  1. Allow Unsafe Code and Pointers in VB.

    Make it so pointers can be cast in unsafe contexts for complex interop coding ...

    Public Unsafe Function x(y as SomeStruct) As ResultStruct
    Dim p As Object? ' use Object? as an alternative to (void *)
    p = InteropCall(y?) ' use ? to get the address of something.
    Return CType(@p, ResultStruct) ' use @ to dereference.
    End Function

    • Unused procedures vanish automatically on compile.

      When I compile or debug the program I want all unused procedures to vanish automatically. (example: Private Sub TextBox1_TextChanged(sender As Object, e As EventArgs) Handles TextBox1.TextChanged End Sub should vanish when debug/compile if no code is inside it.)
      This worked in VB6.

      • Add IntelliSense for XML Literals based on Imported xmlns

        The current feature that allows you to import an xmlns gives IntelliSense only when consuming XML via XElement or XDocument objects. You can type .< or .@ or ...< after an objcect of type XElement or XDocument and get IntelliSense for the available element and attribute names based on the XML Namespace.

        I've spoken at several user groups and code camps on this subject and the next thing that everyone wants to do is to get IntelliSense when composing XML Literals, but that's not currently available.

        Even if you have an xmlns imported and type something like the following, you…

        • enable line comments in VB after the line continuation char (_)

          Just a very simple thing:

          I had an attribute and a field written on two lines like this:

          <DebuggerBrowsable(DebuggerBrowsableState.Never)> _
          Private _SomeField As String

          and wanted to add a line comment after the '_':

          ...State.Never)> _ 'My reason why

          I now get the following error: "Line continuation character '_' must be preceded by at least one white space and must be the last character on the line."

          My request now is to change the rule "...must be the last character on the line" to "...must be the last non-white-space character on that part of the line that does not belong…

            Hey Chris,

            Excellent suggestion! When we introduced implicit line-continuation in VB2010 it was a very painful restriction that we had to leave in due to technical and schedule constrains that comments weren’t allowed after them. Happily, thanks to the improved parser architecture we use in Roslyn (a future version of VB/C#) we will be able to support it one day. In fact, in the Roslyn compilers comments are already supported after implicit line-continuation so I can write this:

            ’ Comment here

            Private _SomeField As String

            After we got that working it seemed reasonable to lift the restriction on normal, explicit line-continuation as well though we haven’t yet done so.

            While we do not currently have plans to address this issue in the next release of Visual Studio, we are reviewing suggestions now for future versions of VB in and beyond the Roslyn time-frame. We have not determined when that will…

            • [Planned] Make 'References' node visible in VB projects in Solution Explorer (like C#)

              In C#, references are visible in Solution Explorer/Navigator. In VB you have to hide invisibles to achieve this.

                Good news everyone!

                We’ve fix this for Visual Studio “14” and verified that the node is visible on our internal builds. I’ll update this suggestion when you can see the change in a public release.

              • New syntax to map interface members to the base class

                Explicit interface implementation in VB makes the code much better readable and maintainable than C# code with its implicit (i.e. hidden/secret) interface implementation.
                It is one of the main advantages of VB over C#.

                However there is one drawback: If a class implements an interface, all interface members have to be implemented directly in that class.
                There is no way in VB to map an interface member to a member of the implementing classe's base class.

                In C# this works implicitly without any extra code. In VB, of course, we want to maintain an explicit way to achieve it.
                A…

                • Add NotifyPropertyChanged attribute (or keyword) to properties declared as auto-implemented properties

                  I absolutely love using auto-implemented properties and the removal of the need to declare a backing variable.

                  Public Property MyProperty As String

                  However, for classes that implement INotifyPropertyChanged, I can't use auto-implemented properties, and instead have to write the more verbose:

                  Private _myProperty As String
                  Public Property MyProperty As String
                  Get
                  Return _myProperty
                  End Get
                  Set(value As String)
                  _myProperty = value
                  RaiseEvent PropertyChanged(Me, New PropertyChangedEventArgs("MyProperty"))
                  End Set
                  End Property

                  Multiply this by a few dozen properties, and this gets a little tedious (even with code snippets), much too verbose to read, and increases the surface area for typo bugs.

