I have a custom-built binary that recently starting throwing fits on the
Compact Framework. The same binary built the same way for the desktop runs
fine, but when I built it for CF it fails to load. If I remove the strong
name from the CF binary, it loads just fine.

This binary is non-standard in that it wasn't entirely created by Visual
Studio. The .NET assembly manifest and IL code is not in the same place
inside the DLL as would normally appear in a pure CSC-created assembly, but
all the PE headers, COR20 headers and metadata are correct for the binary.

After building the binary, SN -v verifies the signature, and PEVerify /MD
/IL indicates the assembly is valid. If built for the desktop, the desktop
DLL works perfectly.

The capper is that previous versions of the CF binary ran just fine, built
using the same methods and strong named. It's only been recently when more
code was added that the binary suddenly stopped loading on the CF. The
binary is approximately 400kb

Here's are two netcf_loader logs, the first with the strong name (fails to
load) and the second log without the strong name (successfully loaded)

Well I'm sure nobody else will encounter this error since I appear to be the
only one on the planet making mixed-mode DLL's on the Compact Framework ...
but in case anyone's interested in the solution for academic purposes:

It appears that Strong Name validation on the Compact Framework may be
slightly flawed. In the case of my particular binary, the .data segment of
the PE file looked like this:

SECTION HEADER #3
.data name
340 virtual size
4C000 virtual address (1004C000 to 1004C33F)
200 size of raw data
4A400 file pointer to raw data (0004A400 to 0004A5FF)
0 file pointer to relocation table
0 file pointer to line numbers
0 number of relocations
0 number of line numbers
C0000040 flags
Initialized Data
Read Write

Notice that the SizeofRawData field is less than the VirtualSize. This can
happen, and its not unusual in a native EXE/DLL. However for managed
assemblies, there never occurs an instance where the VirtualSize of any
segment is larger than the RawData size -- just a side-effect of the way
managed assemblies are built.

When a strong name is assigned to the DLL, all the sections of the PE file
are iterated and the strong name hash is computed based on the VirtualSize
of each section in the PE file. Now on the desktop, strong name validation
works using the same principle. This is why I never had any issues on the
Desktop.

However, on the CompactFramework, it appears that the strong name validation
routine is probably using a formula somewhat akin to min(VirtualSize,
RawDataSize) to determine the length of the section for hashing it. The
result is that the strong name computation function on the Compact Framework
is not computing the entire section and is throwing off the final hash
value.

To prove the theory, I added this code to the native source to artificially
increase the .data segment to force the RawData size to increase by the
specified FileAlignment:

DWORD _ph[] = {0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15};

Re-compiling this code triggers expansion of the .data segment's RawData
size such that it is now larger than the VirtualSize.

When I re-deployed the modified binary in the Pocket PC 2003 SE emulator, it
worked flawlessly.

I noticed that the non-strong-named assembly looked in the GAC first and
then the program files directory. It does not specifically mention
looking in the GAC for your strong-named assembly, but I bet that it
wants to find the strong-named file there. Try adding the strong-named
assembly to the GAC and see if the error still occurs.

I have a custom-built binary that recently starting throwing fits on the
Compact Framework. The same binary built the same way for the desktop runs
fine, but when I built it for CF it fails to load. If I remove the strong
name from the CF binary, it loads just fine.

This binary is non-standard in that it wasn't entirely created by Visual
Studio. The .NET assembly manifest and IL code is not in the same place
inside the DLL as would normally appear in a pure CSC-created assembly, but
all the PE headers, COR20 headers and metadata are correct for the binary.

After building the binary, SN -v verifies the signature, and PEVerify /MD
/IL indicates the assembly is valid. If built for the desktop, the desktop
DLL works perfectly.

The capper is that previous versions of the CF binary ran just fine, built
using the same methods and strong named. It's only been recently when more
code was added that the binary suddenly stopped loading on the CF. The
binary is approximately 400kb

Here's are two netcf_loader logs, the first with the strong name (fails to
load) and the second log without the strong name (successfully loaded)

Thanks, but I was able to come up with a workaround (posted as a reply to my
own post). The problem was strong name validation was failing due to an
inconsistency in the way the strong name was computed on the desktop and
verified on the Compact Framework. I doubt seriously the assembly could've
made it into the GAC to begin with since GAC registration requires the
assembly be loaded and its hash verified -- which was exactly the step that
was failing.
