.NET 3.5 SP1 Beta: Changes Overview

Patrick Smacchia — Tue, 13 May 2008 17:01:00 GMT

Scott Hanselman just published a blog post where he used NDepend to see changes in the code of .NET 3.5 SP1 beta (that has just been released). Let’s expose the exhaustive list of differences:

Summary:

# IL instructions: 8 598 933 to 8 589 008 (-9 925 -0.1%)

# Assemblies: 112

# Namespaces: 919 to 929 (+10 +1.1%)

# Types: 39 988 to 40 402 (+414 +1%)

# Methods: 387 421 to 385 253 (-2 168 -0.6%)

# Fields: 241 567 to 246 320 (+4 753 +2%)

636 new public methods:

SELECT METHODS WHERE IsPublic AND WasAdded

57 new public types:

SELECT TYPES WHERE IsPublic AND WasAdded

3.137 public methods removed (this number is biased by the fact that a public methods can be declared in an internal types):

SELECT METHODS WHERE IsPublic AND WasRemoved

8 public types removed:

SELECT TYPES WHERE IsPublic AND WasRemoved

5.623 methods where code was changed:

SELECT METHODS WHERE CodeWasChanged

2.024 types where code was changed:

SELECT TYPES WHERE CodeWasChanged

The list of assemblies we consider is made of 112 assemblies.

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:

A blue cell means: {the X Assembly} is using {the Y assembly}.
Weight of a blue cell means: W types of the {the X Assembly} are used by {the Y assembly}.
A green cell means: {the Y Assembly} is used by {the X assembly}.
Weight of a green cell means: W types of the {the Y Assembly} are using {the X assembly}.
A black cell means: {the X Assembly} and {the Y assembly} are using each others.
A red tick on a cell means: the coupling has been changed.
A red tick with a plus on a cell means: the dependency has been created.
A red tick with a minus on a cell means: the dependency has been removed.
An assembly name underlined means that its code has been changed.
