I noticed this bug when I created a new project in VS2019. It doesn't appear to happen in my old project.

• This is not a crash
• This changed between versions vs2017 and vs2019
• I tried updating vs2019 - the problem was not fixed.
• I was unable to test this on prior versions because I don't think I can download older versions of vs2019.

💻 The problem:

Trying to rename any class, interface or variable that is exported from one file and used in any other file works (in that you can type out the new name) but fails to apply. An error shows at the top of the window and the edited property reverts to it's original name with an extra newline inserted where the cursor was.

e.g.

export class RenderOrganiser {
    //... other code
}

When I try to use rename to edit it to be:

export class RenderOrganiserABAB {
    //... other code
}

It instead becomes:

export class RenderOrganiser
 {
    //... other code
}

And the following error occurs in the log:
