RazorLight

I am trying to generate HTML based on a .cshtml file, which is embedded:

<EmbeddedResource Include="Templates\ReportTemplate.cshtml" />

However, from RazorLight I always get the following Exception:

RazorLight.TemplateNotFoundException: Project can not find template with key My.Namespace.Application.Templates.ReportTemplate.cshtml
      at RazorLight.Compilation.RazorTemplateCompiler.CreateRuntimeCompilationWorkItem(String templateKey)
      at RazorLight.Compilation.RazorTemplateCompiler.OnCacheMissAsync(String templateKey)
      at RazorLight.Compilation.RazorTemplateCompiler.CompileAsync(String templateKey)
      at RazorLight.EngineHandler.CompileTemplateAsync(String key)
      at RazorLight.EngineHandler.CompileRenderAsync[T](String key, T model, ExpandoObject viewBag)

But when I check the embedded resources, I can clearly see the embedded resource :

string[] files = Assembly.GetExecutingAssembly().GetManifestResourceNames();
files contains: My.Namespace.Application.Templates.ReportTemplate.cshtml

Here is my code to generate the PDF:

private async Task<string> RenderRazorTemplate(string key, Type viewModelType, object viewModel)
        {

            string[] files = Assembly.GetExecutingAssembly().GetManifestResourceNames();
            var engine = new RazorLightEngineBuilder()
                .UseEmbeddedResourcesProject(Assembly
                .GetExecutingAssembly()) // Use the Executing Assembly as project that embeds the .cshtml templates
                .SetOperatingAssembly(viewModelType.Assembly) // Without this, you'll get a Exception saying that the Assembly can't find the AntiForgery.dll
                .UseMemoryCachingProvider()
                .Build();
            
            return await engine.CompileRenderAsync(key, viewModel);
        }

My parameters are:
Key: My.Namespace.Application.Templates.ReportTemplate.cshtml

I am using RazorLight.NetCore3 Version 3.0.2

I am using RazorLight.NetCore3 Version 3.0.2

That's not an official package. You can see what they are doing differently from us here: https://www.fuget.org/packages/RazorLight.NetCore3/3.0.2 and https://www.fuget.org/packages/RazorLight/2.0.0-rc.3 and comparing the nuspec files.

The latest rc.3 actually has support for debugging why you can't find a template. Read the release notes.
