Sir

We have seen Srivatsan24 article about using enterprise library 4.1 in sharepoint. It was very nice article.
We have done the same setting in sharepoint 2007 for Enterprise library 5.0 . For .net applications we haven't faced any problem, but if we are using infopath forms, it is showing in preview but We are not able to deploy We are getting this error.
