• Enterprise Library 3.1: Enterpise Library Configuation Editor Problem

An application I was working on needed to run on with the Entiprise 3.1 Library.  When I tried to use the Enterprise Library Configuration editor (EntlibConfig.exe) on my app.config file, I was getting errors that it could not locate the specific libraries/.dll’s.  The problem was that my libraries in my code where strongly named (PublicKeyToken=b77a5c561934e089) while the Enterprise Library Configuration Editory was looking for libraries with the PublicKeyToken set to null (PubliKeyToken=null).  The fix was to use the RIGHT Enterprise Library Configuration editor.  There are two of editors.  One resides in C:\EntLib3Src\App Blocks\bin and the other resided in  C:\Program Files\Microsoft Enterprise Library 3.1 - May 2007\Bin.  The former works with non-signed libraries while the latter works with signed libraries.  From the Visual Studio Development environment, I changed app.config editor to point to the C:\Program Files\Microsoft Enterprise Library 3.1 - May 2007\Bin editor.

  • From Scott Mitchell's blog, I found out about a product called ELMAH that may come in handy down the road.  ELMAH (Error Logging Modules and Handlers) is an application-wide error logging facility that is completely pluggable. It can be dynamically added to a running ASP.NET web application, or even all ASP.NET web applications on a machine, without any need for re-compilation or re-deployment.

  • The table designer in Microsoft SQL 2005 I find is lacking because I cannot find a way to add properties to the columns displayed.  It only displays Column Name, Data Type, and Allow Nulls.  From Rich Strahl's Web log, comes a work around.  Use the Database Diagram Designer.   Right mouse click on the Database Diagrams folder and click New Database Diagram.  Next add your table.  Right mouse click on the table-->Table View-->Modify Custom...
