I knew from here that we have to do the explicit imports for child namespace because imports will not include the child namespace.But my question is that if I do "imports System" whether it will include all the classes/methods inside that namespace in the IL/native code or only referred ( used inside the application) will be included in the IL/native code.
View 1 RepliesIn my Solutions in Visual Studio, I have 3 projects.
- Common (Root namespace: PodcastPlayer.Common)
-PodcastPlayer (Root namespace: PodcastPlayer) This is the Silverlight project.

In Common, I have several classes and service references.But my problem is that I can`t not use PodcastPlayer.Common namespace in PodcastPlayer project.

View 2 RepliesI'm setting up a simple XML read-write demo (VB Winforms) in Visual Studio 2010 Premium (tried in both the RC and RTM) and added:
Imports System.Xml
Result: Error Namespace or type doesn't contain any public members or cannot be found...
VS 2008 equivalent example recognizes the Imports statement fine.I know this has to be me, but I'm stumped.
Note: I tried this with the app targeting both .Net 3.5 and 4.0. Same result.
I have a WPF VB.NET project in Visual Studio 2008. For some reason, Visual Studio thinks that it needs to add anImports MS.Internal.Xaml.Builtinsto every auto-generated XAML partial class (= the nameOfXamlFile.g.vb files), resulting in the following warning:warning BC40056: Namespace or type specified in the Imports 'MS.Internal.Xaml.Builtins' doesn't contain any public member or cannot be found. Make sure the namespace or the type is defined and contains at least one public member. Make sure the imported element name doesn't use any aliases.I can remove the Imports line, but, since this is an auto-generated file, it reappears every time that the project is rebuilt.

I've started to use a Vista machine for development. In case it is significant: I'm using MSBee so that I can code in the Visual Studio 2005 IDE while still building against the 1.1 framework.On the Vista machine, when I tried to build a particular vb project, I got this error:
error BC30464: Namespace or type'Compatibility' in the project-level Imports 'Microsoft.VisualBasic.Compatibility' cannot be found.
The same project built fine on my old XP machine. I checked in this folder on my Vista machine:
C:windowsmicrosoft.netFrameworkv1.1.4322
...and sure enough, "Microsoft.VisualBasic.Compatibility.dll" was missing. So was "Microsoft.VisualBasic.Compatibility.Data.dll". Copying them from my XP machine to my Vista machine allowed me to build the project successfully.I'm just a bit puzzled as to why this happened. Why was "Microsoft.VisualBasic.Compatibility.dll" missing? I'm also not very comfortable with my chosen solution - copying the DLL manually. It works, but surely there must be a better way.
As far as the configuration:
Vista:
.Net Framework 1.1
.Net Framework 1.1 SP1

View 2 RepliesThis class is located in the namespace Acme.Infrastructure.Interface.A class with the same name EventArgs exists in the System namespace.In another project in my solution I have a class Acme.BusinessModules.MyModule.MyClass.When attempting to use the EventArgs class I have to fully qualify the class name or the compiler thinks I am using the System.EventArgs class.My understanding of namespace resolution was that the compiler would first look for the class in the current namespace, and then its parents. It seems that the compiler checks in System before it checks in sibling namespaces. Is it correct that System is checked before the sibling? Or is this behaviour caused by other issues (Imports order?)?

View 2 RepliesI have a function when fired queries against the database (twice) and returns the results in a dataset. It checks the results (to make sure there are some) then loops through and grabs each row from the returned dataset and imports (copies) it to a different dataset.I also add a primary key into a List so I do not add the same item twice (from the 2nd query) to the dataset.I then return the dataset.The problem? The query works and there is a returned value.. however the dataset in which I aim to import the row(s) to does not keep the imported row.

I have never used LINQ before, and I am getting an error in an application that does use it. This is a VB.NET (.NET 2.0) project in Visual Studio 2008.
Here is the offending code:
Dim orderedRows = From r In resultRows Order By r.FIELDNAME Select r
And here is the error (names changed to something generic, but otherwise accurate):
Expression of type '1-dimensional array of
Company.OurLibrary.FunctionalArea.Library.StoredProcStuff.USP_MYPROC.ResultRow'
is not queryable. Make sure you are not missing an assembly
reference and/or namespace import for the LINQ provider.
C:projectfilename.vb
So I recognize that I need to import LINQ libraries. This link led me to add "Imports System.Linq" to the file, but that is an unresolved reference. Based on the same link, I figured I needed to add a reference to "System.Core" to my project, but it is not listed as an available option when I try to add a reference (nor is it already checked).
a common VB.NET class should look like the following:
Public Class MyClassName
End Class
Besides, I have already seen, if I remember correctly, all of the import statements visible just like in C#:
Imports System
Imports System.Data
Imports System.Linq
Public Class MyClassName
End Class
How to make these default imports visible by default in VB.NET using Visual Studio 2008?Is there some setting or the like in the options I shall set?
