“GalaSoft”MvvmLight不能在便携式项目中找到 [英] 'GalaSoft' MvvmLight could not be found in Portable project

问题描述

我克隆了一个解决方案，它包含基于GalaSoft MvvmLight图书馆多个项目，也有两个项目便携。我已经安装了所有需要的NuGet包和引用，但我不能够建立这些便携式的项目和它的，因为所有其他项目中引用它首先建立这些便携式项目所需。
结果我得到了每个文件GalaSoft本（下同）错误使用。它是一种便携式类库项目。

I have cloned a solution, it contains multiple projects based on GalaSoft MvvmLight library, also it has two Portable Projects. I have installed all required nuget packages and references but I am not able to build these portable projects and its required to build these portable projects first because all other projects reference it.

推荐答案

所以，你的问题是，MVVM光有没有包针对您的PCL的个人资料。

So your problem is that mvvm light has no package targeting your PCL profile.

当您使用的NuGet安装MvvmLightLibs下载包你可以看到，包中包含只有一个PCL配置文件中的组件。 MVVM光支持便携式net45 + WP8 + wpa81 + netcore45 + monoandroid1 + xamarin.ios10 。但是，你的目标PCL .NETPortable，版本= V4.5，外形= Profile78 。
如果你wan't你的项目是兼容MVVM照亮你必须删除 SL5 目标。

When you download the package using nuget install MvvmLightLibs you can see that the package contains the assemblies for only one PCL profile. Mvvm light supports portable-net45+wp8+wpa81+netcore45+monoandroid1+xamarin.ios10. But your PCL targets .NETPortable,Version=v4.5,Profile=Profile78. If you wan’t your project to be compatible with mvvm light you have to remove the sl5 target.
