Visual studio debugger: Break on entering an external function?
Hi, With "Just My Code" turned off and a source location/server, it's easy to step into functions that are not in your code. Is there a way to set a breakpoint on one of these, though?

So being able to access C#.NET assemblies from my Python code is necessary. I also wanted an IDE with auto-complete and smart indenting. PyScripter seemed like a good option, but can I ru...

Was is the performance of the Last() extension method for List<T>?
I really like Last() and would use it all the time for List<T>s. But since it seems to be defined for IEnumerable<T>, I guess it enumerates the enumeration first - this should be O(n) as opposed to O(1) for directly indexing the last element of a List<T>. Are the standard (Linq) extension methods aware of this? The STL in C++ is aware...
Getting XML serialization to automagically ignore non-serializable properties

To this end I need a means to XML serialize the property values of any classes that get passes, but ignoring any properties that cannot be XML serialized (e.g. any Image type properties). I could go t...

What does .NET give me, that Win32 does NOT?
What would the usage of .NET give me, that i don't have using Win32 - and sometimes maybe googling for some 50-100 Lines of code i can reuse? I am developing Win32 since it exists (> 15 years). Its straight forward and very robust, although sometimes it needs some more calls than you'd expect, and of course you need to keep track of han...
Disabling NICs or blocking all tcp connections
I was wondering if it's possible to use .NET to disable a certain network interface or, in alternative, to drop all the existing TCP connections (from the whole system) and then inhibit further creation. I'm asking this because I want to write a small C# utility that monitors the system and blocks networking (or at least TCP connections...
