dotnet run gives error 0x80008096 (on 3.0.100-preview-009726, 009728, 009730)

[Lakritzator]

When doing a "dotnet new WinForms" or "dotnet new Wpf", followed by a "dotnet run" (or starting from VS) I get an error code -2147450730 (0x80008096)

Existing applications are also giving the same error, with 009726 the error is the same.
The last version which worked was 009722!

Don't know if it's related to #134, "does not work" can be anything. I think that one is just a version mismatch.

I also tested with 3.0.100-preview-009730, with this I have the same issue.

It must be a UI thing..

dotnet new WinForms
dotnet run

-> prompt comes back, echo %errorlevel% gives -2147450730 (0x80008096 )

This works fine:

dotnet new console
dotnet run

-> Hello World!

I cannot imagine this problem is a general thing, so let me know what I can do to give any more information.

Hi @Lakritzator,

To investigate this, can you try setting OutputType in the project file to Exe instead of WinExe and see if there's any diagnostics printed via dotnet run? We have an issue tracking the fact that apphosts set to "GUI" subsystem are not printing any needed error information when they fail to start (I can't find it, but I recall @nguerrera creating it...).

I suspect it can't find the runtime or a dependency to start, but it would be helpful to know which one :) We can move this issue to the appropriate repo once we have additional information, if necessary.

[Lakritzator]

Thanks for the quick hint, that should actually help us!

Changed WinExe to Exe, dotnet run now gives me the following output:

It was not possible to find any compatible framework version
The specified framework 'Microsoft.NETCore.App', version '3.0.0-preview1-26929-01' was not found.
  - Check application dependencies and target a framework version installed at:
      C:\Program Files\dotnet
  - Installing .NET Core prerequisites might help resolve this problem:
      https://go.microsoft.com/fwlink/?LinkID=798306&clcid=0x409
  - The .NET Core framework and SDK can be installed from:
      https://aka.ms/dotnet-download
  - The following versions are installed:
      2.0.9 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
      2.1.5 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]
      3.0.0-preview-27104-01 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App]

This actually looks identical to #134

[peterhuene]

Let me take a quick look at these builds on Windows and see what I can turn up.

[peterhuene]

Looks like Microsoft.DesktopUI.App is out of date and is referencing the older Microsoft.NETCore.App.

I'm going to dupe this to #134 and follow-up with the issue there. Thanks for reporting this!

[Lakritzator]

Now that I read the details and the information in #134, it probably works when someone doesn't delete all the previous versions and 3.0.0-preview1-26929-01 would still be available.

To test this, as 009722 worked, I installed this without removing the 009730,.
And voila a workaround, dotnet run works, now I can at least continue work.

So I have in my dotnet --info:

.NET Core SDKs installed:
  2.1.202 [C:\Program Files\dotnet\sdk]
  2.1.403 [C:\Program Files\dotnet\sdk]
  2.1.500-preview-009335 [C:\Program Files\dotnet\sdk]
  3.0.100-preview-009722[C:\Program Files\dotnet\sdk]
  3.0.100-preview-009730[C:\Program Files\dotnet\sdk]

[Lakritzator]

A much better workaround seems to be:
Modify the file Microsoft.DesktopUI.App.runtimeconfig.json in the directory: %PROGRAMFILES%\dotnet\shared\Microsoft.DesktopUI.App\3.0.0-alpha-27030-3

This should contain the version from the 3.0 directory in %PROGRAMFILES%\dotnet\shared\Microsoft.NETCore.App, in this case for me this is 3.0.0-preview-27104-01.

The resulting file looks like this:

{
  "runtimeOptions": {
    "tfm": "netcoreapp3.0",
    "framework": {
      "name": "Microsoft.NETCore.App",
      "version": "3.0.0-preview-27104-01"
    }
  }
}
