[Mono-list] Extension method not found

[Dr_Asik]

Hello,

I am having a weird problem with Mono. I have a solution made of 2 projects
A and B, targeting Mono/.NET 3.5. In project A, I have a class called
BinaryExtensions which define a bunch of extensions methods for
System.IO.BinaryReader and BinaryWriter. Both projects A and B use some of
these extensions methods; project B references project A for that reason.
For some reason, project B fails to find one of the extensions methods when
compiling.

The whole thing works perfectly fine under VS2010. Using Monodevelop 2.4
under Ubuntu 10.04 to compile my code, however, I get CS1061 (Type
'System.IO.BinayReader' does not contain a definition for funcX and no
extension method could be found). The thing is, the method in question is
used successfully by project A. Project B also successfully uses other
extensions methods from BinaryExtensions. But it fails to find one
particular function. Here is the code for that function:

        public static string ReadNullTerminatedASCIIString(this BinaryReader
binaryReader, int count) {
            var rawBytes = binaryReader.ReadBytes(count);
            rawBytes = rawBytes.TakeWhile(b => b != 0x00).ToArray();
            var chars = Encoding.ASCII.GetChars(rawBytes);
            return new string(chars);
        }

Again, this function is used by projectA and projectA compiles fine. Also,
other extension methods of that class are used by projectB and generate no
errors.

Also, when I use the assembly browser to check projectA, all extensions
methods decompile fine except for the method in question. I get:
