At present, the expanding capacity of the Workflow Management System is weak. And these systems can't be rallied easily. This paper investigates the workflow technology under the .NET Framework and the application of it in the material management system.Firstly, this paper investigates the workflow reference model which is offered by WFMC and provides the structural model of Workflow Management System under the Framework Net. Based on building Workflow Management System under the framework Net, this paper investigates the integrative manner of the distributed Workflow Management System.Secondly, through the investigation on metal model of the workflow management system which is offered by WFMC and combining the features of .NET technology, the author of this paper put a kind of modified metal model forward which is used for defining process .This model makes it easier for the amendment of process definition, its structural relation and restrictive qualifications of activities. Then, integrating the modification of metal model, this paper has enlarged the language which is used for defining workflow process.Lastly, According to the feature of .NET technology, the author of this paper explores a kind of workflow engine which is stable, expandable, and safe.The investigative harvest of this paper, used in the development of material management system under the .NET Framework, can manage distributed business well and change the process of business neatly. In addition, it can easily rally the present systems of enterprises .So it can easily fulfill the requirements of key business.
