creating XSD schema files for GAC dll

How can I use XSD.exe to create an XML schema for the Mi开发者_运维知识库crosoft.AnalysisServices.Database object?

You can still access a gacced dll via the cmdline (in %windir%\assembly\GAC_MSIL):

C:\WINNT\assembly\GAC_MSIL>dir
 Volume in drive C is Omni3
 Volume Serial Number is 5CDE-38BA

 Directory of C:\WINNT\assembly\GAC_MSIL
