I did the following:
Create a new F# project in VS2013
In Package Manager Console, execute while targetting the new project:
Install-Package FSharp.Azure.StorageTypeProvider
In the file, type:
open FSharp.Azure.StorageTypeProvider
...as can be seen in the examples included in the Github project.
But I get the error:
"The namespace or module 'FSharp' is not defined"
What am I doing wrong? I am new to Nuget, and this is the first package I've downloaded that hasn't "just work"ed.
My project was targeting .NET framework 4.5 by default. It needed to be targeting 4.5.1.

I've following structure for a .NET Framework project:
-->ProjectSoln -------->ClassLibProj1 -------->ClassLibProj2 -------->ConsumerLibProj3
I've defined GlobalAssemblyInfo.cs file at solution level and added the reference to this file in all
the 3 projects. ConsumerLibraryProj3 has project reference to ClassLibraryProj1 and ClassLibraryProj2.
I've added nuspec file in the ConsumerLibProj3 that contains $version$.
I'm generating Nuget Package for the ConsumerLibraryProj3 using following command
nuget pack ConsumerLibProj3.csproj -includereferencedprojects -verbosity detailed
The package gets generated successfully, but the version of the ClassLibProj1 and ClassLibProj2 dlls
in the package is not the latest. e.g. in the package ConsumerLibProj3.dll has version 1.0.0.2
whereas the ClassLibProj1.dll and ClassLibProj2.dll has version 1.0.0.1. The expectation is that all
the three dll's should have same version because the the version is coming from the
GlobalAssemblyInfo.cs file. The solution is using .NET Framework type project. Any help will be appreciated.
At last I was able to resolve this issue by forcing the nuget to use release configuration while packing. Surprisingly, I was building the solution with Release profile but still nuget was getting confused somehow. I used following command
nuget pack ConsumerLibProj3.csproj -includereferencedprojects -build -properties configuration=release -verbosity detailed
Thanks for the help.
I am working on referencing another set of .dlls in another project and have bundled it up via Nuget:
I get this error:
Severity Code Description Project File Line Suppression State
Error NU1701 Package 'MyPackageImTryingToInstall' was restored using '.NETFramework,Version=v4.6.1, .NETFramework,Version=v4.6.2, .NETFramework,Version=v4.7, .NETFramework,Version=v4.7.1, .NETFramework,Version=v4.7.2, .NETFramework,Version=v4.8' instead of the project target framework '.NETCoreApp,Version=v2.1'. This package may not be fully compatible with your project. 1
I understand the error, but how do I make .Nuget restore with .Net standard?
Just found that if I reference the Nuget in a .Net Framework 4.6.1 project - it works fine.
It has something to do with making a nuget from .net standard to .net standard.
I had to add lib folders for the target frameworks I wanted to add the nuget package to:
For the files section in the nuspec I needed to make a \netstandard2.0 folder and \461 folder
I have used visual studio 2019, I have added some NuGet packages but it's show error like..
Error Could not install package 'Microsoft.Build.Framework 14.3.0'. You are trying to install this package into a project that targets 'MonoAndroid,Version=v9.0', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.
Note: My Xamarin Binding library(Android) solution target version9.0.
please help me to resolve this issue.
Try by updating your Microsoft.Build.Framework package to the latest version (at the moment it is 16.0.461).
You can check it also here: https://www.nuget.org/packages/Microsoft.Build.Framework/
Once I copied the build task property section from my iOS csproj to my Android csproj.. I got a slightly different message. It asked me to add Microsoft.Build.Utilities.Core.
I then had to add the Microsoft.Win32.Registry 5 nuget then as it tried to install 4.3.0 which my Android project didn't like.
I encounter a stranger behavior with a Xamarin.Android project in Visual Studio on Windows.
I've created a new Android blank project, and I try ton install the NuGet package "AForge" (a mathematics library), but I get the following error message:
Package AForge 2.2.5 is not compatible with monoandroid81
(MonoAndroid,Version=v8.1).
I've already tried to re create several projects, after having relaunched Visual Studio and the computer, but the problem is still the same.
However, if I do the same thing on Mac, through Visual Studio for Mac, I don't encounter the same problem: the package is well installed.
In add, I can see in the package.config file, that the package il well related to monodroid81:
<?xml version="1.0" encoding="utf-8"?>
<packages>
<package id="AForge" version="2.2.5" targetFramework="monoandroid81" />
</packages>
Would you have any explanation about this issue?
Update: new issue
Hi #Leo Liu-MSFT, I come back to you as I encounter an new issue. The dll copy works fine locally, but I get an error on AppCenter:

