Because of the needs of different projects, Visual Studio version is installed on your computer. as we all know, a project or solution created in a Visual Studio version cannot be opened directly using Visual Studio of another version, but must be converted. after vs2010 is installed, the previous vs2005 project will be forcibly converted to the vs2010 project, causing trouble for a computer without vs2010 to be unable to open a later project.
When a project or solution created by Visual Studio of a later version is opened, the Visual Studio conversion wizard is automatically opened ", during the conversion process, you can back up the old project or solution (by default, it is backed up to the/backup folder under the solution folder). This method is simple because the wizard mode is enabled, not detailed.
Another direct method isModify the version information in the soultion file and project fileThis method can be upgraded from a lower version to a later version, or from a later version to a later version.
Step 1. Let's take a look at this image first.
This is the visual studio2005 (left) and visual studio2010 (right) solutions and engineering project files. the content is the same. You can see that the visual studio2010 (right) solution file is 1kb larger than visual studio2005 (left.
Step 2. Use the software ultracompare to open visual studio2005 (left) and visual studio2010 (right) solutions for text comparison:
The differences between the two solutions are obvious. Modify the solution file: change version 11.00 in the red box to 9.00; change Visual Studio 2010 to Visual Studio 2005, for example:
List all Visual Studio versions and their corresponding format versions as follows:
