I try to add to a new project in Visual Studio 2017 a reference to the Web Service of Immediate Information Supply (SII) of the Spanish Tax Agency (AEAT) with the test environment URL.
From the solution explorer, I select the project, contextual menu add service reference, address " link "
Respond to the following error:
There was an error downloading ' link $ metadata'.
If I try with the advanced options, add a web reference, I request the certificate from the FNMT, I accept, and it returns the same error.
Is there anything that escapes me?
