Error: Unable to generate deps.json, it may have been already generated. when adding a Service reference to Xamarin forms

Question

I have a Xamarin forms v3.1 project with the .NET standard approach. I tried to add a reference to a web service I have using "add connected service" and then from the pop up, I choose Microsoft web service reference provider.

I add the web service link, Visual Studio (2017 v15.8) discovers its structure, and then when I click finish, it takes a while but then shows this 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\2.1.400\Sdks\Microsoft.NET.Sdk\targets\GenerateDeps\GenerateDeps.proj
Done.

Any idea why this is happening and how to solve this issue?

is there already a deps.json file somewhere in your folder structure? — Jason, Sep 27 '18 at 20:59
Possibly a permissons error: some bugs filed [here](https://github.com/dotnet/sdk/issues/2128) and [here](https://github.com/dotnet/cli/issues/8981). Post suggesting that opening up pemissions to directory may [work](https://github.com/dotnet/cli/issues/8981#issuecomment-378404548) — Andrew, Sep 27 '18 at 21:55
i tried adding permissions for everyone account on the sdk folder but the issue still happens — a.tolba, Sep 27 '18 at 22:43

Execute tool-line command:

dotnet tool install --global dotnet-svcutil

What worked for me was running the "dotnet restore" command in VS 2019.

When I add a service reference to a regular.net core web application, I got the same error. After the investigation I came to know that, somehow svcutil was not installed. Once I installed svcutil using Nuget Package Manager (Install-Package dotnet-svcutil), this issue resolved.

For a .NET Core 2 application you cannot install dotnet-scvutil ver 2.0.1. For me it worked with ver 1.0.4.

After you install this you need to update rest of the NuGet packages except dotnet-svcutil.
