Reading System libraries implementation

I was interested in how .NET's System.Boolean implemented it's TryParse method. I was wondering how you would read about the actual implementation.

I know I can use ILSpy (for C#) to perform Reflection on the dll but I can't find the dll because it's in metadata. Or that I don't know where to look for.

I can find it here: https://referencesource.microsoft.com/#mscorlib/system/boolean.cs but is there a way to view it locally on my machine without accessing the site?
