hi julie, yes. the “Unknown type: wisej.web.ext.signature” appears also in your test project. Maybe some registry problem in my machine?
Also sending another project. (in this case in vb.net which has the same issue)
I tested with Wisej 3.5.6 as well as with the newest version of Wisej (3.5.8) and the Signature extension is working fine for me. See attached test case.
Some troubleshooting steps for you to follow:
