Can I claim a lower version of .NET than it really is?

Question

Sharepoint 2010 has version check in one place (also starting with some update WSS 3.0 also has this check):

...
Version version = Environment.Version;
if (version.Major > 2)
{
    ...
    throw new PlatformNotSupportedException(@string);

I know that I should not do this, but just out of curiosity - can this be overcome without writing a huge proxy?

Just out of curiosity, wondering if one can make any of this:

• adjust this check in the sharepoint dll at runtime to pass (the class that uses it is sealed and internal, if you're interested, this is the Microsoft.SharePoint.Administration.SPConfigurationDatabase class in Microsoft.Sharepoint.dll)

• temporarily overriding Environment.Version returns a value, for example:

  using (new EnvironmentVersionOverride("2.0")) { ... }

• in any other way?

: Environment.Version :

public static Version Version
{
  get
  {
    return new Version("4.0.30319.18444");
  }
}
