCustomObjects unless necessary
 - Look for common functions in ``./lib/ansible/module_utils/powershell/`` and use the code there instead of duplicating work. These can be imported by adding the line ``#Requires -Module *`` where * is the filename to import, and will be automatically included with the module code sent to the Windows target when run via Ansible
+- As well as PowerShell module utils, C# module utils are stored in ``./lib/ansible/module_utils/csharp/`` and are automatically imported in a module execution if the line ``#AnsibleRequires -CSharpUtil *`` is present
+- C# and PowerShell module utils achieve the same goal but C# allows a developer to implement low level tasks, such as calling the Win32 API, and can be faster in some cases
 - Ensure the code runs under Powershell v3 and higher on Windows Server 2008 and higher; if higher minimum Powershell or OS versions are required, ensure the documentation reflects this clearly
 - Ansible runs modules under strictmode version 2.0. Be sure to test with that enabled by putting ``Set-StrictMode -Version 2.0`` at the top of your dev script
 - Favour native Powershell cmdlets over executable calls if possible
-- If adding an object to ``$result``, ensure any trailing slashes are removed or escaped, as ``ConvertTo-Json`` will fail to convert it
 - Use the full cmdlet name instead of aliases, e.g. ``Remove-Item`` over ``rm``
 - Use named parameters with cmdlets, e.g. ``Remove-Item -Path C:\temp`` over ``Remove-Item C:\temp``

 A slightly more advanced module is `win_uri <https://github.com/ansible/ansible/blob/devel/lib/ansible/modules/windows/win_uri.ps1>`_ which additionally shows how to use different parameter types (bool, str, int, list, dict, path) and a selection of choices for parameters, how to fail a module and how to handle exceptions.
 
+As part of the new ``AnsibleModule`` wrapper, the input parameters are defined and validated based on an argument
+spec. The following options can be set at the root level of the argument spec:
+
+- ``mutually_exclusive``: A list of lists, where the inner list contains module options that cannot be set together
+- ``no_log``: Stops the module from emitting any logs to the Windows Event log
+- ``options``: A dictionary where the key is the module option and the value is the spec for that option
+- ``required``: Will fail when the module option is not set
+- ``required_if``: A list of lists where the inner list contains 3 or 4 elements;
+    * The first element is the module option to check the value against
+    * The second element is the value of the option specified by the first element, if matched then the required if check is run
+    * The third element is a list of required module options when the above is matched
+    * An optional fourth element is a boolean that states whether all module options in the third elements are required (default: ``$false``) or only one (``$true``)
+- ``required_one_of``: A list of lists, where the inner list contains module options where at least one must be set
+- ``required_together``: A list of lists, where the inner list contains module options that must be set together
+- ``supports_check_mode``: Whether the module supports check mode, by default this is ``$false``
+
+The actual input options for a module are set within the ``options`` value as a dictionary. The keys of this dictionary
+are the module option names while the values are the spec of that module option. Each spec can have the following
+options set:
+
+- ``aliases``: A list of aliases for the module option
+- ``choices``: A list of valid values for the module option, if ``type=list`` then each list value is validated against the choices and not the list itself
+- ``default``: The default value for the module option if not set
+- ``elements``: When ``type=list``, this sets the type of each list value, the values are the same as ``type``
+- ``no_log``: Will sanitise the input value before being returned in the ``module_invocation`` return value
+- ``removed_in_version``: States when a deprecated module option is to be removed, a warning is displayed to the end user if set
+- ``type``: The type of the module option, if not set then it defaults to ``str``. The valid types are;
+    * ``bool``: A boolean value
+    * ``dict``: A dictionary value, if the input is a JSON or key=value string then it is converted to dictionary
+    * ``float``: A float or `Single <https://docs.microsoft.com/en-us/dotnet/api/system.single?view=netframework-4.7.2>`_ value
+    * ``int``: An Int32 value
+    * ``json``: A string where the value is converted to a JSON string if the input is a dictionary
+    * ``list``: A list of values, ``elements=<type>`` can convert the individual list value types if set. If ``elements=dict`` then ``options`` is defined, the values will be validated against the argument spec. When the input is a string then the string is split by ``,`` and any whitespace is trimmed
+    * ``path``: A string where values likes ``%TEMP%`` are expanded based on environment values. If the input value starts with ``\\?\`` then no expansion is run
+    * ``raw``: No conversions occur on the value passed in by Ansible
+    * ``sid``: Will convert Windows security identifier values or Windows account names to a `SecurityIdentifier <https://docs.microsoft.com/en-us/dotnet/api/system.security.principal.securityidentifier?view=netframework-4.7.2>`_ value
+    * ``str``: The value is converted to a string
+
+When ``type=dict``, or ``type=list`` and ``elements=dict``, the following keys can also be set for that module option:
+
+- ``apply_defaults``: The value is based on the ``options`` spec defaults for that key if ``True`` and null if ``False``. Only valid when the module option is not defined by the user and ``type=dict``.
+- ``mutually_exclusive``: Same as the root level ``mutually_exclusive`` but validated against the values in the sub dict
+- ``options``: Same as the root level ``options`` but contains the valid options for the sub option
+- ``required_if``: Same as the root level ``required_if`` but validated against the values in the sub dict
+- ``required_one_of``: Same as the root level ``required_one_of`` but validated against the values in the sub dict
+
+A module type can also be a delegate function that converts the value to whatever is required by the module option. For
+example the following snippet shows how to create a custom type that creates a ``UInt64`` value:
+
+.. code-block:: powershell
+
+    $spec = @{
+        uint64_type = @{ type = [Func[[Object], [UInt64]]]{ [System.UInt64]::Parse($args[0]) } }
+    }
+    $uint64_type = $module.Params.uint64_type
+
 When in doubt, look at some of the other core modules and see how things have been
 implemented there.
