Upgrading sln to Open With Visual Studio 2022 Community

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, @njsokalski

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:
147707-image.png

Visual Studio 2022:
147708-image.png

"# 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:
147733-image.png
Double click the sln file, it will open in VS2020.

You can refer to Solution (.sln) file.

Sincerely,
Peng

Thanks! That seems to work great!

I do also have one other question (I am asking it here because it is very closely related, I am guessing most people that want to know one want to know the other as well). Like most people, there are many customization I have made in the settings & options, and I would obviously like to use most of the same settings in Visual Studio 2022 as I did in Visual Studio 2019. As we know, these settings can be exported as .vssettings. Is it safe/valid/appropriate to import a .vssettings created by Visual Studio 2019 into Visual Studio 2022?

I tried this and it didn't work at first. I had to review the settings for 'Default programs' and change the setting for .sln files to the Visual Studio Version Selector.
