Often I explain to people that there are a lot of .NET languages, because the .NET IL is rich, so the individual languages can focus on the IL pieces they do best.
This also means, that most languages have some support for specific pieces of IL that other languages do not have support for.
The IL Exception Filter feature is one such thing. It is supported by for instance VB.NET but not by C# as Junfeng Zhang explains:
C# does not support exception filter. However, VB and IL support it. To add exception filter to C#, we can build a function in VB or IL, then call it in C#.
Read his full article for the complete code.

For a project, I got a preconfigured VM for a client.
Certain projects they used gave this message:
—————————
Microsoft Visual Studio
—————————
The selected file cannot be opened as a solution or project. Please select a solution file or a project file.
—————————
OK
—————————
It appeared the didn’t do a full Visual Studio installation, so certain project types didn’t load.
This case it was Visual Studio 2008 and VBPROJ types, as Visual Basic .NET is way easier to do Office automation than C#.
In C#, you need truckloads of Type.Missing, which you do not need in VB.NET; Visual Studio 2010 made this easier, but you still often need them.
Lesson learned: always build all projects when you get a development VM, and prefer to install the VM yourself.

Often you work with projects not having the latest stuff.
Sometimes that is a good thing: latest stuff is not always best :-)
In this case, the client had Office 2003, and needed to do some Excel automation from .NET.
The development systems however had Office 2007 on it, so importing Excel defaults to the Office 2007 Primary Interop Assembly: Office version 12 in stead of 11. Read the rest of this entry »

While it is still free…
The current version: http://reflector.red-gate.com/Reflector.zip
The “Check for Updates” entry in the “Help” menu checks this URL: http://reflector.red-gate.com/Reflector.version
Which currently returns:
6.6.0.30
6.1.0.0
http://reflector.red-gate.com/Download.aspx?File=Reflector&Client={Client}&Version={Version}
When Reflector detects there is a new version, you get a dialog like this:
—————————
.NET Reflector
—————————
A new version of .NET Reflector is available. Do you want to install automatically?
—————————
Yes No
—————————
When you press [Yes], it starts downloading from a URL that depends on the current version: http://reflector.red-gate.com/Download.aspx?File=Reflector&Client=Reflector&Version=6.5.0.135
{Client} was replaced by Reflector, and {Version} was replaced by 6.5.0.135 (the version of the currently running Reflector).

Recently, I wrote a bunch of code both in C# and Delphi to verify if two hosts are on the same IPv4 network.
Even though the public IPv4 address space is exhausted (IANA recently allocated the final two IPv4 blocks of their primary pool to APNIC, then allocated the five remaning /8 IPv4 blocks to the RIRs, thereby depleting the IPv4 pool), they are still used a lot, especially in private networks.
Over the next couple of weeks, you will see a couple of blog posts explaining:
- how to get the IPv4 addresses and network masks of network interfaces in your computer
- how to convert those to and from strings
- how to convert a host-name to a list of IP addresses
- how to lookup the current host-name
- how network masks are related to counting leading/trailing ones and zeros
- how to compare two IPv4 addresses given they have the same network masks
Those blog posts will have sample code in both Delphi and C#. And there will be unit tests to verify the underlying code.

Each time I need to do Office COM interop, I wish they had overloaded methods: all those Type.Missing entries, and speed issues.
I know C# 4.0 makes missing parameters easier, but a lot of projects are not yet in Visual Studio 2010.
So this C# Excel Interop Use page by Sam Allen comes in handy.

On the one hand it is good to be able to do things as early in the application startup phase as possible.
On the other hand: What’s next? A PrePreApplicationStartMethod that allows you to fiddle with the PreApplicationStartMethod behaviour?

If you use Visual Studio 2005 for some old projects that have not yet been converted, and they open very slowly: read this post on If Your Visual Studio Solutions Open Slowly Check WebsiteCache by Thomas F. Abraham.
Emptying your WebsiteCache directory solves the issue: it had about 30-thousand empty directories in it.
The location depends on your Windows version:
- Windows XP, Windows Server 2003 and below:
“%USERPROFILE%\Local Settings\Application Data\Microsoft\WebsiteCache”
- Windows Vista, Windows Server 2008 and up:
“%USERPROFILE%\AppData\Local\Microsoft\WebsiteCache”
This bug has been fixed in Visual Studio 2008 and up.
