I’ve seen this question coming up a few times, and bumped into this at a client recently: the UAC dialog coming up when debugging a 32-bit executable.
This is caused (more details below) by Installer Detection Technology introduced in Windows Vista (with UAC) and tightened in more modern Windows versions.
The solution is to either:
For software you don’t have source code for, you can alter the manifest with a requestedExecutionLevel element: Fixing the way Vista Auto-detects Installers – Ben’s Writing.

It is almost 3 years that Ostemar wrote an interesting answer on Stack Overflow to the question
Why does .NET use banker’s rounding as default? – Stack Overflow.
Few people (even many programmers don’t!) know about rounding and how it can influence software, let alone what bankers rounding does so lets set a few things straight first.
Rounding matters. Depending on the kinds of software you write, it matters a little, or a lot.
For instance, in these categories, it can matter an awful lot:
Bankers rounding means rounding half even. Which means that #.5 will round to the even number closest to #.
In bankers rounding, 1.5 rounds to 2, 3.5 to 4 as does 4.5, -1.5 rounds to -2, -3.5 to -4 as does -4.5.
This is called “unbiased” because for reasonable distributions of y values, the expected (average) value of the rounded numbers is the same as that of the original numbers.
This is contrary to what the majority of people are accustomed to: Round half away from zero is taught in most countries (even for the Dutch, despite the alias “Dutch Rounding” for round half to even).
Round half away from zero rounds 1.5 rounds to 2, 3.5 to 4 and 4.5 to 5. Negative numbers round like this: -1.5 rounds to -2, -3.5 to -4 as does -4.5 to -5.
This is only free of overall bias if the original numbers are positive or negative with equal probability.
In short, .NET uses bankers rounding because it follows the IEEE 754 rounding rules.

Reading c# – Type.IsSubclassOf does not behave as expected – Stack Overflow, I found this very interesting link via Assembly Load Contexts Subtleties at Sasha Goldshtein’s blog (I love the name of the blog: All Your Base Are Belong To Us).
He explains the reasons for the error message
System.InvalidCastException: Unable to cast object of type ‘Plugin.MyPlugin’ to type ‘Plugin.MyPlugin’.
Actually his blog entry is an abstract of a 200+ page thesis on that is also recommended reading: Flexible Dynamic Linkin for .NET (by Anders Aaltonen, Alex Buckley and Susan Eisenbach).

Igor Ostrovsky wrote a few very nice MSDN magazine articles. Not all of them have ended up in the list at MSDN magazine, so here is a more complete list:
Though the articles show the majority of sample code in C#, the actual topics are of great interest to any developer writing .NET code or interfacing to it.

Ever since I started .NET programming after .NET Beta 1 Arrived in 2001, I found that many people struggle with the relation between assemblies and namespaces.
So I was glad that I posted this answer about 2.5 years ago on StackOverflow. Below is the slightly edited form:
People are easily confused by the namespace/assembly thing, as it decouples the concept of where your code is physically located (the assembly) and how you reference it:
- logically reference is by using the namespace
- physical reference is by referencing the assembly
I usually explain the relation using the word contribute:
- An assembly can contribute to multiple namespaces.
For instance, theSystem.Data.dllassembly contributes to namespaces likeSystem.Data(e.g. the classSystem.Data.DataTable) andMicrosoft.SqlServer.Server(e.g. the classMicrosoft.SqlServer.Server.SqlContext).- Multiple assemblies can contribute to a single namespace.
For instance both theSystem.Data.dllassembly and theSystem.Xml.dllassembly contribute to theSystem.Xmlnamespace.
Which means that if you use theSystem.Xml.XmlDataDocumentclass from your project, you need to reference theSystem.Data.dllassembly.
And if you use theSystem.Xml.XmlDocumentclass, you need to reference theSystem.Xml.dllfrom your project.(the above examples are .NET 4.0, but likely hold for previous .NET versions as well).
Danny Thorpe explained the concept of namespace and internal really well, so I won’t go into detail about those.
Ever since I started .NET courses 10 years ago, I draw a table explaining assemblies and namespaces like this:
| Assembly | Namespaces it contributes to | ||
|---|---|---|---|
| ↓ | System.Data | Microsoft.SQLServer.Server | System.Xml |
| ↑ Example classes | |||
| System.Data.dll | DataTable | SqlContext | XmlDataDocument |
| System.Xml.dll | — | — | XmlDocument |

The continuation of the trip down memory lane…
Few people know the name Peter Sollich, as he always chose not to be a public figure (for instance, he is absent on the Outstanding Technical Achievement video).
Peter has been very important for both the Delphi and the .NET worlds: he was the original author of the 32-bit product that became the Delphi x86 compiler.
A few interesting links came up when using his name in some Google searches.

Having done quite a bit of Windows CE development work in .NET, I totally support the below UserVoice request: re-add support for Windows CE in Visual Studio 2010.
Please vote both the underlying Microsoft connect request, and the uservoice entryif you support it too!
Bring back support for Smart Device Extensions
Microsoft caused outrage when without warning or explanation they dropped support for the Smart Device Extensions. Meaning that there is no support for both managed (Compact Framework) and unmanaged (C++) development for the Windows CE platform.
Microsoft promised support would be added by the time VS2010 was released but then back tracked, to date the official line is use VS2008. This product is nearly 4 years old, it is becoming increasingly more impractical to use VS2008 solely for the purpose of developing for the Windows CE platform. Many development teams invested heavily in the benefit of having a single UI for both embedded and desktop development, with the advent of the Compact Framework skill sets and more importantly the code base could easily be shared across platforms. This is now no longer true, as the desktop development/source control/build/test environments have moved on the embedded development environment is stuck in the past. This means duplication of code, duplication of effort and increased cost.
Anyone wanting to start developing for Windows CE has to first buy an MSDN subscription because you can no longer buy VS2008 retail.
As support for Smart Devices has been inherent in VS since VS2003 many people have been caught out when upgrading to VS2010, in many cases those who make their living in the embedded world are now stuck with no upgrade path. Microsoft has refused to comment or discuss the future of embedded development, this silence has forced many to look at alternative platforms.
One of the top voted suggestions on the Connect site was to restore Smart Device Extension support in VS2010, Microsoft has ignored this in typical fashion.
See the Connect Item.

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).

At the EKON13 conference, I will be presenting a talk about record and class helpers.
This morning, my laptop did “beeeeeeep beep beep” followed by a deadly silence.
It will take a while before my spare laptop arrives at the hotel and my Vista and VM’s are working again.
So I needed to redo some of my preparations to make sure that I can do a ‘plan B’ if restoring on the spare laptop fails.
Hence below a list of useful links, not yet in a particular order, but it saves you browsing through search engine results sifting the good from the not so good info.
