Answer 1

this worked for me, link . From github user @danilobreda

Below is the answer from the link above:

What worked for me... using the PAT token.

My dockerfile:

FROM microsoft/aspnetcore-build:latest AS build
WORKDIR /src
COPY . .
COPY NuGet.Config ./
RUN dir
RUN dotnet restore --configfile NuGet.Config -nowarn:msb3202,nu1503 --verbosity diag
RUN dotnet publish --output /output --configuration Release

FROM microsoft/aspnetcore:latest
WORKDIR /app
COPY --from=build /output /app
ENTRYPOINT ["dotnet", "DockerProject.dll"]

and my NuGet.Config file:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
    <add key="BredasVSTS" value="https://xxxx.pkgs.visualstudio.com/_packaging/BredasVSTS/nuget/v3/index.json" />
  </packageSources>
  <packageSourceCredentials>
    <BredasVSTS>
      <add key="Username" value="emailhere" />      
      <add key="ClearTextPassword" value="PAT here" />
    </BredasVSTS>
  </packageSourceCredentials>
</configuration>

The Username parameter need to be passed but you can set a random username/phrase there... since PAT does not have username parameter. Make sure that the nuget package have permissions (read and write) of PAT owner.

Answer 2

Re-entering account credentials in VS worked for me.

Answer 3

Repair Visual Studio installation worked for me.
