Hello,
I just tried to sign my assemblies with my newly generated
certificate, but I get just error message when compiling the assembly.
I was following this article: http://www.codeproject.com/useritems/signcode.asp
, generated my certificate with blank password and afterwards used the
*.pfx file for signing in the VS project settings.

The error message:
genasm.exe(1) : error There was an error initializing .  Invalid
public key of assembly (HRESULT: 0x8013141E)

I also tried to generate new pfx certificate file directly from VS
project options dialog, but the compiler exception persists. Is there
any method how to get the signing working?

I used a snk file succesfully before, but I need to create the
provisioning file for WM devices and didn't found any method how to
get public part of the certificate to be able to get the SHA and
base64 values for building _setup.xml provisioning file. Is there any
method how to install certificate from a snk file on the device?
