Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.1

Environment

  • Windows Vista x64, or Windows 7 x64
  • Visual Studio 2010
  • Crystal Reports for Visual Studio 2010, RTM (13.0.0.99)
  • .NET Web Application Project

Reproducing the Issue

  1. Create a new Web Application Project in Visual Studio 2010.
  2. Make sure it is a File System web site, not running on IIS.
  3. Add a CrystalReportViewer control, or Crystal Report to the project.
  4. Attempt to preview the web site.

Cause

  • Errors like this are caused because the Web Application is built to target x64 or Any CPU.
  • The built in web server used for File System web applications, called Cassini (WebDev.WebServer40.exe), is a 32 bit application.
  • When x64 or Any CPU are selected as the platform target the 32 bit WebDev.WebServer40.exe attempts to load 64 bit assemblies and other images into a 32 bit memory space and errors occur.

Resolution

  • The File System web applications can't be used in x64 or Any CPU mode on a 64 bit operating system.
  • Ensure your Platform target is set to x86 on your development server if you are going to use File System web sites.
  • To change your Platform target:
    1. Open the Solution Explorer in Visual Studio.
    2. Right click your Project and select Properties.
    3. Click the Build tab.
    4. Set the Platform target to x86.
