Service Stack Razor View Not Found - servicestack

Question

I added the RazorPlugin along with a Test.cshtml in the root View folder (tried wwwroot as well along with TestGet.cshtml). This is an donet Core project. Whenever browsing to: /api/test the following error is generated:
Snapshot of TestGet generated by ServiceStack on 6/3/2017 4:20:40 PM

The other formats work (json/etc).

I've created a minimal verifiable MVC test project to simulate your configuration which is working as expected at: https://github.com/NetCoreApps/scratch/tree/master/src/RazorApi
It includes the same Test Services, (sans [Authenticate] attribute):
public class Test
{
public string ExternalId { get; set; }
}
[Route("/test")]
public class TestGet : IGet, IReturn<Test>
{
}
public class TestService : Service
{
public Test Get(TestGet request)
{
var test = new Test { ExternalId = "abc" };
return test;
}
}
And the minimal AppHost configuration which just sets the HandlerFactoryPath to api and registers ServiceStack's RazorFormat plugin:
public class AppHost : AppHostBase
{
public AppHost()
: base("ServiceStack + .NET Core", typeof(MyServices).GetTypeInfo().Assembly) {}
public override void Configure(Funq.Container container)
{
SetConfig(new HostConfig
{
HandlerFactoryPath = "api",
DebugMode = true,
});
Plugins.Add(new RazorFormat());
}
}
With the Test.cshtml maintained in /Views/Test.cshtml:
#model Test
#{
Layout = "_Layout";
}
<h1>Test.cshtml</h1>
<p>#Model.ExternalId</p>
Which works as expected with the Razor View executed when calling:
http://localhost:5000/api/test
Which also works when renamed to match the Request DTO at TestGet.cshtml.
As the issue seems specific to your project I'd compare your layout with bare RazorApi Github Project to see if you can find any differences, failing that I'd recommend commenting out configuration to get it to a working state then uncomment sections at a time to find out which configuration is causing the issue.
