Description Joe 2012-08-16 14:17:41 UTC
Compiling such as:
mcs /sdk:4 /r:...System.dll SomeFile.cs

fails with "An assembly with the same identity `System, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089' has already been imported"

Removing the /sdk:4 allows it to continue.

Mono 2.11.3 and 2.10.8.

I am not sure what you are doing but you are importing duplicate System reference from different locations hence the compiler error.

This is coming from http://raptordb.codeplex.com/. With .NET on Windows, it is working. I'll try to get the full command line causing this.
