• Red Gate to continue development of .NET Reflector

  .NET Reflector, by Lutz Roeder, must be one of the most useful tools I have when developing .NET code. Usually it is the first thing I install right after Visual Studio not even waiting until I need it because I know I will. So the big news is that Red Gate, makers of the Ants profiler and lots of other tools, are taking over from Lutz Roeder and will continue developing .NET Reflector. Interesting move and I hope this means a bright future for the .NET Reflector. Read more about this here . Enjoy! www.TheProblemSolver.nl Wiki.WindowsWorkflowFoundation.eu Read More...

  Steve Lasker just announced that SQL Server Compact 3.5 service pack 1 is released, read his announcement here . They added support for the entity framework, great stuff. And another neat feature is native 64 bits support. No longer do you need to target X86 and use WoW [:0]. Great if you are using my SQL Server Compact Workflow Persistence Service . Enjoy!

• CodeCamp 2008

  Afgelopen jaar hebben we het eerste CodeCamp in Nederland georganiseerd en dat was een groot succes. De meeste deelnemers vroegen om meer, sommige zelfs om een CodeCamp per kwartaal of een heel weekend lang. Nou hebben we dat laatste nog niet gedaan maar we zijn wel aan de slag gegaan om een nieuw CodeCamp te organiseren. Als datum hebben we zaterdag 6 september gekozen. Gelukkig waren Microsoft en Class-a behulpzaam en kunnen we, net als vorig jaar, weer in het Microsoft Innovation Center in Barneveld terecht. Een mooie datum en locatie om uitgerust van de vakantie een hoop kennis uit te wisselen. Het programma staat nog niet helemaal vast, hou daar de website voor in de gaten, maar je kan er ondermeer de bekende Nederlandse sprekers verwachten. Uiteraard kan je zelf ook nog een sessie voorstellen dus als je een idee hebt voor een leuke sessie laat het dan zo snel mogelijk weten. Dus zet de datum vast in je agenda en meld je zo snel mogelijk aan op de website www.code-camp.nl . Het CodeCamp is een gezamenlijk initiatief van de SDN , de stichting DotNed en VB Central .

• How to Download all of Visual Studio 2008 SP1

  VS2008 SP1 Beta is quite a package. By default the installation downloads the packages as needed and when needed. Now that is just fine if you only need to install a single machine. But when you need to install multiple, possibly virtual, machines like I have to it just wastes a lot of bandwidth and time . Fortunately there is a solution and it can be found here in the blog post by Heath Stewart. Enjoy! Read More...

• LINQ to SQL and creating databases

  LINQ to SQL has a really nice feature when making sample and demos in the ability to create the database if it doesn't exist yet. It also has a function called DatabaseExists() to check if a database exists. Both are defined on the DataContext class. string connectionString = @"Data Source=.\sqlexpress;Initial Catalog=MyNewDatabase;Integrated Security=True" ; MyNewDatabase context = new MyNewDatabase (connectionString); if (!context.DatabaseExists()) context.CreateDatabase(); And best of all they work both for SQL Server and for SQL Compact so it is real easy to make demo's that work with both the full SQL Server as well as the lightweight SQL Compact. All you need to do is change the connection string. connectionString = @"Data Source=MyNewDatabase.sdf" ; Now I specially like the SQL Compact option for samples as there is no installation requirement, just copy the files and you are good to go . In fact I have been using LINQ to SQL to create a SQL Compact Workflow persistence service but because of the very nature of LINQ to SQL I can use it just as well with the full blown SQL Server as SQL Compact. So why do I consider the DatabaseExists() function only suitable for demo's? Well in the case of SQL Server it makes a connection to the server and sees if it can use the database. Hardly a very reliable check as it can fail for any number of reasons. And if the database exists it still doesn't mean that the schema is correct. For SQL Compact the Read More...

• On the WF ReceiveActivity and WCF bindings

  The new ReceiveActivity and SendActivity that marry Windows Workflow Foundation (WF) and Windows Communication Foundation (WCF) are really cool . Getting started is easy because a new Sequential Workflow Service Library, found under WCF instead of Workflow in VS2008, uses nice defaults for everything. But sooner or later you need to change these defaults and you need to know what can be done and what can't. When you want to use the new ReceiveActivity in a workflow you need to use a compatible WCF binding. The reason for this requirement is that the conversation context, see this blog post , is part of the message and needs to be retrieved and returned. The following code returns a list of all WCF binding and how they are composed: Sub Main() Dim assemblies As New List( Of Assembly)() ' .NET 3.0 assemblies.Add( GetType (ServiceHost).Assembly) ' .NET 3.5 assemblies.Add( GetType (WorkflowServiceHost).Assembly) assemblies.Add( GetType (WebServiceHost).Assembly) Dim query = From assembly In assemblies _ From type In assembly.GetTypes() _ Where type.IsSubclassOf( GetType (Binding)) _ AndAlso Not type.IsAbstract _ AndAlso type.IsPublic _ Order By type.Name _ Select type PrintBinding(query.ToList) Console.ReadLine() End Sub Private Sub PrintBinding( ByVal types As List( Of Type)) For Each type In types Console.WriteLine(type.FullName) Try Dim binding As Binding = _ CType (Activator.CreateInstance(type), Binding) Dim elements = binding.CreateBindingElements For Each element Read More...
