Description
extern alias Contracts1;
extern alias Contracts2;
using alias1 = Contracts1::TestContractAssembly;
using alias2 = Contracts2::TestContractAssembly;
partial class Contract : alias1.IContract, alias2.IContract
{
int alias1.IContract.x
{
get
{
return 1;
}
}
int alias2.IContract.x
{
get
{
return 1;
}
}
}
Both IContract types are the same - they expose an int property "x". Roslyn incorrectly reports that IContract.x has already been implemented.
This works if you inline the using aliases.
I strongly suspect that the alias points to the merged namespace symbol, rather than to the namespace symbol contained in the assembly symbol referenced by the extern alias.
