Cannot publish ASP.NET Web API to Azure App Service (with SwashBuckle)

Question

I have an App Service that has been running in Azure for a while. I have just updated it to .NET 6.0 (and installed Swashbuckle.aspnetcore.cli v6.2.3 locally).

I cannot publish to Azure. When I first tried it told me it couldn't find aspnetcore3.0 and the only installed versions it could find were .NET 5.1.4 and .NET 6.0.1.

Following instructions here: https://github.com/domaindrivendev/Swashbuckle.AspNetCore/issues/1485

I added a global.json to my project:

{
    "sdk":
    {
        "version": "6.0.1",
        "rollForward": "latestPatch"
    }
}

Now when I try and publish I get the following error:

    Failed to install DotNet CLI tool 'swashbuckle.aspnetcore.cli'.  Error dotnet tool restore

Could not execute because the application was not found or a compatible .NET SDK is not installed.
Possible reasons for this include:
  * You intended to execute a .NET program:
      The application 'tool' does not exist.
  * You intended to execute a .NET SDK command:
      A compatible installed .NET SDK for global.json version [6.0.1] from [C:\Projects\MyProject\global.json] was not found.
      Install the [6.0.1] .NET SDK or update [C:\Projects\MyProject\global.json] with an installed .NET SDK:

How can I publish my app service?

Answer 1

To anyone else that finds this issue, I finally fixed it by editing the file "dotnet-tools.json" in the ".config" folder in the project root folder, and changing the version of swashbuckle.aspnetcore.api from 5.6.3 to 6.3.0.

I also updated to swashbuckle 6.3.0, and changed global.json to be:

{
    "sdk":
    {
        "version": "5.6.3",
        "rollForward": "latestMajor"
    }
}

Note the use of latestMajor rather than latestPatch.
