thank you for your reply it's really appreciated :-) Agree totally with your considerations, there is lot to optimize in the code, but still that doesn't explain why the Java or the Dart version are much faster (and they don't even have structs). One could point out that it's like comparing apples vs oranges, but Java and C# are very close sharing common traits to the point that the two source codes can be compared line by line. So what's exactly the reason why .NET is so slow here? Do you have an idea?

Talking of C# and AngularJS, an alternative is to cross-compile C# to JavaScript (with compilers like Saltarelle). I have some projects written this way, but it's not an optimal solution because: you need a C# import library for Angular (that I've written myself but it's hard to cover all the package) Angular itself is very JavaScript oriented, with lot of hacks and tricks, doesn't fit well with C# At this point there is no Visual Studio integrated debugging for C#, you can only debug compiled JS code working with json and js in general, in C# you find yourself fighting with types, doing lot of conversions and things like that. The dynamic keyword helps but not much.

Ah - but I can delete this. You can then delete yours, me mine, you yours, and so on. Or now that your message text is gone, it doesn't matter anyway! :laugh: If you get an email telling you that you can catch Swine Flu from tinned pork then just delete it. It's Spam.

Thank you, it's more or less what I am trying to do, so it's going to be helpful. The only difference is that the result of my scripted "programs" would be web-like pages to be loaded in a navigational host application. Unfortunately it seems that the native WPF Navigation/Page model can't be used with uncompiled XAML.

Try to set AutoScaleMode of the form to NONE. Not sure if it helps, but there is a good article related to scaling http://en.csharp-online.net/Layout[^]
