You could just use something like ELMAH which will give you pretty decent error logging. It is pretty flexible in terms of how and what it logs for you. Also you can add it with NuGet with minimal effort.

Or take a look at NLog

Use mutex to lock your writing procedure. I suggest mutex, and not lock() because can catch all pools/threads that may throw an error.

On MSDN there are the details about mutex and examples:

http://msdn.microsoft.com/en-us/library/system.threading.mutex.aspx

a simple example

public void LogThis(string LogDetails) 
{
    var mut = new Mutex(true, "LogMutexName");

    try
    {   
        // Wait until it is safe to enter.
        mut.WaitOne();

        // here you open write close your file
    }
    finally
    {
        // Release the Mutex.
        mut.ReleaseMutex();
    }   
}
