Question

When using UWP extension to open Consult app(.NET framework) will get (Error DEP0700: Registration of the app failed. [0x80073CF6] AppxManifest.xml(33，10): Error 0x80080204: Registration failed: b0b2f355-4232-447c-890a-feec3ec7ad4c_1.0.0.0_x86__hbnhee7zt39k0 package，because can't not find EntryPoint or StartPage )

in visual studio 2019.
in Windows10.

Using FullTrustProcessLauncher to lunch other app

protected async override void OnNavigatedTo(NavigationEventArgs e)
{
   base.OnNavigatedTo(e);

   if (ApiInformation.IsApiContractPresent("Windows.ApplicationModel.FullTrustAppContract", 1, 0))
   {
       await FullTrustProcessLauncher.LaunchFullTrustProcessForCurrentAppAsync();
   }
}

Cousule app start here

namespace CollectDataAP
{
    class Program
    {
        static private AppServiceConnection connection = null;

        static void Main(string[] args)
        {
            Console.ReadLine();

            InitializeWMIHandler();
            InitGlobalVariable();

            string tempForUWP = "", tempForOutput = "";

For side loading in Windows Application package project

 
      <Extensions>
        <uap:Extension Category="windows.appService">
            <uap:AppService Name="SampleInteropService" />
        </uap:Extension>
        <desktop:Extension Category="windows.fullTrustProcess" Executable="CollectDataAP\CollectDataAP.exe" />
      </Extensions>

File structure

When I redo this this UWP project and just only side-loading Console App. it can normally run. Can give me some direction?

Answer 1

Just commend
in Package.appxmanifest

<Extensions>
    <uap:Extension Category="windows.appService">
        <uap:AppService Name="SampleInteropService" />
    </uap:Extension>
  <desktop:Extension Category="windows.fullTrustProcess" Executable="CollectDataAP\CollectDataAP.exe" />
</Extensions>

Remove all project except UWP

commend await FullTrustProcessLauncher.LaunchFullTrustProcessForCurrentAppAsync();

And compiler, only show UWP.

Than revert to original can sove this problem.

Answer 2

Move all app and compile. Than, link UWP and compile. Than, link sideload app and compile. enter image description here
