There is no way to make an application to run as admin by default

See original GitHub issue

I’m trying to get an always-admin executable with .net Core. I’m new to this, so please bear with me.

The “published” executable doesn’t contain the application manifest I specified in the csproj file, instead that manifest is embedded in the DLL. This means that there is no way to always request elevation via UAC prompt.

This has been checked with the following commands executed in a WSL console:

Command: strings ConsoleApp1.exe | grep requestedExecutionLevel Output: <requestedExecutionLevel level='asInvoker' uiAccess='false' /> Command: strings ConsoleApp1.dll | grep requestedExecutionLevel Output: <requestedExecutionLevel level='requireAdministrator' uiAccess='false' />

Reproduced with:

Build command: dotnet publish -r win10-x64

C# code:

static bool isAdmin()
{
        return new WindowsPrincipal(WindowsIdentity.GetCurrent()).IsInRole(WindowsBuiltInRole.Administrator);
}

.csproj contents:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp2.0</TargetFramework>
    <ApplicationManifest>app1.manifest</ApplicationManifest>
  </PropertyGroup>
  <ItemGroup>
    <PackageReference Include="System.Security.Principal.Windows" Version="4.4.0" />
  </ItemGroup>
</Project>
