I’ve a strange problem..I’m trying to build a pipeline in Azure DevOps for a .net project and trying the below options which are not fruitful, Need your thoughts on this.

I’m trying to build a solution file (.sln) for a .net project in Azure DevOps. The source control used is TFVC, we have a build server, azure DevOps agent installed on it and it’s running with Network service account.

Option 1

Running the task locally to get the packages mentioned in packages folder in nuget.config

Output – It’s not picking my mentioned packages path in nuget.config file instead it is picking C:Program Filesdotnetlibrary-packs

option 2

Our build server doesn’t access the Internet, So I’m trying to enable the proxy setting for IE using below script in azure DevOps pipeline using powershell task – Passing proxy server and by passlist in arguments list

Still this option also doesn’t work and its stats below **Erroras running the ‘restore’ operation with an ‘HTTP’ source: we don’t have certificate and when tried to apply a wildcard cert, unable to update the bindings- for http port used is 8080 and for https- “443 is not working”.

Option 1 -Running the task locally to get the packages mentioned in packages folder in nuget.config

For it I’ve created a “dotnet restore” task having below details

Display name – Restore Command- restore Path to projects- **/*.sln Feeds and authentication – Feeds to use I selected – Feeds in my NuGet.config Mentioned my nuget.config path (placed config file in the build server path)

**Nuget.config **

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageRestore>
    <add key="enabled" value="False" />
    <add key="automatic" value="False" />
  </packageRestore>
  <bindingRedirects>
    <add key="skip" value="False" />
  </bindingRedirects>
  <packageManagement>
    <add key="format" value="0" />
    <add key="disabled" value="False" />
  </packageManagement>
  <packageSources>

      <add key="Microsoft Visual Studio Offline Packages" value="E:packages" />

  </packageSources>
</configuration>

Packages folder has all the required packages in the path.

When I try to run the task, it is picking the path – It throws error stating as below

error NU1101: Unable to find package Microsoft.NETCore.App.Ref. No packages exist with this id in source(s): C:Program Filesdotnetlibrary-packs, Microsoft Visual Studio Offline Packages error NU1102: Unable to find package Microsoft.WindowsDesktop.App.Ref with version (= 6.0.30) error NU1102: – Found 1 version(s) in Microsoft Visual Studio Offline Packages [ Nearest version: 6.0.31 ] error NU1102: – Found 0 version(s) in C:Program Filesdotnetlibrary-packs error NU1102: Unable to find package Microsoft.AspNetCore.App.Ref with version (= 6.0.30)

It’s not picking my mentioned packages path in nuget.config file instead it is picking C:Program Filesdotnetlibrary-packs

Note- The above-mentioned packages 6.0.30 and 6.0.31 are placed in the “E:packages”

option 2:

Our build server doesn’t access the Internet, So I’m trying to enable the proxy setting for IE using below script in azure DevOps pipeline using powershell task – Passing proxy server and by passlist in arguments list

First Task – Proxy enable script

param ( [string]$ProxyServer, [string]$BypassList )

Set the execution policy

Set-ExecutionPolicy -ExecutionPolicy Unrestricted -Scope CurrentUser -Force

Function to run command as administrator

function Run-AsAdmin { param ( [string]$command )

$processInfo = New-Object System.Diagnostics.ProcessStartInfo
$processInfo.FileName = "powershell.exe"
$processInfo.Arguments = "-Command `"& { $command }`""
$processInfo.Verb = "runas"
$processInfo.WindowStyle = "Hidden"

$process = New-Object System.Diagnostics.Process
$process.StartInfo = $processInfo

try {
    $process.Start() | Out-Null
    $process.WaitForExit()
} catch {
    Write-Error "Failed to run as administrator: $_"
}

}

Set the proxy settings

$proxyCommand = "netsh winhttp set proxy $ProxyServer bypass-list=$BypassList" Run-AsAdmin -command $proxyCommand Write-Host "Proxy settings: HTTP_PROXY=$ProxyServer , bypass-list=$BypassList"

Verify the settings

Run-AsAdmin -command "netsh winhttp show proxy"

The Output shows the proxy server and Bypasslist details, not sure if the above is really enabling the proxy.

**Second Task – dotnet core**

Display name – Restore

Command- restore

Path to projects- **/*.sln

Feeds and authentication – Feeds to use I selected – Feed(s) I select here

Use packages from this Azure Artifacts feed- Created a feed in Azure Artifact – BuildPackages

checked -Use packages from NuGet.org

**Nuget.config**

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageRestore>
    <add key="enabled" value="False" />
    <add key="automatic" value="False" />
  </packageRestore>
  <bindingRedirects>
    <add key="skip" value="False" />
  </bindingRedirects>
  <packageManagement>
    <add key="format" value="0" />
    <add key="disabled" value="False" />
  </packageManagement>
  <packageSources>

      <add key="nuget.org" value="https://www.nuget.org/api/v2/" /> 
      <add key="nuget.org" value="https://api.nuget.org/v3/index.json" />

  </packageSources>
</configuration>

Still this option also doesn’t work and it stats below **Error:**

error NU1302: You are running the ‘restore’ operation with an ‘HTTP’ source: http://<tfsurl>_packaging/BuildPackages/nuget/v3/index.json. NuGet requires HTTPS sources. To use an HTTP source, you must explicitly set ‘allowInsecureConnections’ to true in your NuGet.Config file. Please refer to https://aka.ms/nuget-https-everywhere for more information.

Please let me know what changes needs to be done.

Appreciate your help!
