I'm developing some software using visual studio where I target v4.5 of the CLR, this software is also being run on Mono v220.127.116.11
All is well until I try to use extension methods, at which point I get the following exception System.TypeLoadException: Could not load type 'System.Runtime.CompilerServices.ExtensionAttribute' from assembly ......
Now if target v4.0 of the CLR with visual studio and run on Mono all is well, I have noticed that the System.Runtime.CompilerServices.ExtensionAttribute class has moved from the System.Core.dll in v4.0 of the CLR to the mscorlib.dll in v4.5
When I run he pedump tool with --verify metadata,code on one of my assemblies I get
Missing method .ctor in assembly myassembly.dll, type System.Runtime.CompilerServices.ExtensionAttribute Error: Invalid CustomAttribute content row 1 Value field 0x00000109 Error: CustomAttribute: Invalid constructor Error count: 2
Has anyone had similar issues ? Any resolutions ?
thanks in advance
I had the same issue today. Resolved by upgrading the (Debian Wheezy) server to the latest Mono; the staging servers had been Ubuntu Trusty and they did not exhibit this problem.
So this is fixed in Mono 3.2.8+ (which is Ubuntu Trusty's version).
