How do I set full trust for a single Web Part in SharePoint?

I am looking to set full trust for a single web part, is this possible? manifest.xml maybe?

From stackoverflow naspinski

• Have you tried registering the assembly in the GAC? This is the preferred approach to giving any assembly full trust on your machine:

  gacutil.exe \i C:\Path\To\Dll.dll
  

  Hope that helps. Let me know if I misunderstood your question.

  naspinski : I am deploying my custom made webparts with a CAB file and 'stsadm -o addwppack', will this be in the GAC? How can I check?

  Ryan : naspinski - probably better to edit your question to clarify the CAB package, people may not see your comment here
  From Ed Altorfer

• You can install a CAB packaged web part to the GAC using

  STSADM -o addwppack -filename yourwebpart.cab -globalinstall
  

  If you are using WSP packages you need to set attributes in the manifext.xml file

  <Assembly Location="yourassembly.dll" DeploymentTarget="GlobalAssemblyCache">
  

  and call

  STSADM -o AddSolution -filename yourwebpart.wsp
  
  STSADM -o DeploySolution -name yourwebpart.wsp -allcontenturls -immediate -force -allowGacDeployment
  

  Of course you shouldn't really install to the GAC if you can help it, setting CAS is the preferred way.

  From Ryan

• As far as I recall manifest.xml is correct, and you specify the CodeAccessSecurity.

  This article has a detailed description about it http://www.dotnetmafia.com/blogs/dotnettipoftheday/archive/2007/07/05/how-to-configure-code-access-security-for-a-web-part.aspx

  when you deploy your solution then you deploy it with the -allowCasPolicies flag on

  I'm not sure i'd want to put a webpart into the GAC
