“Why is my .net exe so huge” analyzer tool?

问题:

Is there a tool that can explain the size of a .NET assembly (executable or DLL file)?

In the olden days, there was an IDE extension that would detail the space used by a project.

It should show the large code files:

And data resources:

Is there such a thing for the .NET world?

I really thought that moving to .NET, and no longer having to build the entire VCL into the executable, that executable sizes would shrink.

The standard SDK took ILDASM (IL Disassembler), had the "Statistics" option in the View menu, which broke it down like this:

 File size            : 3072
 PE header size       : 512 (456 used)    (16.67%)
 PE additional info   : 167               ( 5.44%)
 Num.of PE sections   : 2
 CLR header size     : 72                 ( 2.34%)
 CLR meta-data size  : 1572               (51.17%)
 CLR additional info : 0                  ( 0.00%)
 CLR method headers  : 15                 ( 0.49%)
 Managed code         : 77                ( 2.51%)
 Data                 : 512               (16.67%)
 Unaccounted          : 145               ( 4.72%)

 Num.of PE sections   : 2
   .text    - 2048
   .reloc   - 512

 CLR meta-data size  : 1572
   Module        -    1 (10 bytes)
   TypeDef       -    4 (56 bytes)      0 interfaces, 0 explicit layout
   TypeRef       -   15 (90 bytes)
   MethodDef     -    4 (56 bytes)      0 abstract, 0 native, 4 bodies
   FieldDef      -    2 (12 bytes)      0 constant
   MemberRef     -   15 (90 bytes)
   ParamDef      -    4 (24 bytes)
   CustomAttribute-   13 (78 bytes)
   StandAloneSig -    1 (2 bytes)
   Assembly      -    1 (22 bytes)
   AssemblyRef   -    1 (20 bytes)
   Strings       -   571 bytes
   Blobs         -   336 bytes
   UserStrings   -     8 bytes
   Guids         -    16 bytes
   Uncategorized -   181 bytes

 CLR method headers : 15
   Num.of method bodies  - 4
   Num.of fat headers    - 1
   Num.of tiny headers   - 3

 Managed code : 77
   Ave method size - 19

This should provide a good starting point.
