Install nupkg to Local Nuget Store

1. create a folder c:\temp\nuget
2. Install nupkg in this folder: nuget add mypackage.0.0.0.nupkg -source c:\temp\nuget
3. In Visual Studio (2019), add this folder to the avialable nuget servers

Get nuget from protected server

nuget install My.Cool.Nuget -source https://some.where.azure.com/company/_packaging/product/nuget/v3/index.json

Config available Nuget Servers in Solution

Add this a config file: .nuget\NuGet.Config in the folder where .sln sits

Example config file:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <solution>
        <add key="disableSourceControlIntegration" value="true" />
    </solution>
    <packageRestore>
        <add key="enabled" value="True" />
    </packageRestore>
  <packageSources>
    <add key="server1" value="https://tfs.myserver.org/tfs/ABC/_packaging/DEF/nuget/v3/index.json" />
    <add key="server2" value="https://tfs.myserver.org/tfs/ABC/_packaging/GHI/nuget/v3/index.json" />
  </packageSources>
</configuration>

Create .NET Standard nuget

Example for nuget config in csproj:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>netstandard2.0</TargetFramework>
  </PropertyGroup>
  
 <PropertyGroup>
    <!-- where should the nuget package be created at -->
    <PackageOutputPath>./nupkg</PackageOutputPath>
    
    <!-- nuget related properties -->

nuget pack

• use 'nuget pack' for .net framework
• use 'dotnet pack' for .net Standard and .net core (first: convert csproj to sdk-style and Migrate from packages.config to PackageReference)

examples

nuget.exe pack .\myApp\myProj.csproj -NonInteractive -OutputDirectory c:\temp\nuget -Properties Configuration=Release -IncludeReferencedProjects -Verbosity normal

"The -IncludeReferencedProject flag only really makes sense when your project is managing dependencies via packages.config file." According NuGet/Home#5720

dotnet pack .\myApp\myProj.csproj --output c:\temp\nuget --configuration Release --verbosity normal

Error NU5014 in nuget pack

running this statement:

nuget.exe pack .\myApp\myProj.csproj -NonInteractive -OutputDirectory c:\temp\nuget -Properties Configuration=release -IncludeReferencedProjects -Verbosity normal

Referencing a .net Standard project gives this error:

Error NU5014: Error occurred when processing file 'C:\Work.proj\myApp\myProj.csproj': Unable to find 'bin\release\myApp\bin\release'. Make sure the project has been built.

Options to solve this issue:

• refrence the .net Standard package by nuget, not by project reference
• in my case, the b.dll had to refrence c.dll as nuget package reference, not as project reference: a.dll -> b.dll -> c.dll if nuspec ist there, make sure the following depencency gets added to your nuspec in the nuget. If not, add this lines to nuspec (not needed: had been generated in my case)

   <dependencies>
     <dependency id="myProj" version="2.0.0" />
   </dependencies>

• remove argument -IncludeReferencedProjects (usually not recommended, because we usually want the references included)
  • "The -IncludeReferencedProject flag only really makes sense when your project is managing dependencies via packages.config file."
    • according NuGet/Home#5720
• check open issue: NuGet/Home#3891 (closed, but not fixed: dotnet/sdk#6688)

Create your own nuget server

Tipps and Tricks

Reinstall packages

After updating framework or installing or updating nugets, it is reccommended to reinstall all packages:

Update-Package -Reinstall
Update-Package -Reinstall -ProjectName Project.Name.Here
Update-Package Package.Name.Here -Reinstall -ProjectName Project.Name.Here

Binding

Binding redirects are added if your app or its components reference more than one version of the same assembly.

https://docs.microsoft.com/en-us/dotnet/framework/configure-apps/how-to-enable-and-disable-automatic-binding-redirection?redirectedfrom=MSDN

Clear all local caches

In case of any nuget issues, clear all local nuget folders:

• dotnet nuget locals all --clear
• nuget locals all -clear

More details about managing folders: https://docs.microsoft.com/en-us/nuget/consume-packages/managing-the-global-packages-and-cache-folders

install/restore error: Cycle detected

Do not use the same name for folder and package (example: dotnet add package IdentityServer4 in Folder \IdentityServer4)

c:\Work.proj\IdentityServer4>dotnet add package IdentityServer4
  Determining projects to restore...
  Writing C:\Users\bop\AppData\Local\Temp\tmp4852.tmp

nuget pack error

• Use the latest version of nuget.exe (Azure DevOps: use "Nuget Tool Installer")
• for .net Standard, use dotnet pack

nupkg contains source files instead of bin

Wrong argument: give csproj-file instead of nuspec-file

Error 401 Unauthorized

Login Visual Studio with target account (try to disable vpn first)

Linux

Slow? performance issues? check this: Starting with .NET 8 SDK, verification is enabled by default. To opt out, set the environment variable DOTNET_NUGET_SIGNATURE_VERIFICATION to false.
