For EG 4.1, you must use .NET 1.1. Unfortunately you cannot target .NET 1.1 with VS2008 or VS2005, even the express editions. You need VS2003, which does not have a free express edition.<BR /> <BR /> Our next release supports .NET 2.0, and you can use .NET 2.0, 3.0, and 3.5 to create custom tasks.<BR /> <BR /> Chris Thu, 13 Mar 2008 18:27:57 GMT https://communities.sas.com/t5/SAS-Enterprise-Guide/add-in-custom-tasks/m-p/7449#M2361 ChrisHemedinger 2008-03-13T18:27:57Z
