  1. Auto-create Controller Actions from data entered into JavaScript/JQuery Ajax methods

    A great feature of many IDEs, including VS, is that you can define a function on the fly and automatically create a method stub for it.

    Wouldn't it be great if this could be done when you are making Ajax requests to the server?

    For example, say you wish to send data to an action using JQuery's $.post() method:

    You type $.post("MyController/MyAction", {data: "myData"}); into your front-end code, this new feature would then give you the option to auto-create an action "MyAction" in controller "MyController" with a string paramater "data" and a default return type of say, ActionResult.

    I'm still…

    • Covariant read-only collection interfaces

      I'm reopening my old request for "Typesafe immutable collections". We now have immutable collections but they are not covariant.

      Please add covariant read-only interfaces for lists, sets and dictionaries.

      Coming up with a good name might be an isssue since now both ReadOnly* and Immutable* prefixes are used by BCL while something like ListView sounds like a class from WPF. Maybe ReadableList ?

          • Add CanTellLength and CanSeekBackwards to System.IO.Stream

            • Add CanTellLength property to the System.IO.Stream:

            public virtual bool CanTellLength {
            get {
            try {
            var length = this.Length;
            return true;
            } catch {
            return false;
            }
            }
            }

            • Add CanSeekBackwards property to the System.IO.Stream:

            public virtual bool CanSeekBackwards => CanSeek;

            • Why
            Working with System.Net.Http.StreamContent I found that it caches the request in memory before sending the HTTP request if the length of the stream is unknown. And to perform the check if the length is known it uses CanSeek property - it mixes completely different concepts.
            I came up with conclusion:
            - The stream can tell…

            • Expose Collation Info of SQL Server Result Set via SqlDataReader

              The exact collation of each string field should be publicly available. The properties can be added to the DataTable returned by the GetSchemaTable() method, or they can be added as individual properties and/or methods of the SqlDataReader class, or a combination of both. The properties are:
              1) LCID
              2) SqlCompareOptions
              3) collation_name (e.g. Latin1_General_100_BIN2)

              The "LCID" and "SqlCompareOptions" values already exist in the "SqlDataReader" class, but are private or internal ( http://referencesource.microsoft.com/#System.Data/System/Data/SqlClient/SqlDataReader.cs,277 ). These would make sense to put into the GetSchemaTable output.

              The "collation_name" value is necessary due to the combination of "LCID" and "SqlCompareOptions" not being enough to…

              • XmlSerializer should recognize "True" as a valid boolean (Case insensitivity)

                Problem: "true" is recognized as valid by XmlSerializer, while "True" with a capital T is not.

                Expected behavior: Clearly, the value is unambiguous and valid and should be recognized as the boolean value "true".

                • make another foreach can be set and can use foeach similar to LINQ

                  now foreach is readonly,

                  I suggest ther can be a new foreach that can be set and have a different name like foreachset

                  and originally I have to write in an independent line as:

                  int[] iArray = new[] {1, 2, 3};
                  foreachset (int i in iArray)
                  {
                  i += 3;
                  }

                  .

                  and I hope it can be written like:

                  int[] iArray = new[] {1, 2, 3};
                  iArray.foreachset( i => i+=3);

                  its more Intuition.

                  or even just readonly foreach like LINQ is good,

                  I can do some readonly action such as

                  iArray.foreach( i => Console.Writeline(i));

                  -----------

                  Select in LINQ seems…

                  • Use namespace from another class in folder

                    If I create a new file in a folder, and the folder already has a file that has a portion that is within a particular namespace (i.e. a class, enumeration, etc. within that namespace), I want it to copy the topmost namespace of the topmost namespace-containing file in the folder.,

                    There is a related proposal here: https://visualstudio.uservoice.com/forums/121579-visual-studio-2015/suggestions/2162961-make-namespace-configurable-for-folder

                    With mine, no per-folder setting is required. It would simply look for "namespace foo {" and if it finds it, copy the namespace from the first occurrence of such.

                      • HttpClient get a connection timeout

                        I would like to have a timeout specifically for making the network connection to the server. When communicating between the client and server on the same network, normally if you don't connect in a few seconds, the connection will timeout. I would set the connection timeout pretty short. However, once the connection is made to the server, I would allow the request 30 or 60 seconds to be handled. If the network connection already exists, it would not apply.

                          • Upgrade Microsoft InteropForms Toolkit for Visual Studio 2015

                            I'm working with VB6 and Microsoft InteropForms Toolkit 2.1 ( https://www.microsoft.com/en-us/download/details.aspx?id=3264 ) , and that's really an amazing way for developing. It's allow me to develop in 3 languages - C#/VB.NET/VB6 interoperability and thus it make my developing progress run very fast without rewrite any old code of vb6. However, the latest version of InteropForms Toolkit- 2.1 is for Visual Studio 2010, please upgrade a new version for it. Thank you very very much!

                            • Dynamic class

                              Include support for dynamic class in .net.

                              This should allow the developer to take existing classes and either add more properties to the class in a new class, or remove properties.

                              This will allow the developer to create DTO classes from original classes, cutting away the properties he wants, but maintaining the ones he wants as well.

                                Microsoft often updates app for other system but windows. Why don't you make app on Windows better and support more more systems.

                                • Add .ToTitleCase() to String Class

                                  Add the method .ToTitleCase() to the String Class (or a similar one, such as .ToProperCase() or somesuch). Currently this requires pulling thread information to get the local user's culture information, and multiple extra lines of code. It would be much simpler to have an easily accessible method to capitalize the first letter of each word in a string.

                                  Current implementation:

                                  internal static string DisplayRandChar()
                                  {
                                  Character randomCharacter = new Character();

                                  CultureInfo cultureInfo = Thread.CurrentThread.CurrentCulture;

                                  TextInfo textConvert = cultureInfo.TextInfo;

                                  string displayText = ($"You are {textConvert.ToTitleCase(randomCharacter.name)} the " +
                                  $"{textConvert.ToTitleCase(randomCharacter.item)}-wielding {textConvert.ToTitleCase(randomCharacter.occupation)}!");

                                  return displayText;
                                  }

                                  Simplified implementation:

                                  internal static string DisplayRandChar()
                                  {
                                  Character…

                                    • Allow code within a compiled project to enumerate the conditional symbols used to build it

                                      While conditional symbols can alter the code generated there is no way for a compiled program to enumerate the symbols used to compile it.

                                      If this were possible then programs could log this information or notify administrators as to how the code was built, providing verification that the correct symbols were used for a given use case.

                                      Manual mechanisms could be build around the compilers, but those mechanisms might themselves become points of failure.
