I have had an issue over the past few weeks with nuget package manager. Basically everytime I try to install a package it gives me and error like this:
Install failed. Rolling back...
Install-Package:
Could not install package 'WPtoolkit 4.2013.06.11'. You are trying to install this package into a project that targets 'WindowsPhone,Version=v8.0', but the package does not
contain any assembly references that are compatible with that framework. For more information, contact the package author.
I get a similar issue with every package I try to install even though the packages clearly state they support wp8.
This issue is getting very frustrating and is making the nuget package manager feature all but useless for me.
Any help would be greatly appreciated.

I have a blazor server side app that is working without problem. (Net Core 3.1). I tried to install Blazorise according the quick start page in https://blazorise.com/docs/start. As my server has no internet access I have downloaded the packages "Blazorise.Bootstrap 0.7.2" and "Blazorise.Icons.FontAwesome 0.9.2.5".
I can install the "Blazorise.Icons.FontAwesome" without Error. But if I try to install "Blazorise.Bootstrap" I get the Error
"NU1101: Unable to find package Microsoft.AspNetCore.Blazor. No packages exist with this id in source(s): Microsoft Visual Studio Offline Packages, Package source"
I cannot find any package like "Microsoft.AspNetCore.Blazor". What should I do now?
Update1:
I have found a package like "Microsoft.AspNetCore.Blazor.Templates 3.1.0-preview4.19579.2" but if I try to install I get Error
"Package 'Microsoft.AspNetCore.Blazor.Templates 3.1.0-preview4.19579.2' has a package type 'Template' that is not supported by project 'WebApplication7'"
I had some problmes at the beginning with updateing NetCore3.1 to Net6.0 But at the end I fixed them. So I could install Blazorise's last version without problem.
Thanks for the comments, suggesting that.
I am trying to start my first Xamarin project and I got some issue while trying to install the MySqlEntity NuGet package.
Severity Code Description Project File Line Suppression State
Error NU1202 Package MySql.Data.Entity 6.10.8 is not compatible with monoandroid81 (MonoAndroid,Version=v8.1). Package MySql.Data.Entity 6.10.8 supports: net452 (.NETFramework,Version=v4.5.2) Refo_T3.Android C:\Users\evyat\source\repos\Refo_T3\Refo_T3\Refo_T3.Android\Refo_T3.Android.csproj 1
I tried this solution: Xamarin.Android: Package XX is not compatible with monoandroid81 (MonoAndroid,Version=v8.1)
and I still end up with errors.
It's my first application on Xamarin platform, I used to code in .NET but I decided to test my luck with Xamarin.
I couldn't find any more useful information online and I need your better experience.
Thank You :)
As written on the nuget packages page, the package is only available for .net framework >= 4.5.2
So you can't install it for Xamarin Android project only classic desktop .Net Framework applications.
I am getting the following error when i try to build an AspNetCore Web Application targeting netcoreapp2.2.
Error MSB4057 The target "ResolveTagHelperRazorGenerateInputs" does not exist in the project. C:\Program Files\dotnet\sdk\2.2.103\Sdks\Microsoft.NET.Sdk.Razor\build\netstandard2.0\Sdk.Razor.CurrentVersion.targets
I have tried the following:
clear cache on vs according to this post
update vs2017 to 15.9.5
reinstall net core sdks
reinstall vs
Nothing helped. I first got the error during an upgrade from core 2.1 to core 2.2 on a different project, and it's possible that by mistake edited the
Sdk.Razor.CurrentVersion.targets file. From that moment on, i keep getting this error on any project that targets core 2.2 (even new ones).
Does anyone encountered this problem or have any clues about solving it?
Thanks
After long battles it figured out to be a problem with VS NuGet Package Manager.
All I had to do was:
VS > Tools > Options > NuGet Package Manager > Clear All NuGet Cache(s).
The Following Link was my solution. I also struggled to get this fixed.
