c# – 无法建立连接,因为目标计算机主动拒绝它127.0.0.1:8000

当尝试在客户端应用程序中添加URL(net.tcp：// localhost：8000 / UserManagement)时,我收到错误：

Metadata contains a reference that cannot be resolved:
‘net.tcp://localhost:8000/UserManagement’. Could not connect to
net.tcp://localhost:8000/UserManagement. The connection attempt lasted
for a time span of 00:00:00.9531433. TCP error code 10061: No
connection could be made because the target machine actively refused
it 127.0.0.1:8000. No connection could be made because the target
machine actively refused it 127.0.0.1:8000 If the service is defined
in the current solution,try building the solution and adding the
service reference again.
