title: How can I exclude files from Visual Studio, but still deploy them upon publishing?
body: <p>We are experiencing bad slowdowns in Visual Studio 2019 that appears partly due to a large folder of content (~12,000 files) that we have in our wwwroot folder. This content rarely changes, but it ends up getting searched when we do "Find in files...", etc. which we don't need, and ends up slowing down normal operations such as adding/renaming classes.</p>
  
  <p>Is there any way to keep the content in source control, exclude it from Visual Studio, yet still have it get deployed when we publish?</p>
  
  <p>I haven't been able to figure out if this is possibly editing the csproj file using the settings such as DefaultItemExcludes, or various options on the ItemGroup element.</p>
