Hi all, I'm looking for a way to automate the deployment of a custom CAS policy in SharePoint. What i would like to achieve is the following: All assemblies that have been built and signed by our build server (with a secret key) should run in SharePoint under the 'higher than normal' trust level. Now I can manually edit the cas policy files to include something like this: <CodeGroup class="UnionCodeGroup" version="1" PermissionSetName="MyPermissionSet" Name="[My Company public key]" Description="Grants all "> <IMembershipCondition class="StrongNameMembershipCondition" version="1" PublicKeyBlob="[public key goes here]" /> </CodeGroup> And that works great. However, we have several huge sharepoint farms, with many applications running on it. I'd like to avoid having to manually edit all policy files to include this xml snippet. Is there a way to automate this? For example, from a feature? With kind regards, Erwin van der Valk
