My .Net Blog

Visual Studio 2010 is in the market for a little while. That sounds like no opensource alternative for .Net 4.0 until now. SharpDevelop 4.0 Beta 1 is released. I have tried that. So far, my first impression is slower. I guess that is because the UI is heavy rewritten in WPF. I think most of people will agree WPF got a better appearance and runs slower. But it got a feature I want for long time. Windows forms designer for WPF. Now, you can use the form desginer to edit xaml. That's great! By the way, in release notes, they do not recommend to use the form designer for editing .net 2.0 winfrom files. I tried that, so far, I have not faced any major issues. Well, they don't recommend that, I think you should not do that.

Lastly, so far, I am very happy to the new version. It looks better and got more features!

I have been asked to build a library management system for my church. That is very very simple system. The system only needs to track the borrow records. I don't think that even needs a database. Orginally, I planned to use serialization for storing the records. But if in future, they want the records to be viewable on our church website as well. Then I need to port the records to the database and change the application to use a database. OK, maybe, that is good to install mySQL in the computer. Well, that is too over-kill the resources. So, I found Sqlite. It can relpace the flat system to store the record. Moreover, it has an ADO.Net driver and is fully supported by NHibernate. In the future, I can port the codes to another database technology by changing database driver in NHibernate. Finally, I chose Sqlite as the data storage.

MonoDev is getting well developed. Now, it has an ASP.Net Toolbar and even it has database explorer!

I am writing a program for myself by using ActiveRecord. I am an MS SQL Server Develper. So, I just did in a careless mistake. I called a table , User. If you call a table will crash with system table name, we use '[' and ']'. I hardcoded the table name in '[User]' in a Model class for ActiveRecord. I can't create a schema by Active Record. Because in MySql, we use '`'. So, it should be
