When learning a new ORM one of the most important and interesting thing is to get to know how you can manipulate data with that tool.Thus, this particular thing is explained in this tutorial.

If you use LINQ to SQL, you may wonder why Microsoft released yet another ORM (Entity Framework), while they already had one. You may also be confused, because it’s not obvious which one to choose. Anyway, the Entity Framework has its own shiny features that don’t present in LINQ to SQL

Although MySQL don't seem to be very interested in providing a native support for LINQ to MySQL and you have to use 3-rd party providers to interact with MySQL by using LINQ, they seem to move towards Entity Framework.

I've been programming with PHP for many years and have used a lot of editors and so-called IDEs, I must admit that PHP IDEs have become much better now and they differ significantly from simple editors with syntax highlighting.

Even though I don't program with C++ much these days, I still love the book entitled 'C++ Programming Language'

There is a preview version only, but the release version will come soon, I think it looks very promising.

Although there is a built-in control for advertisement rotation in ASP.NET, it is capable of showing image ads only. However, in the real life you often have to deal with the ads that require some JavaScript code, for instance, you want to put there AdSense code or want to use Flash banners instead of images. Thus, if you want to rotate complex ads, you have to develop your own control.

Having read a great variety of forum and blog posts, I met a lot of misconceptions about ASP.NET that definitely made people to turn away from ASP.NET. I won't argue whether ASP.NET is better than PHP (or Ruby on Rails) or not, instead I'll try to bust those myths.

I want to proceed with telling how to deal with uploaded images with ASP.NET. I have already showed how to resize images. However, that resizing method isn't perfect. It doesn't produce images of high quality.

In the previous tutorial I showed how to handle image uploads, how to validate some things and finally how to resize images retaining their proportions. This time I'll show you how to prevent uploading of files which size exceeds the defined limit.
