Plugin for highlighting boxing/unboxing?

Question

C++ / C#

We are looking for a plugin for highlighting type packing / unpacking operations in the code.

Example:

interface ISomething {}
struct Something {}
static class Ext { public static void DoSomethingWithSomething(this ISomething sth){} }
//…
var mySomething = new Something();
mySomething. DoSomethingWithSomething ();

I would like to see the underline from the example in the code editor with a note that the type will be boxed.

I was looking for such a plugin both for the resharper and for the studio as a whole, but did not find it (

Answer 1

You can write your own, although code analysis is not an easy task. Alternatively, you can offer JetBrains to implement such a feature, perhaps they will do it in a few months, although how relevant this is for the bulk of developers is a question.

Answer 2

You can use ildasm to search for box / unbox operations with reference to lines of code.
Well, or see how you can access the IL code from the plugin and write.
