[vw 7.7.1] DotNETConnect UHE

Does anyone know what it means when the DotNETConnect Code Generator throws the exception:

‘System.ArgumentException: Culture name ''neutral'' is not supported.’

The entire string is:

'System.ArgumentException: Culture name ''neutral'' is not supported.

Parameter name: name

at System.Globalization.CultureTableRecord..ctor(String cultureName, Boolean useUserOverride)

at System.Globalization.CultureTableRecord.GetCultureTableRecord(String name, Boolean useUserOverride)

at System.Globalization.CultureInfo..ctor(String name, Boolean useUserOverride)

at System.Globalization.CultureInfo..ctor(String name)

at System.Reflection.AssemblyName.nGetFileInformation(String s)

at System.Reflection.AssemblyName.GetAssemblyName(String assemblyFile)

at Heeg.ReflectionProxy.Static_System_Reflection_AssemblyName_GetAssemblyName(ReflectionProxy* , return_type* vwReturnValue, Char* assemblyFile)'

Re: [vw 7.7.1] DotNETConnect UHE

Hi Charles,

according to http://msdn.microsoft.com/de-de/library/system.reflection.assemblyname.getassemblyname.aspx,
an ArgumentException is raised if assemblyFile is invalid, such as an assembly with an invalid culture.
However, the majority of the assemblies I have seen and used have Culture ''neutral'', this alone does not
trigger the error. E.g. the mscorlib, which is used by the Code Generator, has Culture ''neutral''.

Find attached a version of GACReader>>readAssemblies that will catch this error.
It is untested, as I have never seen this exception.

Regards,

Ralf Propach