Just copy the files from the NetStandard2.0 folder from GitHub then replace it with you Directory from the same location.
Hopefully this helps someone.!

Here is the GitHub Link

I encountered the same issue during the Azure build pipeline process, and clearing the NuGet package cache resolved the issue.
Solution:
I used a dotnet tasks with "custom" to issue the following command before NuGet package restore task:
command:
dotnet nuget locals global-packages -c
Screenshot shows the build pipeline task
For me the solution was as follows:
In Visual Studio
Right click on each project and click "Unload Project"
Right click on each project and click "Reload Project"
This issue has been reported on GitHub here -
https://github.com/TorbenK/TK.CustomMap/issues/325
Has anyone else has struggled with this? I was stoked to find this nuget package because it does exactly what I'm looking for but it needs Places and some other GooglePlayServices installed and I can't install them because of this conflict.
I'm also not sure if uninstalling TK.CustomMap and then installing the Play Services would even help because the person who reported the issue on GitHub said-
I converted my app to .net 2.0 and had to use the newest Google play services
60.1142.1 for AdMob to work. It wouldn't install until I uninstalled TK.CustomMap, and now TK.CustomMap won't reinstall because it only want to use GooglePlayServices 42.1021.1
Severity Code Description Project File Line Suppression State
Error NU1107 Version conflict detected for Xamarin.GooglePlayServices.Tasks. Reference the package directly from the project to resolve this issue.
HunterTracker.Android -> Xamarin.GooglePlayServices.Base 60.1142.1 -> Xamarin.GooglePlayServices.Tasks (= 60.1142.1)
HunterTracker.Android -> HunterTracker -> TK.CustomMap 2.0.1 -> Xamarin.GooglePlayServices.Location 42.1021.1 -> Xamarin.GooglePlayServices.Tasks (= 42.1021.1).
That's pretty much the exact error I'm getting trying to install the other packages. There's no resolution on github.
Anybody found a work around? Or does anyone know how to "Reference the package directly from the project"?
Thanks to SushiHangover's comments above pointing me in the right direction I was able to discover what I needed to do here. I had an error updating the nuget packages of TK.CustomMap at first because v26 Xamarin.Android.Support.Vector.Drawable was targeting MonoAndroid8.0 and the update to v27 must target MonoAndroid8.1 So it took quite a bit just to be able to update the nuget packages in order to get the assemblies with later versions so I could use TK.CustomMap in my solution. But I was eventually able to get there. Here were the steps I followed (as best I can remember). I am unable to compile ios right now because I don't have a MAC so that fix will have to come later. This fix is for the shared project and Android project only
Download the TK.CustomMap-master from github
Extract it and delete the Sample project completely (I also deleted the UWP project as I'm not really interested in that at this time)
Opened and built then closed. Deleted packages folder, vs folder, bin and obj from Android and Shared Project (this step is probably not necessary but I did it so...)
In the packages.config in Android changed all targets from monoandroid80 to monoandroid81 save file
In the TK.CustomMap.Android.csproj for every v26.0.1 of any Xamarin.Android.Support or other Xamarin.Android util package changed 26.0.1\lib\MonoAndroid80 to 27.0.2.1\lib\MonoAndroid81 - save file
In the nuget folder in TK.CustomMap.nuspec changed the target framework in this section
<group targetFramework="lib\MonoAndroid7.0">
<dependency id="Xamarin.GooglePlayServices.Location" version="42.1021.1" />
<dependency id="Xamarin.GooglePlayServices.Places" version="42.1021.1" />
<dependency id="Xamarin.Android.Maps.Utils" version="0.5.0" />
<dependency id="Xamarin.Forms" version="2.5.0.91635" />
<dependency id="Newtonsoft.Json" version="10.0.3" />
</group>
to
<group targetFramework="lib\MonoAndroid">
so it could target any version
Opened and updated all nuget packages using package manager (not console). Built debug and release builds
At this point opened solution I had tried to implement TK.CustomMap in previously to attempt the fix. Remember the original issues was that the latest frameworks could not be used and 42.1021.1 frameworks were unable to locate com.google.gms.location and com.google.gms.places.ui files so they had to be updated or no TK.CustomMap
In the problem solution uninstalled TK.CustomMap from all projects
In the problem solution Android project added reference to all the dlls in the release folder of the Android bin file from TK.CustomMap project.
