FileAccess parameter in File.Open() is ignored when the FileMode is Create or CreateNew. #713
Description
Describe the bug
FileAccess parameter in File.Open() is ignored when the FileMode is Create or CreateNew. Bug can be observed by checking the CanRead property of the returned Stream with FileAccess.ReadWrite.
To Reproduce
Below code snippet compares actual behavior to the mock:
var tempFile = Path.GetTempFileName();
using var fs = File.Open(tempFile, FileMode.Create);
Console.WriteLine(fs.CanRead);
var mock = new MockFileSystem();
var mockFile = mock.Path.GetTempFileName();
using var mockFs = mock.File.Open(mockFile, FileMode.Create);
Console.WriteLine(mockFs.CanRead);Output:
True
False
Expected behavior
Mock behavior should match the .NET type.
