NetExt is back. New commands added not yet included in this help. Use !whelp for all commands
Getting started
- Open WinDBG. Load netext
- Make sure you open the appropriate 32-bits or 64-bits extension (32-bits dumps require winbg 32-bits and netext 32-bits)
- For detailed help, run: ".browse !whelp"
- Run: "!windex -tree" and follow the instructions
- All the rest will be intuitive
- For scripts, see !wfrom and !wselect
- Download the training material here: [https://netext.codeplex.com/releases/view/611486] - Training material is NOW up-to-date.
COMPATIBLE WITH .NET 2.0 to 4.7.
Common Resources
This windbg debug extension works as data mining for .NET.
You can do select like queries to .NET objects including sublevel fields.
For example, to get the url of a HttpContext it is necessary to
- !do the httpcontext instance, get address of _request
- !do the HttpRequest instance, get the address of _url
- !do the URI instance, get the address of m_String
- !do the instance of the string object.
Using netext you only need to issue a command like:
!wselect _request._url.m_String, _response._statusCode from 0x242afe8
Or to list all requests that are "http:" and the status code is not 200 (OK) from ALL HttpRequests:
!wfrom -type *.HttpContext
where ( ($contains(_request._url.m_String, "http:")) && (_response._statuscode != 0n200) )
select $addr(), _request._url.m_String, _response._statusCode
calculated: 0n5731369072
_request._url.m_String: http://rviana-serv.contoso.com:80/TestClass/Service.svc/net
_response._statusCode: 0n401
calculated: 0n6802002784
_request._url.m_String: http://rviana-serv.contoso.com:80/TestClass/Service.svc/net
_response._statusCode: 0n401
It also works very well showing arrays (!wdo, !wselect and !wfrom) and providing link to the objects or showing the items value depending on the content of the array.
THE EXTENSION DOES NOT REQUIRE SOS OR PSSCORX TO WORK. It access .NET debugging API directly without intermediary.
Please use netext.dll for .NET 2.0-4.5.x. There are both 32 and 64-bits versions.

/short - Dump object addresses only (for .foreach processing)
/detailsonly - Show heap detail and areas (no object is shown)
/nothrottle - No limit for objects dumped per area. Otherwise will
show only first 500 per area if -type or -mt are not used
/start <expr> start address
/end <expr> - end address
/type <string> - List of types to dump with wildcards accepted
(eg. -type *HttRequest,system.servicemodel.*)
/mt <string> - List of Method Tables to include (eg. -mt 7012ab8,70ac080)
- If you just use !windex it will only show the first 500 objects of each heap area
- If you use -nothrottle, -type or -mt all results will be shown
- Don't use !wheap if you plan to search heap later or use !wfrom (use !windex instead)

If the current frame is managed, it will try to reflect to
source code in C# and create a symbol file to associate the
context address with the reflect source code line
Why it is useful:
================================
To understand why a component you do not have symbol (or source) files anymore is
not working anymore.
This command leverages ILSpy and PdbRestorer (special thanks to Marek Pokorny
for his blessing)
Syntax:
-------
!wmakesource
Example:
---------
Reflect and create symbol for a frame

Dump modules filtered by type or pattern.
The types are:
- Not from Microsoft
- Managed only
- Compiled in debug mode (managed code only)
Syntax:
-------
!wmodule [-debug] [-managed] [-noms] [-order] [-fullpath] [-name <partial-name>]
[-company <partial-name>] [-saveto <folder>]
Where:
-debug Lists only managed modules compiled in debug mode. Optional
-managed Lists only managed modules. Optional
-noms Lists modules which are not from Microsoft (it may contain false positives). Optional
-order The output will be sorted by name. Optional
-fullpath It includes the full path to the modules. Optional
-name <partial-name&> List only modules matching the pattern (e.g -name Contoso.MyLibrary*). Optional
-company <partial-name> List only modules from the company in the pattern (e.g -company TailsSpin*). Optional
-saveto <folder> When present it will save the selected module to an existing folder (e.g. -saveto "c:\mymods\"). Optional.

