PostSharp.Sdk.CodeModel.AssemblyLoadException: Cannot find assembly 'mscorlib, version=2.0.5.0

After a recent updated to Windows 8.1, my VS 2013 no longer compiles my solution.

Any ideas what could be causing this behavior? A windows 7 machine with same VS2013 and code, works just fine.

UPDATE

As soon as I added this code back, the compilation error re-appeared:

TypeMap[] allTypeMaps = Mapper.GetAllTypeMaps();
foreach (TypeMap typeMap in allTypeMaps)
{
    foreach (PropertyMap propertyMap in typeMap.GetPropertyMaps())
    {
        if ((propertyMap.SourceMember as PropertyInfo).PropertyType.Name !=
            propertyMap.DestinationPropertyType.Name)
        {
            _log.WarnFormat("Types not matching {0}.{1} <> {2}.{3}", typeMap.SourceType.Name,
            propertyMap.SourceMember.Name, typeMap.DestinationType.Name,
            propertyMap.DestinationProperty.Name);
        }
    }
}

_log is ILog from Log4Net, but it is used in other places without any issues.

Solution

  • I had resolved this issue (for a different assembly) on my .Net 4.5.1 project by adding the following to the 

    <DontImportPostSharp>True</DontImportPostSharp>
<PostSharpTargetFrameworkVersion>4.0</PostSharpTargetFrameworkVersion>
