. Net cannot open the. sln or. vcproj File

. Net cannot open the. sln or. vcproj file. The main cause of this problem is that the version is lower

The version corresponding to the file should never be scared. Instead, install an IDE with a higher version.

The solution is simple: Open the corresponding. sln or. vcproj in any text editor such as UE or notepad.

It is best to open the. vcproj file, because .. SLN is generated by it, find the following mark

Projecttype = "Visual C ++"
Version = "8.xx"

Change

Projecttype = "Visual C ++"
Version = "7.10"

Save. Double-click the file to open the project. (However, we have to look at Rp if we can compile the compiler.

The version does not have some libraries of the higher version... Ms too)
