Question

My project and web services work fine in the simulator but crash when uploading to an iPhone. It had been working fine before I updated Monotouch from 1.1. Can I revert back to earlier versions of Monotouch? Here is the problem:

I have a monotouch app using web services. When I export the project to Xcode, I get a build error stating:
System.Web.Services.dll.mdb: No such file or directory

In the folder explorer that file is highlighted in red because there is nothing there.

Does anyone have a working System.Web.Services.dll for the latest version of monodevelop and monotouch?

Here is the stack trace on exit error in xCode:

Using your Web.Services.dll I think I got a shorter stack trace on error.

Answer 1

System.Web.Services.dll.mdb should be installed. Have you tried reinstalling monotouch?

I ve uploaded System.Web.Services.dll and System.Web.Services.dll.mdb for you to try: here. Use at your own risk! And you should report the problem and provide any relevant info so that this problem can be fixed for real.
