We have email templates as .cshtml file format in under the Content/Templates folder. We read that template using File.ReadAllText() then apply our model value then send that mail to the particular user. It works fine in locally hosted machine. When I host my asp.net mvc app in Azure App service file not found exception throws.

private string GetTemplateContent(string templatePath)
    {
        var templateContent = string.Empty;
        var path = GetAbsoluteTemplatePath(templatePath);

        try
        {
            templateContent = File.ReadAllText(Path.GetFullPath(path));
        }
        catch (Exception ex)
        {
            Log exception
        }

        return templateContent;
    }

Path in Azure "D:\home\site\wwwroot\Content\Templates\ScheduleTemplate.cshtml"

I ensured file exist in that location.

Can you help me why this is happening?

This is Azure App service issue. From this Thread we found the solution. Add node in Application Setting
