A logger is a very useful tool when developing a (web)application, especially when you’re using an object-relation mapping solution such as NHibernate or Entity Framework. In order to improve the performance of your application it is useful to analyze the SQL queries and other information (e.g. warnings, errors, caching) about the object-relation mapping.
Since NHibernate 3 it is possible to implement a custom logger. Log4net is not necessary anymore. In this post I’ll describe how to implement your own logger.
Most .NET 4 shared hosting providers offering their customers a medium trust environment. This is not a problem for most web applications unless the applications uses MySQL in combination with the .NET MySQL driver (MySQL.Data.dll). The MySQL driver connects to the MySQL database using a socket. However, sockets are not allowed in medium trust. The application will throw a SecurityException with the following message:
Request for the permission of type 'System.Net.SocketPermission, System, Version=18.104.22.168, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
Like in older versions of Visual Studio it is possible to use NUnit as an external tool in the new 2010 version. By creating a toolbar as well it is very easy to run your test suite. The usual way to add an external command is by clicking the menu Tools -> External Tools. However, by default this menu item is not visible. To enable this menu item go to Tools -> Settings -> Expert Settings.
