.net - Consuming SSL SOAP Service, could not establish secure channel for SSL/TLS -


i'm working on windows mobile 6.5 pro application, using .net compact edition 3.5.

i'm able contact standard web service (not using ssl), https won't go through. i've attempted add web reference ; 1 pointing https version. assuming generate proper code ssl, nothing.

every time attempt communicate service via code following:

an existing connection forcibly closed remote host. not establish secure channel ssl/tls.

i tested same code on .net 4.5 console app , able reach https web service , xml response without issues.

it appears generated web refence on vs2008 https missing something?

there's not code show here besides auto-generated code vs2008 produces when add new web reference.

update 1: i've been following post appears same issue i'm encountering sadly don't think resolved. how can establish secure channel ssl/tls handheld device?

update 2: after more research, windows mobile 6.5 pro appears support tls v1.0 while soap service attempting communicate v1.2 (latest).

a bit on tls , ssl: here.

ws 2003 had ssl 2.0/3.0 , tls 1.0 enabled default. default installation did not support aes ciphers – support added through hotfix.

ws 2008 had ssl 2.0/3.0 , tls 1.0 enabled default, improved cryptographic support new aes cipher suites.

ws 2008 r2 introduced tls 1.1 , tls 1.2, disabled default.

ws 2012 takes step further tls 1.2 enabled default.
