How can I use them in my .NET application to measure execution times of various parts of my application? I googled but surprisingly didn't find any great references....

Difference between Seq and Array for array value

I'm quite new in F#. I guess arrays are still collections, so I could use Seq for iterating the array like this: [|"a"; "b"|] |> Seq.map (fun f -> printfn "a") |> ignore;; But that doesn't work - it prints nothing. On the other hand if I use Array, it prints the strings: [|"a"; "b"|] |> Array.map (fun f -> printfn "a") |> ignore;; ...

Are there any C# documentation tools that use a markup other than XML?

I'd like a documentation tool that uses a less verbose markup. Filling my comments with XML just seems like an unnecessary eye sore, and a huge waste of key strokes should I have to edit something outside of VS. I spend a lot more time in the ruby world and would love to find something more like YARD. I have a feeling this is a pipe dr...

Protecting connection strings during dev

We need to protect connection strings during development. On servers we use DPAPI which works fine. DPAPI is not an option during dev since the connection strings will need to be decrypted on many machines. Some of the user names/password used for dev are rather sensitive and we don't want them floating around. It's fine for all the ...

Why has C# steered clear of this pattern? And how would you implement it instead?

SHORT FORM(!) In response the Jon Skeet's comment, what I want C# to be to do is to allow a generic, at compile time, to expand out and derive from one of it's generic parameters (as Kirk Woll demonstrates): public class Generic<TBase> : TBase { } This class, of course, would not be able to override any members of TBase (unless perh...

Windows Workflow 4, Persistance, and Data Services

Hi All, So I'm starting to work with the new workflow enginge (wf4) after previously working with 3.5. And I must say it is greatly improved!

Is there a straightforward way to copy a Type using reflection?

I realize this is a very strange question. Let me just say that I have my reasons. (I tend to write very long, wordy questions; I want to keep this one short.) If I have some type T, can I use reflection to define a new type, let's call it T2, that will basically be identical to T? What I'm looking for is essentially a dynamic way to do...

Add space between glyphs when drawing a FormattedText object

I am drawing a block of text using a FormattedText object and DrawingContext.DrawText(...) and I am wondering if there is any way to add more space between the glyphs. If not, I can always draw each glyph separately and manage the location so I can add the space manually, but I am hoping for an easier way. jorj ...

How should a WCF service implementation handle errors/faults without coupling to FaultContract

I understand the concept of Fault Contracts in WCF, but they seem to be tightly coupled to WCF and SOAP in particular. I've created a set of services that are separate from the contract definitions and the implementations could be used in many ways, not just WCF/SOAP. For instance, if I wanted to create a RESTful service, or just use t...
