I was checking ASP.NET official website and I saw a new post from Brada about changes in .NET Framework 3.5 SP1. It was nice and I have to thank him for his amazing post.

Lets take a look at .NET Framework 3.5 SP1 changes represented in the following link: what changed in .NET Framework 3.5 SP1

I just select some interesting parts:

# Assemblies    112
# Namespaces    919 to 935      (+16   +1.7%)
# Types    39 988 to 40 513      (+525   +1.3%)
# Methods    387 421 to 386 790      (-631   -0.2%)
# Fields    241 567 to 246 795      (+5 228   +2.2%)
# IL instructions    8 598 933 to 8 620 940      (+22 007   +0.3%)

Here is a 9000x1200 poster where methods where code was changed are located in blue (we degraded the quality to have a 2MB image file instead of 13MB):

And here is a list of coupling update for assemblies:

1. A blue cell means: {the X Assembly} is using {the Y assembly}.
2. Weight of a blue cell means: W members (methods and fields) of the {the X Assembly} are used by {the Y assembly}.
3. A green cell means: {the Y Assembly} is used by {the X assembly}.
4. Weight of a green cell means: W methods of the {the Y Assembly} are using {the X assembly}.
5. A black cell means: {the X Assembly} and {the Y assembly} are using each others.
6. A red tick on a cell means: the coupling has been changed.
7. A red tick with a plus on a cell means: the dependency has been created.
8. A red tick with a minus on a cell means: the dependency has been removed.
9. An assembly name underlined means that its code has been changed.
