Error:Unable to generate deps.json, it may have been already generated. You can specify the "-d" option before the tool name for diagnostic output (for example, "dotnet -d ": C:\Program Files\dotnet\sdk\2.1.401\Sdks\Microsoft.NET.Sdk\targets\GenerateDeps\GenerateDeps.proj

Hi @gicat
The error you are seeing comes from a NuGet package restore operation, the tool generates a project (the bootstrapper) and something is preventing the restoring of packages for this project.

Some suggestions:

• Do you have any custom nuget.config file under your project's directory? if so, can you copy it under the %temp% directory and try to add the web service reference again?
• Can you try it on a different machine?

Hi @mlacouture
I have solved it installing dotnet-svcutil

Install-Package dotnet-svcutil -Version 1.0.3

In fact launching the command

dotnet svcutil --additionalprobingpath "C:Users\XXXXX.nuget\packages" "C:Users\XXXXX\AppData\LocalTemp\WCFConnectedService\2018_Aug_31_08_58_24\SvcUtilParams.txt"

on command line, the result was:

No executable found matching command "dotnet-svcutil"

Thanks.

Hi @gicat
I'm glad you are unblocked. However, this tool is not designed to be installed as a project reference, this is the reason you are seeing the error message. You need to edit the project reference as below so it becomes a tool reference; additionally, the project needs to be restored. For more info refer to the tool guide.

<DotNetCliToolReference Include="dotnet-svcutil" Version="1.0.*" />

hope this helps,
