    • using keyword over methods

      Today the "using" keyword can be used to create try/finally blocks in a easy and safe manner. The problem is that using keyword requires an IDisposable instance.
      But in many situations we have a start/end approach, lock/unlock or similar that do not return any value and, surely have a better performance if no helper object is created.
      So, I think that it will be great if void methods can be marked with "finalizer" methods, so when used in a using clause, the compiler can create the right begin/end block.

      I have a sample at: http://www.paulozemek.com/Polarlight.TestPage.aspx

      There, the Initialize method is…

      • Implement WPF/Silverlight Control Template extraction

        Expression Blend has a great feature that allows users to extract the template of a control (Edit Template -> Edit Copy) and conveniently stores it into a Resource Dictionary. Having this feature in VS would be great, because blend maybe nice, but isn't as responsive as VS.

        • Property Initializer

          In addition to get{} / set {} it would be handy to have an init {} block on Properties

          e.g. The new [CallerMemberName] allows us to call the following without hard coding the proprety names:

          protected bool SetProperty<T>(ref T storage, T value, [CallerMemberName] String propertyName = null)
          protected bool ValidateField([CallerMemberName]string propertyName = null) ....
          etc.

          where ValidateField runs any validations that have been defined for a given field:
          eg. protected Dictionary<string, Action<string>> Validations = new Dictionary<string, Action<string>>();

          The only hassle is that the Validations need to be defined seperate to the Property and so require the property name to be…

          • Operator Try get Index Otherwise.

            I would like to Handle Indexing Exceptions by adding Default value after index.

            I will Show the operator as @.(just an example sign to clarify)

            Example 1:

            string[] args = new string[3];

            string str = args[4] @ "default" ; // Try get args[4]. otherwise "default"

            Example 2:

            List<int> RGBA_Color = new List<int> {55, 55, 55};

            int alpha = RGBA_Color[3] @ 0 ; // Try get value otherwise 0

            Example 3:

            Dictionary<string , Action> _dic;

            _dic["Key"] @ (() => { }) (); // Try get value otherwise

            This can really help Improve code readabilty. Specially in cases that we have unknown…

            • Add a "fluent" keyword to c#

              I write a lot of code like this:

              public MyClass DoSomthing()
              {
              // snip //
              return this;
              }

              For fluent style code (useful for Razor html helpers):

              @html.MyClass.Dosomthing().SomthingElse().etc();

              What I propose is a fluent keyword that can be used when defining the method, so the above method would become:

              public fluent DoSomthing()
              {
              // snip //
              }

              I believe this would be useful as a lot of the time our class definitions can be quite complex, imagine making an editor control, the class definition would be something like ‘MyEditor<TModel, TValue>’

              Replacing this sort of definition and removing the need for…

              • Generic pointers

                It would be great to have generic pointers within C#.

                It is quite painful to have the function written for double, byte...

                e.g.

                private Matrix<float> Cast( Matrix<byte> m) {//do the job}
                private Matrix<float> Cast( Matrix<int> m) {//do the job}
                ...

                instead of
                private unsafe Matrix<float> Cast<T>( Matrix<T> m)
                {
                T* mPtr = m.Ptr;

                //do the job
                }

                The CIL and thus CLR itself supports generic pointers. Why would not C# also ?

                • C#: Implement "Outline Statement Blocks" just like the one you have for C++

                  Today in C# you have outlining for methods, properties, classes, namespaces and regions, this is great but not enough.

                  1. First of all we want this for all statement blocks like if, while, foreach, for, using and so on.

                  2. It would also be great if any selection in the editor could be collapsed.

                  3. In addition to showing the content of a collapsed section when hovering over the boxed "..." at the end of the collapsed section "HeadLine", the same should content should be shown when hovering over a plus(+) sign in the "Outline column" to the left of…

                  • Allow fixed size arrays in safe context

                    unsafe struct X
                    {
                    public int i1;
                    fixed int a[4];
                    public int i2;
                    }
                    The struct needs not to be marked unsafe since int[4] is nothing but a four anonymous ints **** out sequentially. They should be treated not as array, but like any ordinary ints with a non-standard names (a[1], a[3], a[a[a[3]]]).

                    • Make BulkObservableCollection<T> public to the core .NET Framework

                      Using WPF and ObservableCollection<T> has serious performance issues if you need to add large sets of collection items at once, which is well known today. Each updated item fires multiple events that have significants performance costs.

                      There are hundreds, if not thousands, of custom implementations on the net to overcome this problem and that have their own, more or less adventurous, way of adding a new "AddRange()" method that does not fire all those events for each element but only once once at the end up the collection update.

                      There is already an existing implementation written by Microsoft, the BulkObservableCollection<T>…

                            • C# Regex Literals - Seamless Regular Expression integration with .NET Framework and C# Language Grammar

                              Create a seamless integration of the .NET library code base and language grammar with regular expressions, through new methods signatures and the lexical definition of regex literals.

                              I want to able to write regex literals like:

                              /[a-z]/cim // standing for new Regex("a-z", RegexOptions.Compiled | RegexOptions.IgnoreCase | RegexOptions.Multiline)

                              I want to be able to write the following code:

                              Instead of: "some string".Split(new char[] { ' ', '*' })

                              It could be: "some string".Split(/[\s\*]/)

                              And the same could work for Replace(), IndexOf(), Substring() and so on.

                              Especially for replacing scenarios, a especial 'g' flag (or 'a') would mean global/all matches, for replacing…

                              • Provide non-default value initializatoin for arrays in C#

                                Can we please have the ability to assign a non-default(0) value to array elements in C#. When I look at the cost of array construction, I see varied results, sometimes it is comparable to the cost of a loop, 400,000 - 1,200,000 ticks for a 1024x1024 float array[,]. Other-times it seems to drop right down to about 2000 ticks. I can only explain this by the runtime either having knowledge about whether chunks of memory have already been set to zero, or else initialization is using memcpy or some such mechanism under the hood to set zero. I would guess…

                                • Add Visualizers which allow us to visualize list & dictionary data while debugging

                                  Like Datatable in .Net Framework allows us to view data in the datatable, it should allow to view list data like datatable.

                                  • Support for variadic generic arguments in C#

                                    I think it would be nice to have variadic generic arguments on c#

                                    something like this:

                                    class Entity
                                    {
                                    void Add<T, in TArgs ...>(TArgs args)
                                    where T : Item
                                    where T : new(Entity parent, TArgs args)
                                    {
                                    items.Add(new T(this, args));
                                    }
                                    }

                                    This is a lot safer than getting T constructors via reflection and receiving params object[] as arguments.

                                    Maybe this could also be used to declare interfaces

                                    interface ITest<in TArgs ...>
                                    {
                                    void DoSomething(TArgs args);
                                    }

                                    delegate TResult Func<in TArgs ..., out TResult>(TArgs);

                                    public static void SafeTest<T, in TArgs ...>(this T t, TArgs args)
                                    where T : ISample<in TArgs> …

                                      Add a WITH Statement to C# like the one in Visual Basic. For example:

                                      with (object) {
                                      .property1 = value1;
                                      .property2 = value2;
                                      }

                                      • Debug Watches work for variables across closures and auto-enumerators

                                        C# yield return and await keywords cause a lot of magic in the compiler, that defeats most useful debugging in that variables that appear in source code to be local variables in the method are not available (no doubt because they're not actually in the current stack frame due to all the compiler-generated types. Nevertheless, it makes debugging difficult.

                                        • Add index to foreach statements

                                          Add index to foreach statements so developers don't have to declare their own indexes to track counts.
