• SureshJayaraman SecurityAction.DemandeChoice is obsolete ?

  I'm working with Beta 2 (v2.0.50215) and I'm using PrincipalPermissionAttribute. As I wished to use more than 1 attribute on a single method, I tried the new SecurityAction.DemandeChoice flag. To my surprise, the compiler said this flag is obsolete ! I've not found anything about that on the web (nothing about that on MSDN2 for example) except in a Mono mailing list. Has this new feature been removed Is there other removed feat ...Show All

• STLL How to create not-documented, non-re-usable components

  Avoid writing XML comments! These comments are readable from the developers that use your components. Intelli-sense is the worst enemy of your cause. Avoid using Roland Weigelt's GhostDoc . It can help you write XML comments making your components have intellisense support. Also avoid NDoc . This infernal tool can create MSDN-like documentation for your component. Never, never, never, never, NEVER create samples to demonstrate how to use your ...Show All

• BrunoCO generics and Marshal.Sizeof, PtrToStructure

  Hi, I had written some code that was using the Marshal class together with generic classes and it worked fine under the .Net 2.0 Beta 2. Now I recompiled with the Studio 2005 release version and ran it under the 2.0 Release, and suddenly it throws an ArgumentException. Indeed the documentation for Marshal.SizeOf says (in the release version, not in the beta version!) that the function (more precisely, the overload that accepts a t ...Show All

• salim_555 Unmanaged application using managed library can't find referenced assemblies

  There's a C# application with some DLL's. There's an unmanaged application (Total Commander) and I want to create a plugin for it that uses some functions from my C# libraries. I figured the best interface is a managed C++ library: it implements the unmanaged plugin interface by exporting the necessary functions, and it calls into my managed code, so I don't have to reimplement that library. Problem is, it can't find the referenced assemblies (F ...Show All

• cmag1951 .NET 1.1 in Visual Studio 2005

  I'm sure this might be a dumb question, but I thought I'd go right to the groups to hopefully get a quick explanation. I'm writing a client app in VS 2005 that references a web service I had written in VS 2003. The client app utilizes 2.0, the web service uses 1.1. I know that the two can communicate, but can I pull the web service project into the VS 2005 solution and still it will rely on 1.1 (because the hosting server is only 1.1 capable). A ...Show All
