FileStream/StreamWriter in .NET Core 1.1 have no Close() method

I'm using .net core 1.1, previously when I was with .net framework, I usually call Close() on FileStream or any Stream after I finished the stream operations, but the FileStream class in .net core 1.1 doesn't have Close method, I found Dispose() but don't know if it's the equivalent. Anyone care to let me know the right way to correctly close with the new FileStream/StreamWriter class in .net core?

Running into this issue, trying to keep legacy code intact, another option would be to write an extension method.

public static class FileStreamExtension
{
    public static void Close(this FileStream reader)
    {
        reader.Dispose();
    }
}

Use using or build your own Dispose Pattern.

using (StreamWriter sw = new StreamWriter(path)
{

}

Implementing IDisposable means that you can use a using statement, which will implicitly call the Dispose() method, thus closing the stream.

Use 

using (StreamWriter sw = new StreamWriter(path))
{
    // your logic here
} // here Dispose() is called implicitly and the stream is closed
