Upgrading sln to Open With Visual Studio 2022 Community

Question

I recently installed Visual Studio 2022 Community. Most of my Solutions & Projects were created with Visual Studio 2019, and I would like to upgrade them for use with Visual Studio 2022. I can open them in Visual Studio 2022 manually, but I would like to upgrade them so that the Version Selector will choose Visual Studio 2022, and I would like to make any appropriate changes to the sln & csproj files. Is there any tool or standard process for doing this?

Hi, @Nathan Sokalski

Welcome to Microsoft Q&A!

You can open the sln file of the project, for example, using Visual Studio Code.
This is a partial screenshot of two sln files, the upper one was created by Visual Studio 2019, and the lower one was created by Visual Studio 2022.

Visual Studio 2019:

Visual Studio 2022:

"# Visual Studio Version 16"
The major version of Visual Studio that (most recently) saved this solution file. This information controls the version number in the solution icon.
VisualStudioVersion = 16.0.28701.123
The full version of Visual Studio that (most recently) saved the solution file. If the solution file is saved by a newer version of Visual Studio that has the same major version, this value is not updated so as to lessen churn in the file.

You can modify these two version numbers.
As an example, I modified the version number of the sln file created by VS2019:

Double click the sln file, it will open in VS2020.

You can refer to Solution (.sln) file.

Sincerely,
Peng
