Is is possible to sign a binary via .NET code? (no signtool.exe)

I've the following requirement, sign a binary with a certificate, but without signtool.exe; the idea would be to do it via code.

Do you know if it's possible?

You will need to use the SignerSign or SignerSignEx functions that are exported from mssign32.dll.

To use these, you'll need to define managed versions of the SIGNER_SUBJECT_INFO, SIGNER_FILE_INFO, SIGNER_CERT, SIGNER_SIGNATURE_INFO, etc. structs, then correctly specify the P/Invoke signature for the native method.

Halfway through this blog post, there is a C++ example of calling SignerSignEx; Mark has ported it to C# in this StackOverflow answer.
