Silverlight 4: Resolving Microsoft.Silverlight.CSharp.targets was not found?
提问by Brandon
I've been upgrading some Silverlight 3 apps to Silverlight 4 in Visual Studio 2010. My Silverlight 3 apps open fine in Visual Studio, but SL4 apps don't, with the following error:
我一直在 Visual Studio 2010 中将一些 Silverlight 3 应用程序升级到 Silverlight 4。我的 Silverlight 3 应用程序在 Visual Studio 中打开正常，但 SL4 应用程序没有，出现以下错误：
C:\Path\To\MyProject.csproj : error : Unable to read the project file 'XNTVOD.AdminClient.csproj'.
C:\Path\To\MyProject.csproj(593,3): The imported project "C:\Program Files (x86)\MSBuild\Microsoft\Silverlight\v4.0\Microsoft.Silverlight.CSharp.targets" was not found. Confirm that the path in the <Import> declaration is correct, and that the file exists on disk.

C:\Path\To\MyProject.csproj(593,3): The imported project "C:\Program Files (x86)\MSBuild\Microsoft\Silverlight\v4.0\Microsoft.Silverlight.CSharp.targets" was not found. Confirm that the path in the <Import> declaration is correct, and that the file exists on disk.
I had a problem with older VS Silverlight components and recently uninstalled most of the SL components, and right now in Add/Remove programs I have:
我在使用较旧的 VS Silverlight 组件时遇到了问题，最近卸载了大部分 SL 组件，现在在添加/删除程序中我有：
- Microsoft Silverlight
- Microsoft Silverlight 3 SDK
- Microsoft Silverlight 4 Toolkit April 2010
- 微软银光
- 微软 Silverlight 3 SDK
- Microsoft Silverlight 4 工具包 2010 年 4 月
The <import>declaration looks like this for the SL4 project:
<import>SL4 项目的声明如下所示：
<Import Project="$(MSBuildExtensionsPath32)\Microsoft\Silverlight\$(SilverlightVersion)\Microsoft.Silverlight.CSharp.targets" />
<Import Project="$(MSBuildExtensionsPath32)\Microsoft\Silverlight\$(SilverlightVersion)\Microsoft.Silverlight.CSharp.targets" />
That folder, C:\Program Files (x86)\MSBuild\Microsoft\Silverlight\v4.0only has two files in it:
该文件夹中C:\Program Files (x86)\MSBuild\Microsoft\Silverlight\v4.0只有两个文件：
Microsoft.Ria.Client.targets
Microsoft.Ria.Client.targets
Microsoft.Ria.Client.VisualStudio.targets
Microsoft.Ria.Client.VisualStudio.targets
What Silverlight development component am I missing in particular? I see a bunch of different options, from Silverlight 4 SDK Beta to VS Tools for Silverlight 4 and a bunch of others. I don't want to install stuff that will get me right back to the situation I had before this one with outdated components.
我特别缺少什么 Silverlight 开发组件？我看到了许多不同的选项，从 Silverlight 4 SDK Beta 到 Silverlight 4 的 VS Tools 以及其他一些选项。我不想安装那些会让我回到我之前使用过时组件的情况的东西。

The file that's missing ships in the Silverlight 4 SDK. You can either install just the Silverlight 4 SDK, or re-install the entire Silverlight 4 Tools for VS2010package (which will re-install the developer runtime, SDK, a hotfix for VS2010, the Silverlight 4 Tools package, and WCF RIA Services).
Silverlight 4 SDK 中提供了缺少的文件。您可以只安装Silverlight 4 SDK，也可以重新安装整个Silverlight 4 Tools for VS2010包（这将重新安装开发人员运行时、SDK、VS2010 的修补程序、Silverlight 4 工具包和 WCF RIA 服务） .

You may get this with Silverlight version 4 projects when trying to open in version 5 if version 4 bits are not on that machine. What has worked for me (after several hours of trying everything) is to edit the csproj file and change the silverlight target version
如果版本 4 位不在该计算机上，则尝试在版本 5 中打开时，您可能会在 Silverlight 版本 4 项目中获得此信息。对我有用的（经过几个小时的尝试）是编辑 csproj 文件并更改 Silverlight 目标版本
<TargetFrameworkVersion>v4.0</TargetFrameworkVersion>
From 4 to 5
从 4 到 5

This worked well for me...also had to install Silverlight 4 Developer runtime
这对我来说效果很好……还必须安装Silverlight 4 Developer 运行时

Afer many tries, what worked for me was: 1. go to add or remove programms 2. remove all silverlight versions installed (4, 5 or even if version is not specified remove it too!) 3. install Silverlight 4 SDK 4. install Silverlight 5 for developers Finally opened the project in VS 2010 SP1
经过多次尝试，对我有用的是： 1. 去添加或删除程序 2. 删除所有安装的 Silverlight 版本（4、5 或即使未指定版本也删除它！） 3. 安装 Silverlight 4 SDK 4. 安装Silverlight 5 for Developers 终于在VS 2010 SP1中开启了项目

A previously working installation can break when you install a new version of TFS on the server (or whatever it was that messed with my MSBuild).
当您在服务器上安装新版本的 TFS（或任何与我的 MSBuild 混淆的东西）时，以前工作的安装可能会中断。
My 'targets' files had disappeared from C:\Program Files (x86)\MSBuild\Microsoft\Silverlight\v5.0on Server 2012 and reinstalling the tools.
我的“目标”文件已从C:\Program Files (x86)\MSBuild\Microsoft\Silverlight\v5.0Server 2012 上消失并重新安装了这些工具。
I believe it may be possible to just copy the targets files from another machine but not 100% sure.
我相信可以只从另一台机器复制目标文件，但不能 100% 确定。
