title: File name ... differs from already included file name ... only in casing
body: <p>I’m getting the following error in VSCode in my Angular 6 application:</p>
  
  <pre><code>ERROR in src/app/providers/dynamic-data/dynamic-data.service.ts(5,26): error TS1149: File name '/Users/gibranshah/repos/eva/EVA/src/app/model/endpoint.ts' differs from already included file name '/Users/gibranshah/repos/eva/EVA/src/app/model/Endpoint.ts' only in casing.
  </code></pre>
  
  <p>It’s telling me that this line in dynamic-data.service.ts:</p>
  
  <pre><code>import { Endpoint } from '../../model/endpoint';
  </code></pre>
  
  <p>…refers to a file whose name is Endpoint.ts. But there is no such file. Instead, I have endpoint.ts. endpoint.ts contains a class like this:</p>
  
  <pre><code>export class Endpoint {
  …
  }
  </code></pre>
  
  <p>endpoint.ts might have been named ‘Endpoint.ts’ at one point, put it’s not anymore.</p>
  
  <p>I tried to do a find for ‘Endpoint.ts’ but came up short:</p>
  
  <pre><code>M0168169000:gibranshah gibranshah$ find * -name "Endpoint.ts"
  M0168169000:gibranshah gibranshah$ 
  </code></pre>
  
  <p>Does VSCode cache files? Is it possible it’s using a cached version of Endpoint.ts? How do I fix this problem?</p>
