Determining and changing the .NET version
If you get errors when using a .NET object in your application, you could have version issues. For example, many
Microsoft system classes were added in .NET Version 2.0, including System.IO.DriveInfo and
System.Net.NetworkInformation.Ping. For examples of these classes in applications, see
page 1163 and
"Example: Using a .NET class

<cffunction name="GetDotNetVersion" returntype="string">
<cfset var seClass="">
<cfobject type=".NET" name="seClass" class="System.Environment">
<cfreturn seClass.Get_Version().ToString()>
</cffunction>
If the function reports that the active version is not the one you require, install or reinstall the correct version of the
.NET framework redistributable package on the system that runs ColdFusion. Then reinstall the ColdFusion .NET
extension so that it uses the correct .NET version.

ColdFusion .NET service. You can also run the .NET extension agent as an application.

a J2EE or multiserver configuration, it is in the .NETInstallDir\jnbridge directory, and the default installation
directory is C:\ColdFusonDotNetExtension.
