Sharepoint Object Model C# Error The Web Application at could not be found. Verify that you have typed the URL correctly

By peter.stilgoe

Hello there! If you are new here, you might want to subscribe to the RSS feed for updates on this topic.

When running some C# code containing a reference to SPSite ie

        string siteUrl = "http://devapp01/";
        using (SPSite spSite = new SPSite(siteUrl))

I was getting the following error:

The Web Application at 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.

Looking at various forums people have spent along time troubleshooting this problem, in my case it was easily fixed by:

Go to Project Properties -> Build -> Target Platform -> Make it Any CPU (default is x86)
