+        Every section belongs to one section group.
+        A section group is a container of logically-related sections.

+      The <configSections> section controls the registration of sections.
+      Section is the basic unit of deployment, locking, searching and
+      containment for configuration settings.
+
+      Every section belongs to one section group.
+      A section group is a container of logically-related sections.
+
+      Sections cannot be nested.
+      Section groups may be nested.

+/*++
+
+Abstract:
+
+    Main Handler for websocket requests.
+
+    Initiates websocket connection to backend.
+    Uses WinHttp API's for backend connections,
+    and IIS Websocket API's for sending/receiving
+    websocket traffic.
+
+    Transfers data between the two IO endpoints.
+
+-----------------
+Read Loop Design
+-----------------
+When a read IO completes successfully on any endpoints, Asp.Net Core Module doesn't
+immediately issue the next read. The next read is initiated only after
+the read data is sent to the other endpoint. As soon as this send completes,
+we initiate the next IO. It should be noted that the send complete merely
+indicates the API completion from HTTP, and not necessarily over the network.
+
+This prevents the need for data buffering at the Asp.Net Core Module level.

+/*++
+  class MULTISZ:
+
+  Intention:
+    A light-weight multi-string class supporting encapsulated string class.
+
+    This object is derived from BUFFER class.
+    It maintains following state:
+
+     m_fValid  - whether this object is valid -
+        used only by MULTISZ() init functions
+        * NYI: I need to kill this someday *
+     m_cchLen - string length cached when we update the string.
+     m_cStrings - number of strings.
+
+  Member Functions:
+    There are two categories of functions:
+      1) Safe Functions - which do integrity checking of state
+      2) UnSafe Functions - which do not do integrity checking, but
+                     enable writing to the data stream freely.
+             (someday this will be enabled as Safe versions without
+               problem for users)

+  class MULTISZ:
+
+  Intention:
+    A light-weight multi-string class supporting encapsulated string class.
+
+    This object is derived from BUFFER class.
+    It maintains following state:
+
+     m_fValid  - whether this object is valid -
+        used only by MULTISZ() init functions
+        * NYI: I need to kill this someday *
+     m_cchLen - string length cached when we update the string.
+     m_cStrings - number of strings.
+
+  Member Functions:
+    There are two categories of functions:
+      1) Safe Functions - which do integrity checking of state
+      2) UnSafe Functions - which do not do integrity checking, but
+                     enable writing to the data stream freely.

+/*++
+  class MULTISZ:
+
+  Intention:
+    A light-weight multi-string class supporting encapsulated string class.
+
+    This object is derived from BUFFER class.
+    It maintains following state:
+
+     m_fValid  - whether this object is valid -
+        used only by MULTISZ() init functions
+        * NYI: I need to kill this someday *
+     m_cchLen - string length cached when we update the string.
+     m_cStrings - number of strings.
+
+  Member Functions:
+    There are two categories of functions:
+      1) Safe Functions - which do integrity checking of state
+      2) UnSafe Functions - which do not do integrity checking, but
+                     enable writing to the data stream freely.
+             (someday this will be enabled as Safe versions without
+               problem for users)

+/*++
+  class MULTISZ:
+
+  Intention:
+    A light-weight multi-string class supporting encapsulated string class.
+
+    This object is derived from BUFFER class.
+    It maintains following state:
+
+     m_fValid  - whether this object is valid -
+        used only by MULTISZ() init functions
+        * NYI: I need to kill this someday *
+     m_cchLen - string length cached when we update the string.
+     m_cStrings - number of strings.
+
+  Member Functions:
+    There are two categories of functions:
+      1) Safe Functions - which do integrity checking of state
+      2) UnSafe Functions - which do not do integrity checking, but
+                     enable writing to the data stream freely.
+             (someday this will be enabled as Safe versions without
+               problem for users)

+/*++
+
+Abstract:
+
+    Main Handler for websocket requests.
+
+    Initiates websocket connection to backend.
+    Uses WinHttp API's for backend connections,
+    and IIS Websocket API's for sending/receiving
+    websocket traffic.
+
+    Transfers data between the two IO endpoints.
+
+-----------------
+Read Loop Design
+-----------------
+When a read IO completes successfully on any endpoints, Asp.Net Core Module doesn't
+immediately issue the next read. The next read is initiated only after
+the read data is sent to the other endpoint. As soon as this send completes,
+we initiate the next IO. It should be noted that the send complete merely
+indicates the API completion from HTTP, and not necessarily over the network.
+
+This prevents the need for data buffering at the Asp.Net Core Module level.

+        The <configSections> section controls the registration of sections.
+        Section is the basic unit of deployment, locking, searching and
+        containment for configuration settings.
+        
+        Every section belongs to one section group.
+        A section group is a container of logically-related sections.
+        
+        Sections cannot be nested.
+        Section groups may be nested.
+        
+        <section

+        The <configSections> section controls the registration of sections.
+        Section is the basic unit of deployment, locking, searching and
+        containment for configuration settings.
+        
+        Every section belongs to one section group.
+        A section group is a container of logically-related sections.
+        
+        Sections cannot be nested.
+        Section groups may be nested.
+        
+        <section
+            name=""  [Required, Collection Key] [XML name of the section]
+            allowDefinition="Everywhere" [MachineOnly|MachineToApplication|AppHostOnly|Everywhere] [Level where it can be set]
+            overrideModeDefault="Allow"  [Allow|Deny] [Default delegation mode]
+            allowLocation="true"  [true|false] [Allowed in location tags]
+        />
+        
+        The recommended way to unlock sections is by using a location tag:

+        The <configSections> section controls the registration of sections.
+        Section is the basic unit of deployment, locking, searching and
+        containment for configuration settings.
+        
+        Every section belongs to one section group.
+        A section group is a container of logically-related sections.
+        
+        Sections cannot be nested.
+        Section groups may be nested.
+        
+        <section
+            name=""  [Required, Collection Key] [XML name of the section]
+            allowDefinition="Everywhere" [MachineOnly|MachineToApplication|AppHostOnly|Everywhere] [Level where it can be set]

+        The <configSections> section controls the registration of sections.
+        Section is the basic unit of deployment, locking, searching and
+        containment for configuration settings.
+        
+        Every section belongs to one section group.
+        A section group is a container of logically-related sections.
+        
+        Sections cannot be nested.
+        Section groups may be nested.
+        
+        <section

+.PARAMETER Rollback
+    Default: $false
+    Rollback the updated files with the original files
+.PARAMETER ForceToBackup
+    Default: $false
+    Force to do the initial backup again (this parameter is meaningful only when you want to replace the existing backup file)
+.PARAMETER Extract
+    Default: $false
+    Search ANCM nugetfile and extract the file to the path of the ExtractFilesTo parameter value
+.PARAMETER PackagePath
+    Default: $PSScriptRoot\..\..\artifacts
+    Root path where ANCM nuget package is placed
+.PARAMETER ExtractFilesTo
+    Default: $PSScriptRoot\..\..\artifacts"
+    Output path where aspentcore.dll file is extracted
