I have an object which has ConcurrentDictionary field.
I am getting the error below, when accessing data in Ignite Shared memory.
System.InvalidCastException: [A]System.Collections.Concurrent.ConcurrentDictionary'2[System.String,CampaignEngine.Model.LookupItem] cannot be cast to [B]System.Collections.Concurrent.ConcurrentDictionary'2[System.String,CampaignEngine.Model.LookupItem].

Why can't Ignite deserialize ConcurrentDictionary?
Thanks...
Looks like you have importing issue somewhere in your code, maybe due to Why is Visual Studio telling me I need to reference System.Private.CoreLib?
Check any of your source files for reference to System.Private.CoreLib and replace it to System.Collections.Concurrent.

Any assistance would be appreciated
I'm using the mach.int library in a specification (see also this question), and I'm trying to define a constant that is of type int32:
let constant_out1: int32 = 1 in
…
However, when analyzing this, why3 returns the message:
This term has type int, but is expected to have type int32
I noticed that Bounded_int (which Int32 instantiates with type int32) has the following in it:
val of_int (n:int) : t
requires { "expl:integer overflow" in_bounds n }
ensures { to_int result = n }
However, I do not seem to be able to use this to cast 1 to int32. For example, if I use:
let constant_out1: int32 = Int32.of_int(1) in
…
I get the message unbound symbol 'Int32.of_int'. I've tried many permutations of this, all without any success. Can anyone provided guidance for how to tell why3 that I want 1 to be of type int32?
Our crawler log is filled with the following Index Out of Bounds Exception. Has anyone seen this error? Or have any ideas on how to resolve?

I am trying to load a file.
I have:
wf :: STMutable a File
wf = File.new "worlds/seed_77.world"
data PickleSerialization = pure native com.github.lands.PickleSerialization where
native loadWorld com.github.lands.PickleSerialization.loadWorld :: MutableIO File -> IO World throws IOException, IncorrectFileException
If I try to do:
PickleSerialization.loadWorld wf
I get this error, which seems very confusing to me:
[ERROR: 4]: type error in expression wf
type is IOMutable File
used as MutableIO File
wf returns an action that produces a file. loadWorld takes a file, not an action. I think this should work: wf >>= loadWorld.
MutableIO File represents a mutable file whereas IOMutable is an action that returns a mutable file. IOMutable is defined as (taken from the source):
--- This is an abbreviation for #ST RealWorld (Mutable RealWorld d)#
type IOMutable d = IO (MutableIO d)
Similarly STMutable is defined as,
--- The type of 'ST' actions that return a mutable value of type _d_
--- This is an abbreviation for #ST s (Mutable s d)#
type STMutable s d = ST s (Mutable s d)
I'm reading C++/CLI. I see this stuff:
Object^ CreateInstanceFromTypename(String^ type, ...array<Object^>^ args)
{
if (!type)
throw gcnew ArgumentNullException("type");
Type^ t = Type::GetType(type);
if (!t)
throw gcnew ArgumentException("Invalid type name");
Object^ obj = Activator::CreateInstance(t, args);
return obj;
}
When calling it:
Object^ o = CreateInstanceFromTypename(
"System.Uri, System, Version=2.0.0.0, "
"Culture=neutral, PublicKeyToken=b77a5c561934e089",
"http://www.heege.net"
);
What is ...array^ args? If I remove ... ,there's a complied-error:
error C2665: 'CreateInstanceFromTypeName' : none of the 2 overloads could convert all the argument types
1> .\myFourthCPlus.cpp(12): could be 'System::Object ^CreateInstanceFromTypeName(System::String ^,cli::array<Type> ^)'
1> with
1> [
1> Type=System::Object ^
1> ]
1> while trying to match the argument list '(const char [86], const char [21])'
Like C++, C++/CLI has a mechanism for a variable amount of arguments. That is what the ... in front of the ...array<Object^>^ parameter means.
For type safety the C++/CLI designers added managed syntax to declare the type of the variable array.
Since it's just passing that parameter to the Activator::CreateInstance() function, I would look at what variable parameters the Activator function is looking for.
