Hi all,
I was playing around with Assembly.Load and noticed a couple of diffences in behaviour.
First the Assembly.FullName property emits different strings on Mono and MS .NET. Mono emits the full four-part name (name, version, culture, public key). Even if these values are not specified, default values are emitted. On the MS .NET platform only the parts specified are emitted.
I've yet to look what the spec says about this; perhaps both are permitted.
The two sessions attached to this mail show that using Assembly.Load fails on Mono but works on MS .NET. I'm not sure if the Assembly.FullName property has anything to with it.
BTW. Here some version info... I have not yet been able to try Mono Beta 2.
