Original Pull Request: https://github.com/adamhathcock/sharpcompress/pull/895

State: closed
Merged: Yes

When running all tests concurrently, it could happens that multiple tests accessed the same test file at the same time.

This should not be an issue when just reading the files, however the usage of File.Open without a FileShare parameter made the access exclusive and caused each subsequent call to fail. This was especially noticable in the Zip_Uncompressed_64bit test due to the long time it takes.
