.NET download file REST SOE
This sample illustrates how to develop a REST server object extension (SOE) with the capability of downloading server resources. The SOE generates a text file on the Server and allows clients to download the file from the Server. It also provides REST endpoints to manage those files such as obtaining file names and deleting the files.
Deploying the SOE from the .soe file (
..\bin\Release\DownloadFileRESTSOE_ent.soe) does not require you to open Visual Studio. However, you can load the project (
..\DownloadFileRESTSOE\DownloadFileRESTSOE.csproj) in Visual Studio to debug, modify, and recompile the SOE code.
