SharePoint 2010 Console Application System.IO.FileNotFoundException Error

I created a new console application to test some code snippets for SharePoint 2010 in Visual Studio 2010.

It threw the following error:

System.IO.FileNotFoundException was unhandled
Message=The Web application at http://demo/ could not be found. Verify that you have typed the URL correctly. If the URL should be serving existing content, the system administrator may need to add a new request URL mapping to the intended application.

What a striking error! FileNotFound?

The issue is that, as we already know, SharePoint 2010 only runs in x64 bit and thus we only have 64-bit code on our machine. The default console application template in Visual Studio has a default of x86. If we change our Build platform target, we’ll get past this FileNotFound error.

Right-click the Project, select Properties, and on the Properties canvas, click the build tab. Change the platform target to Any (or x64 if you prefer).

    Hi david,
    I’ve followed your instructions but I am still having the FileNotFound error. Any idea?

  5. RC says :

    I’ve done that as well and the dll looks fine.

    Since I need to target the .NET framework 3.5 what I want to try is to install VC 2008 and build a new project from there. What do you think??

  6. RC says :

    I meant VS (Visual Studio) 2008.

  7. RC says :

    Thanks very much for your assistance!!!
