Description

If an assembly targetting .NET 3.5 has custom attributes with named parameters for a value type defined by the framework, retrieving the assembly's attributes data using CustomAttributeData.GetCustomAttributes(Assembly target) throws an exception with message {"Binary format of the specified custom attribute was invalid."} with the following stack trace:

   at System.Reflection.CustomAttributeEncodedArgument.ParseAttributeArguments(IntPtr pCa, Int32 cCa, CustomAttributeCtorParameter[]& CustomAttributeCtorParameters, CustomAttributeNamedParameter[]& CustomAttributeTypedArgument, IntPtr assembly)
   at System.Reflection.CustomAttributeEncodedArgument.ParseAttributeArguments(ConstArray attributeBlob, CustomAttributeCtorParameter[]& customAttributeCtorParameters, CustomAttributeNamedParameter[]& customAttributeNamedParameters, Module customAttributeModule)
   at System.Reflection.CustomAttributeData..ctor(Module scope, CustomAttributeRecord caRecord)
   at System.Reflection.CustomAttributeData.GetCustomAttributes(Module module, Int32 tkTarget)
   at System.Reflection.CustomAttributeData.GetCustomAttributes(Assembly target)


Retrieving the actual attributes succeeds. Unfortunately, the ResourceManager class loads attribute data, not attributes, causing this failure.

There is no information about how it has been fixed(if it is!), and how we should take care of it. is there any specific patch for this?
