Poster do .NET Framework 4.0

Durante o PDC que rolou lá nos “States” esta semana, a Microsoft liberou a primeira versão preliminar pública do .NET Framework 4.0, Visual Studio 2010 e os planos sobre um monte de outras coisas como o Windows Azure, Windows 7 e por aí vai.

Eu já estou com a minha VM do VSTS 2010 aqui, mas ainda não tive tempo de mexer muito com ele.

A primeira coisa que percebi foi que a Start Page parece ser feita com WPF. Estou bastante curioso para ver o que vem no C# 4.0.

Eles também lançaram um poster sobre as novidades que vieram com a SP1 do Fx 3.5 e o que deve vir no 4.0.

Você encontra uma versão online usando Deep Zoom aqui.

Tem um monte de vídeos a respeito disto tudo lá no Channel 9 .

Bem legal!

Dependency Hell – Or Compilation-time DLL Hell

For the last couple of months I’ve been working on a project on which the entire Visual Studio solution has 65 projects.

Luckily I’ve been able to work with a smaller solution with only a subset of the projects: The ones that I was working directly with and the ones that I needed for a reason or another.

Unfortunately a couple of weeks ago, the time to start integrating my projects to the main solution arrived and since then I and other team members have been having troubles setting up references between projects.

I ended up detecting that the problems where caused by the references being set by file when for the sake of easy compilation they should been referenced by project.

I then reviewed all the projects setting their reference types to project references and the number of issues fell dramatically.

But occasionally a team member was getting compilation errors during to version number conflicts.

Imagine that project A depends on projects B and C and that B and C depend on different versions of D.

When you try to build the entire solution, although references where set to projects instead of files, Visual Studio 2003 couldn’t compile project A stating that there where conflicting versions of D in the bin folder.

Well, to get the story short, after trying to get rid of the error I searched around and ended up finding an article the explained how to resolve the issue: Error: the dependency ‘file’ in project ‘project’ cannot be copied to the run directory because it would conflict with dependency ‘file’
