Copy to Output - Copy Folder to Output Follow

I have filed something close to your request to our tracker. Please feel free to upvote/comment
https://youtrack.jetbrains.com/issue/RIDER-9366

I am also curious, what problems do you have with wildcards?

Here are couple of examples:
<Content Include="fonts\*" />

for everything in the fonts folder

<Content Include="fonts\**\*" />

for everything in the fonts folder and its subfolders.

Apologies for the delayed response.  I missed this notification in my email.

I can edit the project and do something like this:

<ItemGroup>
  <Content Include="assets\ui\**\*">
    <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
  </Content>
</ItemGroup>

That seems to copy all my images to the bin folder on build (they are loaded at runtime), but I don't see a way to do this through the UI. 

Maybe a better request I could have made would be for a folder to have a properties setting that allows you to specify that its content should be copied to the output folder?

Or perhaps I'm missing something here?

Thanks.

Is the same approach supposed to work for Unit tests (NUnit)? I have folder with a subfolder that contains some files in the test project. I have marked one of the files to be always copied to the output folder via Rider UI. Then, I used 

System.IO.Directory.GetDirectories(".", "*")

and

System.IO.Directory.GetFiles(".")

inside a simple test to verify whether files/folder are indeed copied but I couldn't find any.

UPD: Apologies, I was wrong. File was actually being copied, just not in the path returned by 

System.IO.Directory.GetCurrentDirectory()

I was able to get the right path using 

Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location)

from inside the unit test, however I'm not sure if there is a better way to get the same path.

Having said the above, I was still only able to copy individual files, not the whole folder with all of it's contents. Below are some more details on what I have attempted in case someone can spot what I'm doing wrong.

If I add files to the folders using UI, Rider generates something like this in the .csproj:

<ItemGroup>
  <Content Include="TestAssets\Folder1\file1.txt"/>
  <Content Include="TestAssets\Folder1\file2.txt"/>
  ...
</ItemGroup>

If I replace this item group with

<ItemGroup>
  <Content Include="TestAssets\*">
    <CopyToOutputDirectory>Always</CopyToOutputDirectory>
  </Content>
</ItemGroup>

I can no longer see folders and files in Rider Solution Explorer (and they are not copied to output folder)

If instead of replacing auto-generate item group I just append the one above (with folder name and wildcard), I can see folders and files in solution explorer but they are still not being copied to the output directory.

Hm, changing Include attribute to

<Content Include="TestAssets\**">
  <CopyToOutputDirectory>Always</CopyToOutputDirectory>
</Content>

has worked. I was under impression that double asterisk means non-recursive wildcard, but I guess I was wrong.

With this notation I was able to remove individual auto-generated content entries.
