- Catches exceptions thrown in C# iterators (yield returns) and rethrows them in python ([#475][i475])([#693][p693])

- Implemented GetDynamicMemberNames() for PyObject to allow dynamic object members to be visible in the debugger ([#443][i443])([#690][p690])

- PythonException included C# call stack
2931
- Reattach python exception traceback information (#545)
3032
- PythonEngine.Intialize will now call `Py_InitializeEx` with a default value of 0, so signals will not be configured by default on embedding. This is different from the previous behaviour, where `Py_Initialize` was called instead, which sets initSigs to 1. ([#449][i449])
3133
- Refactored MethodBinder.Bind in preparation to make it extensible (#829)
34+
- Look for installed Windows 10 sdk's during installation instead of relying on specific versions.

Python for .NET is a package that gives Python programmers nearly
12+
seamless integration with the .NET Common Language Runtime (CLR) and
13+
provides a powerful application scripting tool for .NET developers. It
14+
allows Python code to interact with the CLR, and may also be used to
15+
embed Python into a .NET application.
16+
17+
Calling .NET code from Python
18+
-----------------------------
19+
20+
Python for .NET allows CLR namespaces to be treated essentially as
21+
Python packages.
22+
23+
.. code-block::
24+
25+
import clr
26+
from System import String
27+
from System.Collections import *
28+
29+
To load an assembly, use the ``AddReference`` function in the ``clr``
30+
module:
31+
32+
.. code-block::
33+
34+
import clr
35+
clr.AddReference("System.Windows.Forms")
36+
from System.Windows.Forms import Form
37+
38+
Embedding Python in .NET
39+
------------------------
40+
41+
- All calls to python should be inside a
42+
``using (Py.GIL()) {/* Your code here */}`` block.
43+
- Import python modules using ``dynamic mod = Py.Import("mod")``, then
44+
you can call functions as normal, eg ``mod.func(args)``.
45+
- Use ``mod.func(args, Py.kw("keywordargname", keywordargvalue))`` or
46+
``mod.func(args, keywordargname: keywordargvalue)`` to apply keyword
47+
arguments.
48+
- All python objects should be declared as ``dynamic`` type.
49+
- Mathematical operations involving python and literal/managed types
50+
must have the python object first, eg. ``np.pi * 2`` works,
51+
``2 * np.pi`` doesn’t.
52+
53+
Example
54+
~~~~~~~
55+
56+
.. code-block:: csharp
57+
58+
static void Main(string[] args)
59+
{
60+
using (Py.GIL())
61+
{
62+
dynamic np = Py.Import("numpy");
63+
Console.WriteLine(np.cos(np.pi * 2));
64+
65+
dynamic sin = np.sin;
66+
Console.WriteLine(sin(5));
67+
68+
double c = np.cos(5) + sin(5);
69+
Console.WriteLine(c);
70+
71+
dynamic a = np.array(new List<float> { 1, 2, 3 });
72+
Console.WriteLine(a.dtype);
73+
74+
dynamic b = np.array(new List<float> { 6, 5, 4 }, dtype: np.int32);
75+
Console.WriteLine(b.dtype);
76+
77+
Console.WriteLine(a * b);
78+
Console.ReadKey();
79+
}
80+
}
81+
82+
