  Hello, I am having the most difficult time trying to deploy a web service created with Visual Studio 2005, Beta 2.  I'm hoping that I'm just missing one small detail and that someone can point it out to me.

• ncjks Two-way communication using IPC

  Hello, I've been reading up on IPC and looking at sample code, and I can't seem to figure out how to actually accomplish communication from a client to a server. I understand the concept of a server hosting a dll which contains a method that the client can call. However, how can the server also obtain a reference to the same object I want the client to be able to send a message that makes it to where the server can use it. To clarify my question ...Show All

• RADIOGENERIS Web Services .net framework 2

  I have just ported an ASP.NET 1.1 application to framework version 2 and i have a problem.

• Greg Walker Beginner: Q on using XSL to convert from XML to XML

  My first time dealing with XML/XSLT I have to take a XML file(that is HUGE), and convert it into another XML format (the purpose being to get rid of most of the unwanted information and retaining just the ones our program needs) I was told that I can do this easily using XSL.

• ThomasD Assemblies, Versioning, etc....

  Okay Here I go... I have a program which loads a bunch of DLLs at startup and uses them during the program. When the user serializes a file it uses the information from those DLLs. If I make any changes to the DLL then recompile the program that file will no longer load up because it is referencing the old DLL. So I need to make those old DLLs look at the new version of the same DLL (granted the new DLL has similar features to the old DLL). ...Show All

• Chris Bernholt Why all the sealed classes

  what is with classes in the .net runtime being sealed. It is understandable that some classes such as security and like are sealed but it beats me why you would seal a ConnectionStringConfigurationSection class. Why researching on how I could create a more 'aware' connection string configuration whilst still leveraging the existing ConfigurationManager.ConnectionStrings method used by local and third-party components alike I discover that t ...Show All

• audigger Why does the 64Bit section exsist?

  As I understand the .Net framework there shouldn't be any issues for any code compiled in MSIL runing on a 64Bit system. So why does this section of the forum exist In addition although C# (and other .NET languages) can be configure to create "agnostic" assemblies, this is not the only option.
