I always tend to recompile assemblies when something changes they depend upon.
But now I’m even more careful after reading Fabulous Adventures In Coding : Putting a base in the middle.
Especially his checklist is important.
When you use a newer version of an assembly you depend on:
(1) at the very least test your derived types with the new base type — your derived types are relying on the mechanisms of the base types; when a mechanism changes, you have to re-test the code which relies upon that mechanism.
(2) if there was a breaking change, recompile, re-test and re-ship the derived type. And
(3) you might be surprised by what is a breaking change; adding a new override can potentially be a breaking change in some rare cases.

When you want to deploy WPF, it is important to check if you have sufficient hardware acceleration for your apps.
The most important things to check is the RenderCapability.
It gives you the Tier on which graphics is rendered.
The Tier tells something about hardware acceleration support, including a broad estimate of the pixel shader and vertex shader levels and DirectX versions.
Currently, there are 3 tiers: Read the rest of this entry »

After the excitement of .NET 4.0 and all the tools around it, I totally forgot to mention that SQL Server 2008 R2 got to RTM.
If you are an MSDN subscriber you can download it there.
If you are not, you can download the Microsoft SQL Server 2008 R2 RTM – Express with Management Tools.
Brent Ozar wrote a pretty nice FAQ on the new SQL Server 2008 R2 features, much better than the “what’s new” and press release by Microsoft.
Feature conclusion so far:
- nice new stuff for Business Intelligence
- no new stuff on the engine and T-SQL front
- watch your licensing when doing virtualization; the non-R2 is far cheaper for that

The Microsoft patterns & practices Developer Center released the Microsoft Enterprise Library 5.0 last week.
This version of the Enterprise Library has a ton of new features, and now has full support for .NET 4.0 and Visual Studio 2010.
Next to using it from C#/VB.NET, I’m looking forward to see how well this can be used from the upcoming Delphi Prism 2011 release (scheduled to be released on May 15th).
Lots of stuff to experiment with :-)

If you have a TechNet or MSDN account, you can download the SharePoint, Office, Visio and Project 2010 RTM builds.
Downloads have become available on April 23rd.
The SharePoint designer is available from the Microsoft Download centre as William Conrwill describes at CodeJedi.NET : SharePoint, Office, Visio and Project 2010 RTM are now available on MSDN.
If you have SA, then as of today (April 27), you can get your volume licenses as well.
William describes more dates in his post Office, SharePoint, Project and Visio 2010 have made RTM!
I’ll be busy playing with all the bits from Delphi and .NET API perspective :-)

I usually pick a fresh VM for installing an RTM build, but if you have loads of stuff on your (physical) machine, upgrading RC to RTM can be a real time saver.
Stack Overflow has a nice question Upgrading Visual Studio 2010 RC to RTM answered by Danny Thorpe (yes, two links: blog / wikipedia).
The order is really imporant, so lets repeat that here:
- Uninstall all the VS 2010 parts
- Uninstall the .NET Framework Multitarget package.
- Reboot
- Uninstall the .NET Framework client package
- Reboot

A client recently asked me what space should reserve to store URLs in their DBMS.
The plurality in the topic title is a hint: different systems have different limits on URL lengths.
But first:
Don’t use long URLs
If you use long URL’s (longer than say a coupe of 100 characters), then usually you have a problem.
First of all: short URL’s are easier to remember, index and search.
Second: long URL’s can pose problems.
It might be that your browser and server support them.
But a user might be behind an intercepting proxy (sometimes invisible to both you and your user) that imposes a URL limit.
In stead of long URLs with a HTTP GET, use shorter URLs with a HTTP POST. Read the rest of this entry »

Last week, I posted a C# implementation of the tee filter from Sterling W. “Chip” Camden.
Since then I have modified it slightly.
Not because the implementation is bad, but because some pieces of software play dirty when saving their redirected output.
One of those applications is SubInAcl, otherwise a great tool for showing and modifying ACL and Ownership information of Windows NT objects (files, registry entries, etc).
However, when redirecing output or piping it, it writes a zero byte after each byte of text.
I’m not sure why: it might try to face some Unicode output, or just be buggy.
The new sourcecode is below. You can also download the project and binary as tee.C#.7z (you need the freeware 7zip compression tool to decompress this).

Every major release of software will bring great new stuff, but the price of upgrading from a previous version is that some stuff will break.
.NET 4.0 brings a lot of nice stuff as well, but there are a few things that break.
There is a nice Breaking changes in .NET 4.0 – Stack Overflow article on this.
The article is now a community wiki, and refers to these pages:
Since the article is a community wiki, expect it to be updated over time.
I wonder what these changes will bring (and break) in the upcoming Delphi Prism release (the datasheet is out now, the product should be out before the end of may).

PS:
If you do not have an MSDN subscription, but still want to see if things break for you, try one of these:
Scott Guthrie has a nice post on the bells and whistles of VS2010.
