问题描述
我在 Visual Studio 2019 中有一个包含许多 C# 项目的解决方案.我需要将所有项目从 .NET Framework 4.5.1 重新定位到 4.8.是否可以立即更改目标，还是必须对每个目标单独进行更改?
I have a solution in Visual Studio 2019 with many C # projects. I need to retarget all of the projects from the .NET Framework 4.5.1 to 4.8. Is it possible to change target at once or do I have to do it separately with every single one of them?
PS:我尝试过TargetFrameworkMigrator"，但它不适用于 (VS2019)/.net 4.8.
PS: I tried 'TargetFrameworkMigrator', but it doesn't work with (VS2019) / .net 4.8.
感谢您的帮助.
推荐答案
不幸的是，VS 没有为 .NET 框架提供简单的方法，并且每个项目文件都有自己的设置.所以最简单的方法可能是在VS或任何你喜欢的文本编辑器中的目录上编辑->查找和替换->在文件中替换".
VS unfortunately doesn't provide an easy way for .NET framework, and every project file has it's own setting. So the easiest way is probably a "Edit -> Find and Replace- > Replace in Files" on the directory in VS or any text editor you like.
对于框架项目，在每个 .csproj 中你需要 (来自 v4.5.1</TargetFrameworkVersion>)，如果您有任何 packages.config，则有 targetFramework="net48"(来自 targetFramework="net451").您需要在更改后重新加载解决方案以让 VS 看到它们.
For Framework projects, in every .csproj you want <TargetFrameworkVersion>v4.8</TargetFrameworkVersion> (from <TargetFrameworkVersion>v4.5.1</TargetFrameworkVersion>), if you have any packages.config, there is targetFramework="net48" (from targetFramework="net451"). You will need to reload the solution after changing for VS to see them.