So I tried your suggestion, but I get an error when I try to save the package:
a local file header is corrupted'
Would you have another suggestion?
Would you have any explanation about this issue?
You can get the official document here:
Description: With PackageReference, assemblies present at the root of
lib folder without a target framework specific sub-folder are ignored.
NuGet looks for a sub-folder matching the target framework moniker
(TFM) corresponding to the project’s target framework and installs the
matching assemblies into the project.
In this case, NuGet will consider installing this package to the .NET Framework, which is not compatible with monoandroid81. Then you will that error "Package AForge 2.2.5 is not compatible with monoandroid81".
To resolve this issue, the best way is contact the author of the AForge NuGet package to update this package, or you can also add reference dll file directly to your project.
Besides, if you still want to use nuget to manager this package, I would like provide you a workaround to resolve this issue:
Download this nuget package from nuget.org.
Copy the download package, rename it with .zip, like aforge.2.2.5 - Copy.nupkg.zip, then unzip it.
Open the package aforge.2.2.5.nupkg with NuGet Package Explorer(Get it from Microsoft store), add a new folder MonoAndroid81 under the lib node, add exists file AForge.dll and AForge.xml from the copy folder aforge.2.2.5 - Copy.nupkg.zip, save this nuget package.
Add this new create nuget package to the nuget local feed, then add this nuget package to the project. Do not forget delete the nuget package cache in the C:\Users\<UserName>\.nuget\packages\aforge before you add the package.
Hope this helps.

Nuget error install package Microsoft.NETCore.UniversalWindowsPlatform
but it is not, because the checkbox is checked by default in vs2017. I am running the creators update by the way and everything is up-to-date.
I have just started a new C# background IoT project and got this:
When manually installing the package in the package console I got this:
...
Successfully installed 'Microsoft.Net.Native.Compiler 1.6.0' to projectnamehere
Install failed. Rolling back...
Package 'Microsoft.NETCore.Jit.1.0.3' does not exist in project

ramework. For more information, contact the package author.
seems related to this https://connect.microsoft.com/VisualStudio/feedback/details/1617801/newly-created-universal-app-projects-dont-work
but I have no idea how to fix it.
I have also seen a website suggesting to remove the project.json file, which I did but did not resolve it.
I have also closed vs2017 and modified the installtion to verify that the creators update sdk was checked and installed.
I have lowered the target version in the project props, but that did not help either.
edit manual install the jit package did not work either:
Could not install package 'Microsoft.NETCore.Jit 1.1.1'. You are trying to install this package into a project that targets '.NETCore,Version=v5.0', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.
edit2 funny thing is that the solution explorer tells me that there is a project.json while there is none in windows explorer:
I verified the sdk installation by hitting the modify button of the vs2017 installation and tried to create a new project afterwards but got the exact same issue again.
Update: Microsoft updated the templates in their github (https://github.com/ms-iot/samples/commit/2e2aa34ab514b8c0725a53263898a412e0a1be1c) but didn't push it as an updated templates package to Visual Studio yet. Changed the answer accordingly.
Temporary fix:
replace in your .csproj file
<ItemGroup>
<!-- A reference to the entire .Net Framework and Windows SDK are automatically included -->
<None Include="project.json" />
</ItemGroup>
with
<PropertyGroup>
<RestoreProjectStyle>PackageReference</RestoreProjectStyle>
</PropertyGroup>
add the Microsoft.NETCore.UniversalWindowsPlatform package
Optional extra:
Add the Windows IoT Extension SDK via the references dialog
This issue has been fixed for Visual Studio 2017 in updated templates released here: https://marketplace.visualstudio.com/items?itemName=MicrosoftIoT.WindowsIoTCoreProjectTemplatesforVS15
