What is the difference between IronPython and BOO ? Is there a need for 2 Python-like languages? IronPython is designed to be a faithful implementation of Python on the .NET platform. Version 1 targets Python 2.4 for compatibility, and version 2 targets version 2.5 (although most of the Python standard library modules implemented in C aren't supported). Boo 's stated aim is to be a "wrist-friendly [dynamic] language for the CLI." It takes a lot of inspiration from Python, but diverges on four main points: It's designed specifically to take good advantage of the .NET platform The designer

The issue: An unhandled exception in a thread entering the CLR from unmanaged code does not trigger the "normal" unhandled exception CLR processing. In the code below calling CSSimpleObject.GetstringLength() from C++ with "1" throws an exception in the calling thread (non-CLR-created thread), "2" throws an exception in a new Thread() (CLR-created thread). In case "1" CurrentDomain_UnhandledException() is never called. The Application Domain and the process will stay loaded and running, you will only get a FAILED. In case "2" (expected behavior) CurrentDomain_UnhandledException() is called. The

I passed .NET quiz, when I met a question like below one. Char ch = Convert.ToChar('a' | 'e' | 'c' | 'a'); In console we can see that output for ch variable is g . Can someone describe what is happening ? Thanks! This is not what it looks like at first spot. It is more of binary calculations on the int representation of these Char : Here is a full article explaining this with examples: Article So the binary result for the bitwise Or of these 'a' | 'e' | 'c' | 'a' is 103 . If you Convert that to Char, it is g Edit: I see this answer took more attention than I though it deserves more details.

To illustrate my question, consider these trivial examples (C#): object reference = new StringBuilder(); object box = 42; object unset = null; // CASE ONE: bad reference conversions (CIL instrcution 0x74 'castclass') try { string s = (string)reference; } catch (InvalidCastException ice) { Console.WriteLine(ice.Message); // Unable to cast object of type 'System.Text.StringBuilder' to type 'System.String'. } try { string s = (string)box; } catch (InvalidCastException ice) { Console.WriteLine(ice.Message); // Unable to cast object of type 'System.Int32' to type 'System.String'. } // CASE TWO: bad

Beyond the regular boring difference between Cast and As if i know that apple is a Fruit so I can use (Fruit)apple - and it throws an exception if it aint as value can be checked against null to see if succeeded [won't throw Exception...] However Ive been reading @EricLippert article about this and there was a nice sample about Nullable Value Types : short? s = (short?)123; int? i = s as int?; this won't compile... Cannot convert type 'short?' to 'int?' via a reference conversion, boxing conversion, unboxing conversion, wrapping conversion, or null type conversion Fine. so why this : short? s

Maybe I did not understand it right ... all the Parallel class issue :( But from what I am reading now, I understand that when I use the Parallel I actually mobilize all the threads that exists in the threadPool for some task/mission. For example : var arrayStrings = new string[1000]; Parallel.ForEach<string>(arrayStrings, someString => { DoSomething(someString); }); So the Parallel.ForEach in this case is mobilizing all the threads that exists in the threadPool for the 'DoSomething' task/mission. But does the call Parallel.ForEach will create any new thread at all? Its clear that there will

I've created system that uses CLR triggers to connect to WCF server and notify it about changes in DB. It runs ok on SQL server 2008 R2. Now im trying to migrate on SQL Server 2012. To use WCF i need to load SMDiagnostics.dll assembly along the others. Ive checked that clr is enabled in db , and set trustworthy to be "on", ive disabled WCF debuging, ive checked that SQL server runs under Local System account so there is no problems with permissions. Now my problem is that when i run following command IF NOT EXISTS (SELECT * FROM sys.assemblies asms WHERE asms.name = N'SMdiagnostics') create
