.NET Forum / Visual Studio.NET / IDE / May 2004Name conflict in solution
Hi group, (VB.Net 2003) in one solution, there are two WindowsApplication projects. They don't have a relation to each other (are no classlibraries). In the solution properties, there are no dependencies either. When compiling one project I get the following error: g:\bla\calendar\Form1.vb(1): class "Form1" and class "Form1", defined in "G:\bla\WindowsApplication3\Form1.vb", conflict in Namespace "WindowsApplication3". (roughly translated from German) The solution is stored in g:\bla. project 1 in g:\bla\calendar project 2 in g:\bla\WindowsApplication3 Project 2 is the only startproject in the solution. After searching for the reason of the error, I found out that project 1 ("calendar") had the same root namespace as the second (both "WindowsApplication3"). BTW, both are not "real" projects, only for testing. Q: Why mustn't the projects have the same namespace? They don't have to do anything with each other. What does the compiler want to "link" together? Is there an explanation for this?  SignatureArmin They can have the same namespace, but youn can't define two or more classes with the same name within a single namespace. How would the compiler know which to choose?

How would the > compiler know which to choose? The other class is in a *different* project. The projects have no relation to each other. SignatureArmin Anybody? Steps to reproduce: 1. Create new Winforms project 2. Add new Winforms project to the same solution 3. Set root namespace of 2nd project equal the one of the 1st project In VB.Net: error, Form1 defined twice (not only in the tasklist, also when building one of the projects). That's not ok because they are completeley independent projects! Same steps done in C#: No error! That there is no error in C#, as expected, shows that it must be a bug in the VB.Net integration. SignatureArmin How to quote and why: http://www.plig.net/nnq/nquote.html http://www.netmeister.org/news/learn2quote.html Yep, you're right, looks like a bug. I guess most people don't set them to the same value. I can see it in VS 2003 but not in my build of VS 2005 so looks like they already fixed it there.
