Customer reported an issue when building from a mac where the solution is stored on a shared network folder, and there is a pre-build event to swap out some files. Attached to this report is a sample project to illustrate the issue.
Steps to reproduce:
1. Create a shared folder on a windows machine and place the sample application in that folder.
2. On a Mac, browse to the shared folder and open the solution in Xamarin Studio.
3. Build the solution.
It will fail (about) every other build attempt with the exception information below.
Build successfully every time.

Failed Build Output Log
Stack trace points to Xamarin Studio tooling (addin).
The problem looks like reading from a Windows share is flaky - i.e. the exception happens because we try to read an integer from a file stream and the stream reads 0 bytes when there are, in fact, more bytes to be read.
Might be a bug in the Mono runtime or just a bug in OSX's support for reading files on a Windows share.
Can somebody create a test case for this ?
Hey Zoltan, I attached a project that can be used, is there anything else I can help provide?
We need a test case that shows what the VSfM tooling is trying to do and mono supposedly failing at.
A solution that requires using the whole VSfM is not usable by us.
Wow impressive response time for the enterprise level support ...
Close this for me, we no longer build over samba since no one could be arsed to follow this up in under 3 years..
closing per last comment.
