[Mono-list] Debugging binding Obj-C?
I'm having problems binding a precompiled third party framework. I keep getting a dyld error about being unable to find the library but it only shows the error after I've done the binding, added the library to a project, compiled the project and deployed it to the device, watched it crash, and looked at the error log on the device. Is there a way to test the binding as soon as the dll is made? How would I make sure the binary blob is included and adjust the path reference internally in the dll to make sure it's correct?

[Mono-list] Native number types but not general number type?
With the addition of native number types I have returned to an old line of thought about why C# doesn't have a general Number type with other number types in some sort of hierarchy under it. Obviously there are times when using a very specific number type is important for performance or compatibility but usually I don't really care. I probably don't care if the number is represented as 32 bits or 64 bits, if it's signed or not, if it is whole numbers or fractional, etc. So long as the behavior is correct when casting to a more specific type I'd rather it just work with the least amount of effort. Likewise I'd like to more easily use lossless numbers of unlimited size, including fractional values, when needed and easy manipulation of numbers into different representations (such as byte order, different ways of storing the sign, etc). Something similar to changing text encodings. A general number type seems it'd ease portability even more than native types. It was mentioned that Mono may push for these native types to made standard. Is there a technical reason a general number type couldn't be, or shouldn't be, introduced? Not asking anyone to actually doing it so much as trying to understand the problem.

Re: [Mono-dev] making mono builds reproducible (xamarin bz #26842)
I'd always store time in epochs. Seconds since 1/1/1970 GMT. The use of textual date strings instead of a epochs is one of the worst things I've seen from the C# way of doing things. I had often wondered why so many programs could have so much trouble with handling dates and times correctly..

[Mono-list] Specific thread for event?
I had the general idea of making an event that would invoke every handler in its list on the thread it was registered from. So I added accessors that'd store the thread and set things up so when I invoke the handlers it'd use those threads .. only there seems to be no way to run code on a specific thread in C# (possibly if I did something unsafe with internal threading?) as far as I can see. I messed around with the ExecutionContext and various other things but none seems to let you interrupt a running thread, do something, and resume. The best I have been able to manage is having the main UI thread get special treatment in iOS. That's actually what I want but I'd like a more universal solution as it's likely I'll have other components that are picky about what thread they're on. Seems like having events raised on the correct thread automatically would be a good behavior and avoid a lot of boilerplate code. Obviously something has been done with iOS to make it possible to access the main thread. Am I missing something or is this pretty much a deadend?

[Mono-list] Marshaling a struct with network byte order?
Is there any common way to correctly marshal a struct such that the resulting bytes are in network byte order? I have a file format that requires this order for compatibility. Currently I'm storing each chunk as a struct and am using Marshal to convert it to/from bytes. Seems to work fine other than being little endian. Is there something like a MarshalAs attribute for controlling byte order? Couldn't find a general .NET/C# way other than doing it with Array.Reverse() each time.

[Mono-list] MemoryMappedFile not supported?
I'm experimenting with writing a local service that I need to be reasonably fast. I'd like it to work on Windows, Mac OS, and Linux at least. I've never written a service in C# but the first thing I tried for IPC was using memory mapped files. Immediately I got a complaint that what I was doing wasn't supported under Mono because it didn't jive with Unix.. so I switched to creating from a file (as the previous error message told me to do) but it seems if the file exists it dies with an error about the file already existing and if the file doesn't already exist it dies with an error that the file doesn't exist. Is this just plain not the right way to make a fast local service in C#? I'd be ok with using pipes or IPC sockets if it is a better idea but in Googling it seemed that C# had made these rely on networking for some reason.
