I've got this working on my private (for the moment) branch. I could do
this merge by this weekend if folks will find it useful.

Hi Alla,
thanks for your prompt repsonse. In Python terms String('A') means
constructor with a string parameter AFAIK. When I use the python.exe
build against CLR 2.0 (from pythonnet-2.0-alpha2-clr2.0_115_py26.zip)
it works, but then it talks against .NET 2.0 while I want to talk to
the same 4.0 version as my .NET application.
With the example below using the .NET 2.0 version I get
>>> s = String.__overloads__[Char, Int32]('A', 10)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: type object 'String' has no attribute '__overloads__'
Basically it seems that the version of python for .net compiled
against .NET 4.0 runtime does not work out of box for me. I wonder if
somebody had more luck with this.

Hi Oleksii,
I have no experience with importing .net modules into Python.
I work on embedding Python into C#.
There is no such constructor String('A')for String class as you
use, which gets char.
You can see which constructors exists in:
http://msdn.microsoft.com/en-us/library/system.string.string.aspx
Example:
I read in http://pythonnet.sourceforge.net/readme.html
In most cases, Python for .NET can determine the correct
constructor to call automatically based on the arguments. In some
cases, it may be necessary to call a particular overloaded
constructor, which is supported by a special "__overloads__"
attribute on a class:
from System import String, Char, Int32
s = String.__overloads__[Char, Int32]('A', 10)
I hope you succeed,
Alla

*Subject:* [Python.NET] PythonNET 2.0 Alpha2 and .NET 4.0
Hi,
I am trying to use Python for .NET under VS2010 and .NET 4.0. I've
downloaded the pythonnet-2.0-alpha2.zip and changed the project
settings to use .NET 4.0 under VS2010 and recompiled everything.
The resulting python.exe can be run, and statements like "import
clr" and "from System import String" work (as the Python standard
library calls as well) until I try to instantiate a class as e.g.
s = String('A')
At this moment the Python for .NET seem to crash in nativecall.cs
at NativeCall.Call_3() at (the only) line
return Impl.Call_3(fp, a1, a2, a3);
with dreaded "Exception of type 'System.ExecutionEngineException'
was thrown.". Trying to instantiate Int32() object results in
"Attempted to read or write protected memory. This is often an
indication that other memory is corrupt."
Suggestions are more than welcome! Thanks in advance!
