One of the features I use often with the Microsoft Web Service Enhancements (WSE) is logging. It's a great feature where it logs everything coming in and out of a web service. When someone calls me with issues, the first thing I do is turn this on in the web.config and watch the data coming and going. The data is stored in two different xml files. One for incoming calls and one for responses.
The problem I just ran into is that I got a call that stated web service calls that were taking about 1 second or less were now taking 20 seconds or even timing out. After working on the issue off and on for two days I discovered that these two WSE log files have grown to 59MB+ because I forgot to turn off logging the last time there was an issue! Once I turned off logging this issue went away.
One symptom that we noticed that made us go down the wrong direction at first was that the w3wp.exe in Task Manager would eat a lot of memory during those 20 seconds and spike the CPU usage up to 99%! When we Googled this, we found lots similar issues, but none relating to the xml log files generated by WSE. We wasted a lot of time on this.
I hope this helps anyone else that uses logging in WSE.

If you are a student at a university, you can get a free copy of Visual Studio 2008 Professional and other Microsoft software. Got to this link: https://downloads.channel8.msdn.com/Products/Visual_Studio_2008.aspx
The ASP.NET 3.5 Extensions Preview is a preview of new features being added to ASP.NET 3.5 and ADO.NET.
I found out the hard way in the last two days that an SQL Server CE database does not work properly when creating a typed Dataset with a ASP.NET 3.5 application. Sure, you can create one in the IDE, but the code-on-the-fly will not be generated therefor you can't use it in your code. Actually causes an error if you try to build.
Rec'd an confirmation from Microsoft today that they did not implement this for ASP.NET. Just wanted to warn you so you don't waste an hour plus like I did. If you still want to use SQL Server CE and typed DataSets in ASP.NET you will need to create a separate assembly (which should be done anyway). Oh, won't work with LINQ either.
I needed to update a program and when I brought it up in VS 2008, it changed the version of Crystal Reports to 10.5.3700. This presented a challenge to get the required Crystal files onto the production server. Of course using the VS web publish feature does not do this even though I wish it did. So I went to the Business Objects site (makers of Crystal Reports) to search for an install. I first download the version for 2008... made sense to me, but it actually turned out to be version 12.
Then I tried the download for CrystalReports 2008 ClickOnce Package for Visual Studio 2005 since it said it was version 10. Unfortuneatly it did not say what minor version it was. This turned into a headache because it kept asking me for a product ID before the install would continue. I followed the instructions and got the number from VS 2008 and that did not work. Even spend time registering Crystal with Business Objects and that did not work either. I tried to create a support case on their web site and that was not even working!
After many hours of frustration, I did a search of my hard drive of ANY file that started with "Crystal" and I finally found it! The installs are located in this directory:
C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bootstrapper\Packages\CrystalReports10_5
The files are either CRRedist2008_x86.msi or CRRedist2008_x64.msi. I installed them on the server and everything worked fine.
I hope this might save you from all the the wasted time I went through. Another reason why I love Microsoft Reporting Services!!!

I hope everyone in southern California is planning to attend this years SoCal Code Camp up at Cal State Fullerton on 1/26 -1/27. It's always a great time and lots of free training! My fav southern California band Killola will be playing again at the Geek dinner so make sure you arrive early on Saturday to grab one of the limited number of tickets available.
I will be doing the following sessions and I hope you will attend.

Often, it's a good idea to make sure the user trying to access the file has permissions to it before performing an operation like read, write or delete. Below is code that makes this pretty easy.
Sub DemandFileReadPermission(ByVal fileName AsString)
If System.IO.File.Exists(fileName) Then
Dim filePermission AsNew System.Security.Permissions.FileIOPermission(System.Security.Permissions.FileIOPermissionAccess.Read, System.Security.AccessControl.AccessControlActions.View, fileName)
filePermission.Demand()
EndIf
EndSub
Sub DemandFileWritePermission(ByVal fileName AsString)
If System.IO.File.Exists(fileName) Then
Dim destinationFilePermission AsNew System.Security.Permissions.FileIOPermission(System.Security.Permissions.FileIOPermissionAccess.Write, System.Security.AccessControl.AccessControlActions.Change, fileName)
destinationFilePermission.Demand()
EndIf
EndSub
One warning though... performing a permission .Demand takes time. In a quick test on my machine it was a pretty consistent 10 milliseconds. So you might not want to do this all of the time.