Installed updates for all Xamarin.Android frameworks in problem solution through Package Manager (not console)
Installed updates of all other nuget packages for all projects using Package Manager (not console)
Installed TK.CustomMap to Shared project using Package Manager (not console)
Added the References to the android project a second time. May or may not have helped.
Installed TK.CustomMap Nuget Package using Package Manager (not console)
Built and ran on Live Player successfully!!
Thanks to Sushi Hangover for the advice. I haven't seen any comprehensive tutorials anywhere on how to accomplish this so I figured I would post my own answer in case anyone else was looking. Definitely if you are new to VS all this stuff is no walk in the park in the beginning.
Thanks to #Travis Fleenor. This is my solution. I change a bit your sequence in order to work on mine.
1. Make sure the original proyect from github (https://github.com/TorbenK/TK.CustomMap) works and you can run it.
2. Update the nugets where you get the conflict. In my case I got conflicted in googleplay library version. I updated it in the original proyect and then assure it could run it.
3. Compile entire solution in release mode. Then, copied the generated dll from bin/release and pasted them in a folder in my desktop.
4. I referenced those dll to shared proyect and android proyect. I only used nuget package manager to install some missing packages needed for the tk.custom. Notice that you only will reference some dll that the proyect accept. For the mayority Visual will prompt ' dll already referenced' something.
5. first reference your shared proyect, later your android one. That's all. make sure the you ca recompile solution.
Hope this helps
I am trying to run the MvvmCross TipCalc sample. Using NuGet on TipCalc.UI.Droid to resolve references works OK. I then try to do same on TipCalc.Core and get:
Adding 'MvvmCross.PortableSupport 3.0.13' to TipCalc.Core.
Could not install package 'MvvmCross.PortableSupport 3.0.13'. You are trying
to install this package into a project that targets 'portable-win+net40+sl40+wp',
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.
Shouldn't the project just be ready to go for NuGet and it should "just work"? I am newbie to NuGet and MvvmCross. I am on Win7, VS.NET 2012, NuGet 2.7.40911.225, and latest MvvmCross-Tutorials from GitHub.
The problem will probably be in 'net40' and 'wp' platforms you've included - for PCL reasons we need a minimum of 'net45' and wp75' used - see the chart in http://msdn.microsoft.com/en-us/library/gg597391.aspx for the fact that 'net40' doesn't currently support Mvvm Types (e.g. INotifyPropertyChanged).
If it helps, my current development setup here has remained unchanged since March - it's still http://slodge.blogspot.co.uk/2013/04/my-current-pcl-setup-in-visual-studio.html
Shouldn't the project just be ready to go for NuGet and it should "just work"?
The process towards getting all the tooling for PCLs, nuget, VS, XS, etc working across all the platforms has been slow, hard work.... it is happening and it will one day 'just work' but it continues to take time and lots of work from lots of people.
There are still open workitems within nuget and within Xamarin - e.g. http://nuget.codeplex.com/workitem/2926 - which people are working on; some of the MS legal hurdles have recently been cleared (http://blogs.msdn.com/b/dotnet/archive/2013/10/14/portable-class-library-pcl-now-available-on-all-platforms.aspx); and technically things change on the Xamarin side with almost every Alpha release. But it is hard to get definitive answers on when things will be 100% ready and will "just work".
The good news is that:
with the 2 XML files from http://slodge.blogspot.co.uk/2013/04/my-current-pcl-setup-in-visual-studio.html I and plenty of others have been happily using PCLs and nuget for the last 6 months or so.
progress is still moving forwards
