Method not found: 'System.String RazorEngine.Templating.ITemplate.Run

Question

I'm trying the new Azure Mobile App. Created the instance in Azure, and then downloaded the Visual Studio package. Updated all components via Nuget. And now when I run it, am getting following error :

<Error><Message>An error has occurred.</Message><ExceptionMessage>Method not found: 'System.String RazorEngine.Templating.ITemplate.Run(RazorEngine.Templating.ExecuteContext)'.</ExceptionMessage><ExceptionType>System.MissingMethodException</ExceptionType><StackTrace>   at Microsoft.Azure.Mobile.Server.Content.HtmlActionResult.ExecuteAsync(CancellationToken cancellationToken)

Found another post that recommends to upgrade Windows Azure Mobile Services, which I have done so.

Am running Razor Engine 3.7.0

Answer 1

This seems to be an issue with RazorEngine v 3.5 and above. Working fine with 3.4.2.
