Q:

ASP.Net Core exclude published language directories other than english

I publish my ASP.Net Core 3.1 Server like this:
dotnet publish --configuration Release --runtime win7-x64 -p:PublishTrimmed=true --output c:\MyServer

What I get in c:\MyServer is a lot of international language directories: cs, de, es, fr, zh-hans etc
How can I publish with only the English version ?
I tried using ExcludeFoldersFromDeployment in my csproj:
  <PropertyGroup>
    <TargetFramework>netcoreapp3.1</TargetFramework>
    <RuntimeIdentifier>win7-x64</RuntimeIdentifier>
    <IsTransformWebConfigDisabled>true</IsTransformWebConfigDisabled>    
    <AspNetCoreHostingModel>inprocess</AspNetCoreHostingModel>
    <Nullable>enable</Nullable>
    <ExcludeFoldersFromDeployment>cs;de;es;fr;he;hi;it;ja;ko;nl;pl;pt;ru;tr-TR;zh-Hans;zh-Hant</ExcludeFoldersFromDeployment>
  </PropertyGroup>

But that didn't help
Any help ?

A:

You get a lot of language folders containing CodeAnalysis.dll files in your published output if you have a project reference to Microsoft.VisualStudio.Web.CodeGeneration.Design, which is needed for scaffolding controllers. If that is true for your project, change the package reference in your .csproj file to include ExcludeAssets="All":
<PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Design" Version="3.1.1" ExcludeAssets="All"/>
