ClickOnce Permissions Rqd for XMLSerializer

[Rich S.]

Hello,

I have a C# .NET 2.0 program which accesses the Amazon.com E-Commerce web
service. I am debugging it as a ClickOnce Partial Trust application.

My question is, What permissions are required for the
XMLSerializer.Serialize method? This is where the application constantly
bombs with an InvalidOperationException.

The app runs without any errors when debugged as "Full Trust." However,
when debugged as Partial Trust, even with ALL permissions granted, it fails
on that method call.

I created the web reference using the Wizard. The message of the
InvalidOperationException is "There was an error generating the XML document"
and the InnerException is a SecurityException "Request Failed."

Thanks for any help that can be offered!

Hi,

You need to include WebPermission to call the web service.

Hi Sayed,

Thanks for the reply. Unfortunately, I have already tried including
WebPermission. As I said in the original post, I "include" every permission
listed in the box, and it still fails!

Sorry...I didn't see the portion of your message that said you added
all permissions. Anyway, I can't replicate your problem but I believe
the XmlSerializer's serialize method creates a temp file when doing the
serialization. If you included FileIOPermission then you should have
unrestricted access to the file system so that should be a problem
either. Just a thought. Other than that, I can't guess what the problem
might be....