                  I…

                  • Add some Tutorial Projects

                    Add some tutorial projects for those poeple who are new to vb.net/2011 get to know what it is and how it works n stuff encouraging them to get into programming and explore new ideas also making the process user friendly. The easiest way to do this by using sample projects like "HelloWorld" and implementing into vb as a tutorial project with basic fucktion like If Fucntions , Select Case and loop functions etc... basically Add more of some practical related tutorials :)

                    • Do Not Collapse Comments

                      It would be nice if the comments simply did not collapse with CTRL+M+O. That or if there is a blank space between two blocks of comments. Do not treat them as 1. But instead it will collapse the entire section even though comments may not be a part of the one above it (obv limitation of VB because they do not have multi-line comments). I'm sure if we could just have a more robust commenting system. Things would have been peachy and I may not have switched to C#.
                      This should be simple, and to me already done as the…

                      • One Line Initialization

                        I have a suggestion for a possible syntax improvement in visual basic.net. It's towards the initialization portion of a one line multiple declaration. Here is an example:

                        'Syntax:
                        Dim a, b, c As Integer = 5

                        'Output:
                        'a = 5
                        'b = 5
                        'c = 5

                        Attached is a file of an example where I would want to use a one line initialization. Take a look at the test scores(test1, test2, test3). An easier way to declare those would be:

                        Dim test1, test2, test3 As Double = -1

                        • The idea: "Visual Basic".

Mobile, WinRT, WinForms, Web, Installers, images and other media files, help files, reports and charts.

This time, the IDE must be purely for the VB language.

                          • Allow the subject of a With block to be referenced in the block using a new keyword WithRef

                            Primarily, this is a convenience mechanism to avoid having to declare a variable in certain cases.

                            Proposed:

                            Function ReturnNewCheese(cheeseType as CheeseEnum) as Cheese
                            With New Cheese
                            .CheeseType = cheeseType 'property
                            .Curdle 'method
                            Helpers.DoSomethingWithCheese(WithRef)
                            Return WithRef
                            End With
                            Exit Function

                            Now:

                            Function ReturnNewCheese(cheeseType as CheeseEnum) as Cheese
                            Dim x as New Cheese
                            With x
                            .CheeseType = cheeseType
                            .Curdle
                            Helpers.DoSomethingWithCheese(x) 'requires explicit variable declaration
                            End With
                            Return x 'requires explicit variable declaration
                            Exit Function

                              Hi guys,

                              I want to point out some flaw opcodes that vb compiler create and hope VB dev team have sometime to fix those and make VB better performance.

                              1. Array

                              When I create an array like this "Dim Data(input.Length - 1) As Char", compiler will rewrite to "Dim Data(input.Length - 1 + 1) As Char"; it's unnecessary 4 bytes and you loss 4 of 64 bytes if you aim to create a tiny method.

                              2. Function local variant

                              VB function away has self local variant like "Function foo() As string" will have "Dim foo As String" even it's unused…

                                • Collection initializers for read-only collection properties in VB.NET

                                  I'm very happy that Microsoft is committed to VB.NET have the same features as C#.
                                  One feature I use extensivle in C# is collection initializers. I've just noticed that VB.NET supports these but not for read-only class properties.
                                  I found at http://msdn.microsoft.com/en-us/library/dd293617.aspx that if a collection has a an Add method, it is used to initialize the variable. This should also apply to read-only collection properties.

                                  Here is compilable C# code showing the feature working:

                                  using System;
                                  using System.Collections.Generic;

                                  namespace ConsoleApplication3
                                  {
                                  class Class1
                                  {
                                  private readonly List<Int32> list = new List<Int32>();

                                  public List<Int32> ListProp
                                  {
                                  get
                                  {
                                  return this.list; …

                                  • Extend for each loops to be able to handle Linq clauses (eg. where, order by)

                                    At the moment, we have to use 2 lines to do the following...

                                    Dim ps = From p in People Where p.Active=True Order By p.Surname, p.FirstName

                                    For Each p In ps ...

                                    It would be neater to be able to write code such as

                                    For Each p In People Where p.Active=True Order By p.Surname, p.FirstName

                                    I don't see why this can't work with C# too.

                                    • Add to Visual Basic the ability to declare a new strong type in terms of another type

                                      Many other languages have 'strong' typing. Java, C#, and VB have strong typing regarding classes, but not for the primitive numeric types. It can be a great aid to making large-scale industrial and commercial software. For example, if one could declare two different types Apples and Oranges:

                                      Type Apples Is New Integer
                                      Type Oranges Is New Integer
                                      ...
                                      Dim A As Apples = 3
                                      Dim B As Oranges = 4

                                      then accidentally mixing arithmetic or assignment between these types would be prevented by the compiler, e.g. the assignment:

                                      A = B

                                      would be rejected by the compiler (and Intellisense) as…

                                      • Allow multiple languages (C#,VB,F#) in the same project

                                        Now with Roslyn this could be possible.

                                        It's very annoying that you have to convert C# to VB just to include a class/function/snippet in your VB project, and viceversa.
                                        If all code compiles to MSIL, then why we cannot use different NET languages in the same project.

                                        Another example is a function in F#, you may want to use some functions that will simplify/improve your project (C#/VB) and it's better to do it in a functional language, but you don't want to code all your project in F#, nor want to create a separate project in F# with its DLL…
