  1. 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.

          • 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.

              • Visual studio 2012 Update 4 is not genrating a .mdf file nor .trx file for codedui test executions, it is difficult to track executions.

                After execution ( Like in VS2010) it should genertae a .trx or .mdf file in the TestResults folder whihc will be easier to track TestExecution Results.

                • Add tail call elimination to the C# compiler

                  Sometimes algorithms can be expressed far more elegantly in a tail-recursive form. The problem with that is the memory footprint, and possibly overflowing the stack. Though the 64bit JIT'er may sometimes decide to optimise the tail call, there are no guarantees, leaving you with no choice than to re-write the algorithm, avoiding tail calls. Having the compiler eliminate tail calls would let developers express algorithms in different ways, which may be more suited for the problem, while also helping developers who are not aware that their tail recursive algorithms may be problematic.

                  • In ModelMetada class in mvc2, if property is returning IEnumerable then there is no need to check for null.

                    if (_properties == null) {

                    • Integrate PHP language with PDO extension for MySQL.

                      There should be ability to use the online powerful PHP functions inside any C# application, as PHP is nowadays is very advanced and reliable language for online processes (server side)... and let other functions (C# functions) to care about the offline properties (local side)...
                      PHP Check for files online, get values, also in logging in/out for online applications, and sure the most important point in integrating PHP language inside C# applications is to have PDO extension to connect to the online MySQL databases and function with them.

                      • Enum Type Inference

                        Allow skipping the enum type qualifier when it can be inferred.

                        Example:

                        enum SelectKind
                        {
                        All,
                        Single
                        None,
                        }

                        public void Select(SelectKind kind)
                        {
                        switch(kind) {
                        All: ....
                        Single: ....
                        }
                        }

                        Select(All);

                        And privide an 'SelectKind.All and All is ambiguous' if there's some other symbol called All.

                        • Allow to use an inherited constructor

                          If you inherit from a class you often have to write code where you just create a constructor and call the base class with the same parameters. It would be great, if I could use the constructors of the base class instead.

                          • Add Mixin support

                            Composition is always a pain when we have to bind all method from interface to object that really implement it

                            The code often looks like messy and complex for nothing.

                              • Add c++ const/mutable equivalent like in C++ into .NET

                                1)
                                When develop common libraries it is hard to protect data from 3rd side modifications.
                                It is require deep copy what sometimes not acceptable (due to performance or memory issues),
                                In native C++ was really cool thing: const/mutable modifiers for classes, functions and function parameters.
                                It should be really nice if it will be added into one of next version of C#.

                                2)
                                Sometimes it is cool to mark some variable as final (to notice that it shall not be modified in rest of a function.
                                In C++ was great thing const for variables in methods.
                                It is also highly…

                                • Add a new "View" option to ListView.

                                  VerticalList

                                  ListBox lacks functionality and ListView is the next best thing. The only problem is the fact that if I want a vertical list, I have to put it in details mode, add a column and then set HeaderStyle to none.

                                  Wouldn't it be better to just have a vertical list option?

                                  • Value arrays with constant length

                                    Now you only can create an array with an extra indirection, because arrays are objects, and you access it through that reference. An array that is **** out in memory like in C++ would be pleased, it would mean much in performance in some cases. (Not just because of the lack of the extra indirection but it could be **** in memory right next to its related datas.)

                                    now: int[] playerPoints=new int[4];
                                    desired sg. like: int[4] playerPoints; // where "playerPoints" is not of a reference type, but a value type

                                    • Add const keyword to method/parameter signatures in C# (Similar to C++?)

                                      Add support for a const keyword that can be applied to method parameters,

                                      e.g. public void MyMethod(const MyClassA myInstance);

                                      It would prevent any state changes to MyClassA and any instances referenced by MyClassA for the life time of the method invocation.

                                      This would inform clients at compile time whether a method is likely to be corrupted or changed.

                                      I believe this is similar to how the const keyword behaves in C++?

                                      • Add a programming model for Regions

                                        Regionizer is an open source Visual Studio 2010 package (will be converted soon to 2012) that formats code into regions;

                                        I have been told that Regions do not have direct object model in the DTE, that the values are stored in the .suo file for each user.

                                        Please allow a programmable way to collapse all regions.

                                        • Allow exclusion of some namespaces from remove and sort unused usings

                                          Allow exclusion of some namespaces from remove and sort unused usings. I like to keep my usings / imports minimal but would prefer to always have System and System.Linq for example. Giving me an exclusion list would give me this functionality. Also the ability to set remove and sort unused using to happen on file save would be useful.
