System Namespace Conflict With Sibling Namespace
Nov 16, 2011This 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 RepliesImports System.Xml - Error Namespace Or Type Doesn't Contain Any Public Members Or Cannot Be Found?
May 2, 2010I'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.
Warning 1 Namespace Or Type Specified In The Imports 'System.Windows.Forms' Doesn't Contain Any Public Member Or Cannot Be Found
Mar 14, 2010When trying to compile my newly created ClassLibrary class 'Validator' that validates entries made into TextBoxs or MaskedTextBoxs, I get the following error:

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.

What can I do to resolve this problem? The classes in this class library will be used to validate forms data input in a number of varied projects.

View 11 RepliesSearch Namespace For Generic Type (Reflection)
Sep 27, 2010I'm attempting to dynamically register entities and configurations with a context (ef4 code-only). I would normally do:
Private Shared Sub ConfigureDatabase(ByRef Builder As ContextBuilder(Of ContextExtension))
'Load configurations for each of the tables (Entity sets) in our database...
ConfigureEntity(Builder, New ContactConfig)
End Sub
Private Shared Sub ConfigureEntity(Of T)(ByRef Builder As ContextBuilder(Of ContextExtension), ByVal config As EntityConfiguration(Of T), ByVal setName As String)
'Register the entity configuration with the builder
Builder.Configurations.Add(config)
'Register the entity set name with the builder
Builder.RegisterSet(Of T)(setName)
End Sub
Where ContactConfig is a class which inherits EntityConfiguration(Of Contact) and Contact is a class which implements an interface IEntity (IEntity is common to all entities). So... I need to search a namespace (say Project.DB.Client) for all signatures that match:
EntityConfiguration(Of <Class which implements IEntity>)
How can I achieve this?

ASP.NET 3.5 WebSite Stopped Importing System Namespace By Default
Apr 13, 2010I have a VB Web Site project that has recently (and mysteriously) stopped importing the "System" namespace by default.
I'm having to either place an Imports System line at the top of each code behind, or preface everything with System, which is fairly annoying, not to mention redundant. I can't for the life of me figure out how to get the System namespace back to being imported by default.
I've already checked to see that WINDOWSMicrosoft.NETFrameworkv2.0.50727CONFIGweb.config contains the <add namespace="System"/> line--it does. That was my best lead.
I have references to several namespaces within the System namespace in the <assemblies> node (e.g. System.Design, System.Web.Extensions of my website's web.config. There is no <namespaces> node. This has not been changed recently.
