Description Andrew Finnell 2011-08-14 08:27:21 UTC
The Windows 32-bit download from mono-project.com for 2.10.4 contains an invalid ._Microsoft.VisualBasic.dll metadata file.

Looking at it with a HEX editor it appears it was quarantined by a Mac OS X machine.

It contains the strings:

"Mac OS X"

As a result builds that directly/indirectly need this metadata file fail with:

     [exec] : error CS0009: Metadata file `C:\PROGRA~2\MONO-2~1.4\lib\mono\gac\Microsoft.VisualBasic\\._Microsoft.VisualBasic.dll' does not contain valid metadata

Looking at 2.10.3 this file seems to have the same problem
Looking at 2.10.1 this file does not exist in the install
Comment 2 Andrew Finnell 2011-08-14 08:35:48 UTC
Removing the files from the file system appear to solve the problem. It seems the compiler auto imports anything with ._ as the start of the file name. These files are still included in the default install of 2.10.3 and 2.10.4. Suggest a rebuild of 2.10.4 for Windows.

Moved to Class Libraries based on suggestion from #mono
Comment 4 Alex Corrado [MSFT] 2011-08-18 20:18:11 UTC
These quarantine files appear to be present for almost all, if not all, the files in the release, so I've renamed this bug to cover the general problem.

I am not sure what is causing these files to be created, but it sounds like we can just add a packaging step to delete them if they exist before the Windows installer is created.

This is fixed in mono 2.10.5.
