CS0133 will be raised if you are assigning to a constant. This fix will change const <type> to var.

This:

const string myStr = "abc".ToUpper();

Becomes, if it is a local variable:

var myStr = "abc".ToUpper();

Becomes, if it is in a field:

readonly string myStr = "abc".ToUpper();

Category: Compiler (same as CC0133, has to be added to SupportedCategories.cs)

@Poojith is working on it.
