[英]Change the Target Framework for all my projects in a Visual Studio Solution
I need to change the target framework for all projects.我需要更改所有项目的目标框架。 I have many solutions with hundreds of projects.我有数百个项目的许多解决方案。
Anything new here or do I have to change every single project?这里有什么新东西还是我必须改变每个项目?
刚刚发布了Target Framework Migrator ,Visual Studio Extension,用于一次更改多个 .Net 项目 Target Framework
You can do that using Scott Dorman's Visual Studio macro available on CodeProject:您可以使用 CodeProject 上提供的 Scott Dorman 的 Visual Studio 宏来做到这一点:
Visual Studio 2010 and Target Framework Version Visual Studio 2010 和目标框架版本
Below is the code, download it to your <UserProfile>\\Documents\\Visual Studio 2010\\Projects\\VSMacros80\\MyMacros
folder, open the Visual Studio Macro IDE (Alt-F11) and add it as an existing item to the “MyMacros” project:下面是代码,将其下载到<UserProfile>\\Documents\\Visual Studio 2010\\Projects\\VSMacros80\\MyMacros
文件夹,打开 Visual Studio Macro IDE (Alt-F11) 并将其作为现有项目添加到“MyMacros”项目:

A PowerShell script that I used to do mine.我曾经做过的一个 PowerShell 脚本。 Admittedly bruce force-ish.不可否认,布鲁斯力-ish。
Get-ChildItem . -Recurse -Filter *.*proj |ForEach {
$content = Get-Content $_.FullName
$content |ForEach {
$_.Replace("<TargetFrameworkVersion>v4.0</TargetFrameworkVersion>", "<TargetFrameworkVersion>v4.5</TargetFrameworkVersion>")
} |Set-Content $_.FullName
}
There's always the simple.总是有简单的。 A decent text editor such as notepad++ will include a find/replace in files function.一个不错的文本编辑器,例如记事本++,将在文件中包含查找/替换功能。 Just search for the current version string in your csproj/vbproj files:只需在您的 csproj/vbproj 文件中搜索当前版本字符串:
<TargetFrameworkVersion>v3.5</TargetFrameworkVersion>
and replace with the new version并替换为新版本
<TargetFrameworkVersion>v4.5</TargetFrameworkVersion>
Good idea to check out first though...不过,先检查一下是个好主意......
来自 bash:
$find . -name "*.csproj" -exec sed -b -i "s,<TargetFrameworkVersion>[^<]*</TargetFrameworkVersion>,<TargetFrameworkVersion>v4.6.1</TargetFrameworkVersion>," {} \;
I think by far the easiest way to do this is using a search and replace tool.我认为到目前为止最简单的方法是使用搜索和替换工具。 It is an advantage if it supports regex.如果它支持正则表达式,这是一个优势。
There must be quite a few out there - the first one I tested worked for me, though: http://www.ecobyte.com/replacetext/那里肯定有很多 - 不过我测试的第一个对我有用: http : //www.ecobyte.com/replacetext/
There is a note saying it has some issues on Win7, but I didn't experience that.有一个说明说它在Win7上有一些问题,但我没有遇到过。
Step by step instructions in that tool:该工具中的分步说明:
<TargetFrameworkVersion>.*</TargetFrameworkVersion>
)在搜索文本框中输入您的正则表达式(例如<TargetFrameworkVersion>.*</TargetFrameworkVersion>
)<TargetFrameworkVersion>4.0</TargetFrameworkVersion>
)输入替换文本(例如<TargetFrameworkVersion>4.0</TargetFrameworkVersion>
)Now If for some reason you need to do this in code, I would probably be able to do that as well (it's how I found this question).现在,如果出于某种原因您需要在代码中执行此操作,我可能也可以执行此操作(这就是我发现此问题的方式)。 In that case, please request it in a comment.在这种情况下,请在评论中提出要求。

Conditional regexes are giving me a headache. 条件正则表达式让我头疼。 So here is a coded solution for search/replace (I'm avoiding EnvDTE as long as possible).所以这是一个用于搜索/替换的编码解决方案(我尽可能避免使用 EnvDTE)。
Order does not seem to matter for the project file entries:项目文件条目的顺序似乎无关紧要:
Try something along those lines:沿着这些方向尝试一些事情:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Text.RegularExpressions;
namespace TextReplaceDemo
{
class Program
{
static void Main(string[] args)
{
try
{
ReplaceTargetFrameworkVersion("v4.0", "c:/projekt/2005", "*.csproj");
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
}
/// <summary>
/// Inserts the denoted targetFramework into all occurrences of TargetFrameworkVersion.
