MonoDevelop iPhone simulator exits on load when running in debug, issue appears to be tied to one content file

When I run my iOS project in MonoDevelop through the simulator I get the following application output:

Mono.Debugger.Soft.VMDisconnectedException: Exception of type 'Mono.Debugger.Soft.VMDisconnectedException' was thrown. at Mono.Debugger.Soft.Connection.SendReceive (CommandSet command_set, Int32 command, Mono.Debugger.Soft.PacketWriter packet) [0x00000] in :0 at Mono.Debugger.Soft.Connection.Type_GetInfo (Int64 id) [0x00000] in :0 at Mono.Debugger.Soft.TypeMirror.GetInfo () [0x00000] in :0

Followed by the app exiting.

There's some .pngs which i copy over into the application. If I take one png and under its properties if I toggle between 'Copy Always' and 'Copy if Newer' in its 'copy to output directory' field then do a full rebuild the app runs fine. But after I stop running the simulator and try again it quits with the same issue and I have to again toggle the field and reibuild the app.

This is really strange to me, does anyone know how to fix this so I don't have to keep doing this obscure thing to get the app running?

This issue only happens when in debug mode.

edit: here's the actual application output:

I also found that if I make the game update at 30fps inste开发者_JAVA技巧ad of 60fps this issue happens far less frequently..

I had the same issue if I added the images into a "Resources" file, try renaming the pngs that you use. The way I made it work is to load all the images as "Content" in "Build Actions" and by specifying complete paths for every instance.

Once I fixed the issue with all my images being stored in a Resources file, my simulator worked again. If none of this works, I'd select the iOS simulator itself and try "Reset Content and Settings" and then debug your app once again.

This thread might prove helpful MonoTouch debugger never connects to app

Restaring OSX and clearing out the simulator seems to have done the trick. I'm still not sure what was causing it to begin with.
