How to use XAML outside of presentation layer (WPF/Silverlight) ?
XAML is supposed to be "Extensible Application Markup Language" - i.e. a generic, flexible framework for creating application markups. However, most searches for XAML yield either WPF or Silverlight-specific materials. The only exception at this time (that I am aware of) is Oslo framework (M-language & co.) - proving that XAML can be us...

How do I implement a System.Type property in markup for a User Control?
This is a follow up to another question of mine where I first found this problem. If I create a public property on my User Control, with a type of System.Type, I cannot use a normal string representation of the type, e.g. System.Int32, as a declarative markup attribute value for the property. It seems I need to uncover whatever it is t...

Hi there. I am currently researching how to write .NET code that can be injected into another .NET process and override function return values.

Multiple assertions when unit testing constructor?
I'm trying to unit test a class with 2 constructors. Each constructor has multiple parameters that set public properties. My question is, should I have only 2 unit tests with multiple asserts to check that each property was set OR a test for each parameter for each constructor? Public Person(string name, string phone, string birthday)...
Seeking One-Size-Fits-All Context Based Storage
First off, I wish context based storage was consistent across the framework! With that said, I'm looking for an elegant solution to make these properties safe across ASP.NET, WCF and any other multithreaded .NET code. The properties are located in some low-level tracing helpers (these are exposed via methods if you're wondering why they...

I have a stand-alone WinForms application, let's call it "Program A." Program A let's a user create a file and save some information to it. Program A also exposes some public classes. Another stand-alone WinForms application ("Program B") references Program A, and uses some of its public classes. However, some of Program A's classes n...
.net - unable to convert code from c# to vb.net due to incremental operator or automatic string conversion (I think)
I am writing a library in VB.NET in which I have added, among others, a class originally written in C# but converted into VB.NET. I don't know much about C# so therefore I have used online C# to VB.NET-converters. Now I am stuck with some code which I believe the online-converter was not able to "translate" properly. When running the co...