/// If the TargetFrameworkVersion is not present in the file, the method searches for the
/// OutputType tag, which should be present, and inserts the TargetFrameworkVersion before that.
/// </summary>
/// <param name="targetFramework">New target framework (e.g. "v4.0")</param>
/// <param name="rootDirectory">Root directory for the file search (e.g. "c:\Projects\2005")</param>
/// <param name="fileSearchPattern">Pattern to find the project files (e.g. "*.csproj).
/// Will get all files for empty parameter.</param>
public static void ReplaceTargetFrameworkVersion(string targetFramework, string rootDirectory, string fileSearchPattern)
{
if (string.IsNullOrEmpty(targetFramework)) throw new ArgumentNullException("targetFramework");
if (string.IsNullOrEmpty(rootDirectory)) throw new ArgumentNullException("rootDirectory");
if (string.IsNullOrEmpty(fileSearchPattern)) fileSearchPattern = "*.*";
string regexPattern = "<TargetFrameworkVersion>.*</TargetFrameworkVersion>";
string insertText = string.Format("<TargetFrameworkVersion>{0}</TargetFrameworkVersion>", targetFramework);
string alternativeMarker = "<OutputType>";
// get all files
List<FileInfo> files = GetAllFiles(rootDirectory, fileSearchPattern);
// iterate over found files
foreach (var file in files)
{
string fileContent = File.ReadAllText(file.FullName);
Match match = Regex.Match(fileContent, regexPattern);
string newfileContent = null;
if (match.Success)
{
// replace <TargetFrameworkVersion>
newfileContent = fileContent.Replace(match.Value, insertText);
}
else if (fileContent.Contains(alternativeMarker))
{
// create <TargetFrameworkVersion>
newfileContent = fileContent.Replace(alternativeMarker,
insertText + Environment.NewLine + " " + alternativeMarker);
}
// overwrite file
if (newfileContent != null)
File.WriteAllText(file.FullName, newfileContent);
}
}
/// <summary>
/// Recursive function to find all files in a directory by a searchPattern
/// </summary>
/// <param name="path">Path to the root directory</param>
/// <param name="searchPattern">Pattern for the file search, e.g. "*.txt"</param>
public static List<FileInfo> GetAllFiles(string path, string searchPattern)
{
List<FileInfo> files = new List<FileInfo>();
DirectoryInfo dir = new DirectoryInfo(path);
if (dir.Exists)
{
// get all files in directory
files.AddRange(dir.GetFiles(searchPattern));
// get all files of subdirectories
foreach (var subDir in dir.GetDirectories())
{
files.AddRange(GetAllFiles(subDir.FullName, searchPattern));
}
}
return files;
}
}
}
You can use a macro to do this, or remember that the VS project files are text files, which means a simple global search and replace can achieve the same, and is a more general technique for making the same change to lots of project files.您可以使用宏来执行此操作,或者记住 VS 项目文件是文本文件,这意味着简单的全局搜索和替换可以实现相同的效果,并且是对大量项目文件进行相同更改的更通用技术。
First back up an existing project file, then make the change you want (eg, change the target framework).首先备份现有的项目文件,然后进行所需的更改(例如,更改目标框架)。 Use WinDiff or WinMerge to compare the new project file with the back up.使用 WinDiff 或WinMerge将新项目文件与备份文件进行比较。 This will tell you the change you need to make.这将告诉您需要进行的更改。 Then use the Visual Studio IDE's Find and Replace in Files function to make the change to all your project files.然后使用 Visual Studio IDE 的“在文件中查找和替换”功能对所有项目文件进行更改。
An alternative with no external tools (and the ability to change other settings, eg ToolsVersion):没有外部工具的替代方案(以及更改其他设置的能力,例如 ToolsVersion):
<ItemGroup>
<None Include="**\*.csproj" />
</ItemGroup>
This can easily be extended for other project types.这可以很容易地扩展到其他项目类型。
