VS2010和VS2012的两个C＃项目文件在同一目录中

Question

I'm writing a C# project which I want to compile both under VS2010 and VS2012. I want to have two different .csproj files for that, even though VS2010-project can be directly included in VS2012-solution. I want two different project files because of different target .NET-versions.

Additionally, I want both projects to be named the same within different solutions for VS2010 and VS2012. The both should share the same .cs -files and, possibly, some resources.

Easy task? Strange thing, but I don't know, how to do that properly.

• First approach, doesn't work: name project files as MyProject10.csproj and MyProject12.csproj , leave both in the MyProject folder. But in this case they are displayed in solution as MyProject10 and MyProject12 , not simply MyProject . If I rename one to MyProject in solution explorer, it automatically renames the corresponding project file.

• Second approach, works, but has drawbacks. Move project files into different subdirectories, named VS10 and VS12 , manually change include paths in .csproj -files, adding ..\\ as a prefix. In this case I see strange shortcut-like arrows under the icons in solution explorer.

The only bad thing for the second approach is that when I add new files in the project using solution explorer, this file is placed in the VS10 subdirectory, not in the root project directory. But it seems like project directories for .csproj -files are the directories containing the file by design, and I use the dark side of the force which I really don't want to do.

Any better ideas?

Worth giving a try is changing the name of the output assembly in both projects to one and the same. The project files are still going to be different, but the output assembly will be with same name. Also be carefull where is the output directory. I think this way you can sovle your problem.
