Having recently updated an ASP.net MVC web app from MVC4 to MVC5 and from .NET 4.5 to .NET 4.7.2 I was expecting Razor views (.cshtml files) to use the latest C# compiler, especially since at Properties/Build/Advanced option for the web project one read “C# latest major version (default)”. However that was not the case and […]

Just came across the following case in C# that puzzled me momentarily, especially since the strings involved were long enough and the expression was broken on multiple lines: bool flag = true; string test1 = flag? "xa" : "xb"; string test2 = "x" + (flag? "a" : "b"); string test3 = "x" + flag? ...

At Trafilm project’s Metadata (http://github.com/zoomicon/Trafilm.Metadata) I have a linked data structure where a Film contains multiple Conversations which contain multiple L3SToccurrences, which in turn contain multiple L3TToccurrences. I had the need to calculate a list of all unique L2language values of L3TToccurrence grand-grand-children for ...

Wouldn’t it be nice if I could use in C# the following syntax? for (SomeType repeaterVariable       in SomeEnumerable       where someBooleanExpressionOfRepeaterVariable)   doSomethingUsingRepeaterVariable; e.g. use this one: instead of this one: BTW, if you wonder what FixTime does, it ...

I’d like to be able to do someFunctionReturningY(x){ somePropertyOfY=4; … }.DoSomething(); It should also support casting without needing parentheses in the following type of statement: Z zzz = (Z)functionReturningY{somePropertyOfZ=…; … };   The same pattern should work for enums too apart from object instances. It is ...

At TrackingCam app (http://TrackingCam.codeplex.com) I have the following WPF code, where cbTrackingPresenter is a CheckBox control defined in my MainWindow’s XAML: private void cbTrackingPresenter_Checked(object sender, RoutedEventArgs e) {       if (cbTrackingPresenter.IsChecked == true) ...

Sometimes when you catch an exception in .NET, the message it prints out isn’t very informative, since it is wrapping another exception that had been thrown a bit inner in the code. That exception is in that case accessible via InnerException of the Exception instance. That inner exception is also an Exception, so one would […]

it would be nice if C# supported syntax like: public static DependencyProperty Register(static DependencyProperty x, string name, Type propertyType, Type ownerType, FrameworkPropertyMetadata typeMetadata) that is static extension methods for classes, that can be invoked without a class instance (just with the class type), apart from normal ...

When using http://github.com/zoomicon/ZUI I would like to write: FloatingWindow window = new FloatingWindow() {   Content = display,   Title = IconText = title }; but I have to write: FloatingWindow window = new FloatingWindow() {   Content = display,   Title = title,   IconText = title }; instead. For consistency, ...

My comment at: http://visualstudio.uservoice.com/forums/121579-visual-studio-2015/suggestions/4272089-support-implicit-interfaces-for-code-reuse It would be nice indeed if one could define at the client object’s side a static interface that is a subset of the methods of a server (or serving if you prefer) object (it is only the view of the ...

It is rather unfortunate that C# doesn’t support constants in interfaces, whereas Java does. If IL (intermediate language) that C# usually compiles to (when not using AOT that is like in .NET Native or Xamarin iOS) doesn’t support this, then the compiler could create a special sealed class to carry the constants. Then, wherever ...

It would be nice if one could write in C# (and maybe in other .NET languages too): s = s.SomeMethodOfS(…)… as s .= SomeMethodOfS(…)… that is to have a .= operator, similar to += and other shorthand experession operators see screenshot for an example usecase from the opensource project FoscamController     Ideally, ...

It would be nice if one could rewrite this C# snippet: public SortedDictionary<string, UObject> GetObjects() {   SortedDictionary<string, UObject> result = new SortedDictionary<string, UObject>();   using (ReadTransaction xact = namingSchema.ReadTransaction())     foreach (ObjectName.RowType row in ...

It would be nice if one could define methods inside other methods so that they are only accessible in the context of the parent method. In Pascal one could define them at the start of the parent method, before any other commands, but after local variables block, so they could also access the variables of […]

Trying to reuse the conditional value of a switch statment in C# at the fallback “default” code block of it, and looking up if that was supported in C#, I found the a related discussion at: http://stackoverflow.com/questions/29628507/c-sharp-get-switch-value-if-in-default-case I added a comment there and also elaborated it a bit more at a ...

Instead of having to write in C#       speechRecognizer = CreateSpeechRecognizer();       if (speechRecognizer != null)       {         speechRecognizer.SomeProperty = someValue;         ...

This is a suggestion I’ve just sent in via Visual Studio’s “Send a frown” feature (rewritten here a bit differently from memory, since that feedback channel doesn’t allow you to access your previous feedback as the Microsoft Connect or the Uservoice site does) : Instead of having to write try {   … } catch […]

This is a suggestion I’ve just sent in via Visual Studio’s “Send a frown” feature: Instead of writing statements like:   List<CultureInfo> result = new List<CultureInfo>(); in C# I’d prefer to be able to write   List<CultureInfo> result = new (); inside the () one would be able to pass contructor parameters ...

In C/C++ and C# one has useful prefix (++index) and postfix (index++) increment operators and corresponding decrement ones. Although they have a single operant, they’re not working like functions as single + or – prefix would do, but instead they cause side-effects – they edit the variable passed to them. The prefix increment operator first ...

Following up on my last post: http://zoomicon.wordpress.com/2012/07/04/how-to-compile-code-that-uses-wpf-decorator-type-in-silverlight/ I’m copying from a mental note I added to: http://stackoverflow.com/questions/4936941/using-a-using-alias-class-with-generic-types/11334359: As shown at: http://msdn.microsoft.com/en-us/library/sf0df423.aspx and ...

I was hoping C# would someday add static extension support for constructors too (apart from classic methods), that would help a lot in source-level compatibility layers (for example at my WPF_Compatibility project for WPF syntax in Silverlight, which one can find under the ClipFlair source base). However, according to : ...
