• 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...

• SQL Server Compact 3.5 SP1 released

  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 .

• SQL Compact 3.5 on a 64 bit Windows

  SQL Compact is a great little database and highly recommended. However it was designed for use on small compact, hence its name, devices and that has some drawbacks. One of these is that it doesn't run as a 64 bits application. And by default if you create a .NET application it is compile as "Any CPU" meaning it will run as a 64 bits application on a 64 bits version of Windows. I, or I should say Ron Jacobs , ran into that using my SqlCeWorkflowPersistenceService because the sample/test application was set to the default of "Any CPU". The result is that the LINQ provider cannot load the runtime and a InvalidOperationException with message "Cannot open 'WorkflowPersistenceDatabase.sdf'. Provider 'System.Data.SqlServerCe.3.5' not installed." is the result. Now the fix is rather easy but it has to be done in the main program and that is to compile it for X86 instead of Any CPU. Do this and any application using SQL Compact 3.5 will happily run on Windows 64bit as a WOW Application. Enjoy! Read More...

• SQL Server Compact Workflow Persistence Service updated

  I have just updated the SQL Server Compact Workflow Persistence Service to better handle deserialization issues when loading a workflow. The service now makes sure the WorkflowRuntime ServicesExceptionNotHandled is raised, something it should have done in the first place. You can download the SQL Server Compact Workflow Persistence Service from here . Enjoy! www.TheProblemSolver.nl http://wiki.WindowsWorkflowFoundation.eu Read More...

• FaultHandlerActivity and workflow persistence

  I was just working on an issue reported against the SQL Server Compact Workflow Persistence Service I released some time ago. It turns that if you are using workflow persistence your workflow will actually be persisted to the store when an exception is caught. Now in itself not a big problem as your whole workflow needs to be serializable anyway. Except this time where is an additional exception object and when the exception itself cannot be serialized this brings the whole workflow down. In fact it brings more that just the workflow as the whole workflow runtime crashes, not good The culprit in this case was a SqlCeException which is not serializable! Don't worry about the more common SqlException because that is perfectly ok. Still something to double check as these exceptions are, by their very nature, the exceptional case and therefor less likely to be tested.

• 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...
