Problem:
If you follow the "Working with COBOL Projects with .NET" tutorial and get at the steps for adding a Web reference, you may get prompted to open or save after clicking on the Service1 link from the Add Web Reference wizard.
Resolution:
This problem may actually occur with any service that is selected from the Add Web Reference wizard. This simply means that the file name extension (.asmx) was not mapped to any program or interpreter that processes that file type.
Here are the steps to map that file name extension to the program or interpreter:
1. Find out if there are different versions of the MS .NET Framework installed on the machine
2. Determine which one (if there are more than one version) is the latest version by looking at the directory name (e.g. C:\\[Windows directory]\\Microsoft.NET\\Framework\\v1.1.4322 is more recent than C:\\[Windows directory]\\Microsoft.NET\\Framework\\v1.0.3705)
3. Open a command prompt session
4. Go to the directory where the latest version is at
5. Execute the following commands:
aspnet_regiis.exe -i<enter>
iisreset /restart<enter>
