Summary: type inference bug prevents compilation of nhibernate
Product: Mono: Compilers
Version: SVN
Platform: x86-64
OS/Version: Linux
Status: NEW
Severity: Critical
Priority: P5 - None
Component: C#
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
QAContact: [EMAIL PROTECTED]
Found By: ---
The following code does not compile -- the compiler tries to use type inference
on generic version of method B.Foo<T> () from method B.Goo () instead of using
non-generic method B.Foo (). The problem seems to happen only when the methods
are overriden.
using System.Collections;
using System.Collections.Generic;
class A
{
public virtual IList Foo (string s)
{
return null;
}
public virtual IList<T> Foo<T> (string s)
{
return null;
}
}
class B : A
{
public IList Goo (string s)
{
return Foo (s);
}
public override IList Foo (string s)
{
return null;
}
public override IList<T> Foo<T> (string s)
{
return null;
}
}
class C
{
public static int Main ()
{
new B ().Goo ("q");
return 0;
}
}
Error message:
foo.cs(21,5): error CS0266: Cannot implicitly convert type
`System.Collections.Generic.IList<T>' to `System.Collections.IList'. An
explicit conversion exists (are you missing a cast?)
Compilation failed: 1 error(s), 0 warnings
Mono is compiled from SVN rev.90461. I have not seen any related changes in
compiler since that revision.
I think this is critical as many other projects may be also affected.
