Test program which illustrates the compile error.
User-Agent: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.6; en-US;
rv:1.9.2.10) Gecko/20100914 Firefox/3.6.10
Using the attached code a CS1061 is generated when running gmcs or dmcs.
I'm using the 2.8.1 branch from Git.
gmcs Main.cs
Main.cs(19,27): error CS1061: Type `W' does not contain a definition for
`Start' and no extension method `Start' of type `W' could be found (are you
missing a using directive or an assembly reference?)
It seems that the MemberCache.FindMembers is only looking at the BaseType,
instead of also inspecting the TypeArguments to determine if a member exists.
Reproducible: Always
Steps to Reproduce:
1. Compile the attached code.
Actual Results:
Compile Error
Expected Results:
Should compile. This code compiles on Windows using .NET 3.5 and compiled with
Mono 2.6
