Description

Brief description: Today, you can re-order method parameters with a nice dialog like so: image

But there is no method for re-ordering type parameters. All

Additional Information: If I have code like this:

public class Foo<T1, T3, T4, T2> { }

and want to refactor it to:

public class Foo<T1, T2, T3, T4> { }

Today, I have to touch every single place they are used by hand. This basically makes the refactoring impossible.

Contributor guide

Research direction
Examine the existing 'Reorder Parameters' refactoring in the Roslyn codebase and extend it to handle type parameters similarly.
