allowed clock skew is '00:05:00'
I had the same issue and followed all recommendations. But my fault was that I changed only server configuration, whereas I had to change client configuration too.
This is my config without maxClockSkew
And updated with clock skew

c# Reading file occurs The process cannot access the file 'Path' because it is being used by another process.
using(var fs = new System.IO.FileStream(@"Path", System.IO.FileMode.Open, System.IO.FileAccess.Read, System.IO.FileShare.ReadWrite))
using (var sr = new System.IO.StreamReader(fs))
{
string line;
while ((line = sr.ReadLine()) != null)
{
Console.WriteLine(line);
}
}
If you just need whole text not lines, then use this code for better performance
using (var fs = new System.IO.FileStream(res.path, System.IO.FileMode.Open, System.IO.FileAccess.Read, System.IO.FileShare.ReadWrite))
using (var sr = new System.IO.StreamReader(fs))
{
return sr.ReadToEnd();
}
