Right, params attributes aren't correctly supported. To be honest I didn't even know that they were permitted in .NET at all. Thanks for taking the time to report this.
I've recorded this as bug 1105 in the internal bug database at Microsoft. We plan to make entries in that database available externally at some point but haven't done that yet.
Thanks
Don
P.S. "tspec_of_typ" is an internal error meaning "we hit an array where we didn't expect one".

Hello,
I have been attempting to use MBUnit to run some row tests.
Unfortunately adding a Row attribute breaks to compilation and all there is to go by is “error: tspec_of_typ”
The Row attribute has a params array of objects signature.
public RowAttribute(params object[] row);
and I attempted to pass the attribute to a test but it does not compile.
[<Row([|(2 :> obj)|])>]
member this.Test (value:int) =
I replicated the issue using my own attribute.<BR style="mso-special-character: line-break"><BR style="mso-special-character: line-break">
[AttributeUsage(AttributeTargets.Method, AllowMultiple = true, Inherited = true)]
public class MBunitTestAttribute : Attribute
{
public object[] Row;
public MBunitTestAttribute(params object[] row)
{
Row = row;
}
}
using
type
Tests = class
[<MBunitTest([|(2 :> obj)|])>]
member this.Test (value:int) = ()
end
This also occurs if the params keyword is removed.
This seems to be an attribute specific thing as new () = { x = MBunitTestAttribute([|(2 :> obj)|]) } creating the attribute as a normal object works ok.<BR style="mso-special-character: line-break"><BR style="mso-special-character: line-break">
Any Ideas?
Also just passing and array the most approbriate way to calling a params method?
Thanks
Bart
