Cannot install NuGet package Microsoft.Bcl.Build 1.0.14

I am making a multi-platform app in VS 2013 (iOS, WinPhone and Android). I want to add into the iOS reference folder a Nuget Packages named Microsoft Http Clients Libraries and I cannot do it because I get the following error:

Could not install package 'Microsoft.Bcl.Build 1.0.14'. You are trying to install this package into a project that targets 'Xamarin.iOS,Version=v1.0', 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.

Can anybody help me with that?

I found the solution and put it here in case some one may face the same problem. Install "Microsoft.Bcl.Build.1.0.21" first for all your projects. Now you can install "PortableRest", all dependency that depends on Microsoft.Bcl.Build will be installed correctly.

In Visual Studio 2017 I encountered above error, and I solved the issue by installing Microsoft.Bcl.Build first on the Xamarin.Android, then installed Microsoft.Net.Http and System.Net.Http, but Xamarin.IOS and Xamarin.UWP there were no issues.

I was trying to install Microsoft.Net.Http in my Xamarin.Forms project when i faced this issue. Here is what you must try to get rid of this error:

1- Update Xamarin.Forms to latest version in each project of solution.

2- As my primary intention was to install Microsoft.Net.Http, and this package had dependencies on Microsoft.BCL and Microsoft.BCL.Build. I tried installing these packages (Microsoft.Bcl and Microsoft.Bcl.Build) individually and it worked for me. First install latest version of Microsoft.Bcl.Build 1.0.21 (If 1.0.14 did not install, try latest version). Then, install Microsoft.Bcl which should be installed successfully and this solution worked for me and I hope would work for you too. After installing these packages indivisually, I was able to install Microsoft.Net.Http successfully.

NOTE: While installing Packages (Microsoft.Bcl and Microsoft.Bcl.Build) into your projects, check which version you are installing. Try installing another version, if one does not work and let me know If problem does not solve.

Have a great day :)

I faced the same problem and apparently the Bcl.Build 1.0.14 can not be installed, but you probably you don't need that old version.

I faced this issue when I tried adding WindowsAzure.MobileService to the iOS Xamarin project. And it failed, because the minimal supported Bcl.Build is required to be 1.0.14, but if you have a newer version, which installs quite fine, you will be able to add other packages that depend on it.

So 1. Install Microsoft.Bcl.Build package separately (the latest) 2. Install your package that depends on it.

Microsoft.Bcl.Build 1.0.14 can be installed into Xamarin.iOS projects.

It may fail if:

  1. Your NuGet Package manager is not up to date.
  2. You do not have the Xamarin Portable Class Library profiles for Xamarin.iOS installed.

If you have the latest Xamarin version installed it is probably the NuGet Package Manager not being up to date. You can update it from Tools - Extensions and Updates - Updates - Visual Studio Gallery.
