Could not resolve template

[tbconrad]

I have a console application that uses RazorEngine to send email based on the run of the application. I am successfully able to send emails both in the development IDE and from running the console application via the executable. However, when I run the console application from a scheduled task I receive an error "Could not resolve template" on line, var emailHtmlBody = Engine.Razor.RunCompile("ResponseErrors.cshtml", null, model);

has anyone run into this?

     var config = new TemplateServiceConfiguration
     {
        TemplateManager = new ResolvePathTemplateManager(new[] {"EmailTemplates"}),
        DisableTempFileLocking = true
     };

     Engine.Razor = RazorEngineService.Create(config);
     var emailHtmlBody = Engine.Razor.RunCompile("ResponseErrors.cshtml", null, model);

UPDATE 1:

• The server that is executing the scheduled task is the same server where the console app resides.
• The account that is executing the console app in the Scheduled Task is a domain account with local admin rights to the server.

UPDATE 2: There is no RazorEngine... folder that was created in the user's temp folder.

Perhaps the scheduled task has no sufficient permission to read from folder where template is?

@csimone86 I thought that too but the account is a local administrator on the server and the templates are in the application folder.

So I was able to reproduce this. I created a sample console app and put it up on GitHub as RazorEngine_Test. Compile and run the project and it will run successfully from the debug or release folder. Copy all the files from the folder you ran it from and paste them into a new folder then run it again.

UPDATE 3: It seems that the TemplateServiceConfiguration is not working as designed or the examples I worked off of are incorrect. I updated the test project with the 2 lines below and that solved my issue. I don't think this was the intended implementation method but it works. Posting because I know someone will run into the same issue.

var config = new TemplateServiceConfiguration
{
    TemplateManager = new ResolvePathTemplateManager(new[] {"EmailTemplates"}),
    DisableTempFileLocking = true
};

Engine.Razor = RazorEngineService.Create(config);

//new
string path = AppDomain.CurrentDomain.BaseDirectory;
string filePath = $"{path}EmailTemplates\\ExceptionEmail.cshtml";
//

var emailHtmlBody = Engine.Razor.RunCompile(filePath, null, model);

Perhaps are you in an Isolated (hosted) environment? I do not know exactly what I mean... I mean, is there a process that run you code?

Perhaps the base directory you see is the directory where the exe of the process that run your code reside... so you need to force it

@csimone86 No isolated or hosted environment, just an on-prem server trying to run a console application from a local administrator account