The ability to use functions is the most powerful feature of the extension.
All functions start with '$' sign.
Functions are what enable the data mining operations on the heap.
Below is the list by group.
Syntax:
------------

Where:
------------
<exprN> - it is an expression that can be:
- An integer, pointer or float number literal or expression
- A string literal or expression
- A boolean expression or literal (0=false, not 0=true)
- A field with or without inner fields separated by '.'
- A function or function expression
General Purpose:
----------------
$sqrt(<expr>) - Return the square root of the expression
$int(<expr>) - Return the integer part of a float number expression
$max(<expr1>, <expr2>) - Return the bigger value of two expressions
$if(<cond>, <expr1>, <expr2>) - If cond is true returns expr1 or expr2 if false
$poi(<expr>) - Read pointer from memory address <expr>
$isnull(<expr1>, <expr2>) - Return <expr2> if expr1 is null or <expr1> otherwise
$modulename(<expr>) - Return module path from module address
$typefrommt(<expr>) - Return type name from the method table in <expr>
$methodfrommd(<expr>) - Return method signature from method definition

NOTE: this extension is using C++ TR1 regex implementation and differences may occur
Current Object:
------------------
When using !wfrom with a filter every match will be send to the where and select list.
Sometimes you need to have control over the properties of the current object. Note that object functions
normally take no parameters
$addr() - Address of the current object
$typename() - Type name of the object
$mt() - Method table address of the object
$isobj() - if current object is not value type it returns 1
$isvalue() - if current object is value type it returns 1
$fieldat(<i>) - Return the current object's field with index <i>
$token() - Return metadata token of the current object
$module() - Return module address for the current object's type
$string() - Return first 1024 characters of the string if it is a string object
$chain() - Return the inheritance chain of the type of the current object
$containpointer(<address>) - Return 1 if any of the fields point to <address>
$containfieldoftype(<field-name>) - Return 1 if the object has at least a field with <field-name>
$implement(<type-name>) - Return 1 if the object inherits from <type-name>
$rawobj() - Return the string for Byte[] or Char[] array types
Examples:

Array Objects:
-------------------
$isarray() - Return 1 if current object is array or 0 otherwise
$arraysize() - Return the number of items of the current array
$arraystart() - Return the address of the first element of the array
$arrayitemsize() - Return the size of the array element
$items(i) - Return the i-th linear element of the array (range 0 - $arraysize()-1)
$rank() - Return the number of dimensions in the array
$arraydim(i) - Return the number of elements for the i-th dimension of the array

Field Functions:
----------------
$fieldoffset(<field>) - Return the offset of the field within the object (it does not add the method table
offset)
$fieldaddress(<field>) - Return the absolute address of the field
$isstaticfield(<field>) - Return 1 if field is static, 0 otherwise
$isvaluefield(<field>) - Return 1 if field is value type, 0 otherwise
$isobjfield(<field>) - Return 1 if field is object type, 0 otherwise
$fieldtypename(<field>) - Return type name of the field
$fieldmt(<field>) - Return method table of the field
$fieldtoken(<field>) - Return metadata token of the field
$fieldmodule(<field>) - Return module address for the field

$fieldfrommt(<address>, <mt-address>, <field-str>) - Return the field defined in the string at <address>
for a value type with Method Table <mt-address>
$rawfield(<field>) - Return the string for Byte[] or Char[] array fields
$toguid(<field>) - Return guid string for a guid field
$enumname(<field>) - Return the enumeration name for the field
*new* $isinstack(<field>) - Return true if field is rooted in stack (you can use $addr() to check current object)
*new* $stackroot(<field>) - Return the list of threads where the field is rooted in stack (you can use $addr() to check current object)
*new* $a(<field>) - Attribute a name to a field or expression (useful to avoid "calculated")
*new* $thread(<field>) - Return the thread id of a managed thread object
*new* $hexstr(<field>) - Return the hex string for Byte[], Char[] or Uint16 array fields (useful to print thumbprint)
*new* $ipaddress(<field>) - Return the ipv4 or ipv6 representation for System.Net.IPAddress fields
