F# style extension methods with `[<Extension>]` attribute applied generate C# incompatible method names

Although https://github.com/fsharp/fslang-suggestions/issues/835 is implemented the names of methods that are generated are incompatible with C# hence not shown in autocomplete.

As you can see method name `Exception.Reraise` is not compatible with C# because of dot.

**Expected behavior**

Either generate a compatible method name
Or produce a warning that asks to rename method using `CompiledName` attribute or suppress it

**Actual behavior**

Neither compatible name, nor warning.

**Known workarounds**

Apply `CompiledName` attribute
