Open Visual Studio Solution file only in VS 2019

Question

I was using .NET Core API project with 2.2 Framework in VS 2017. Now we have migrated all the .NET Core API Projects to 3.0 Framework.I have both VS 2017 and 2019 installed in my machine. When we click on ".sln" file it gets openend in VS 2017. But i want the .sln file to be openend in VS 2019. Please let me know the changes required to achieve this.

Thanks

Answer 1

For one, you can delete the solution file and create a new one dotnet new sln.

Assuming you have .NET Core 3.0 sdk installed and active (in case of globa.json being present), it should create you an *.sln file for VS 2019.

Alternatively edit your sln and change the first few lines to

Microsoft Visual Studio Solution File, Format Version 12.00
# Visual Studio Version 16
VisualStudioVersion = 16.0.29512.175
MinimumVisualStudioVersion = 10.0.40219.1

thats the sln header VS 2019.4 (16.4) creates on new solutions

Answer 2

1. Right-click on the .sln file
2. From the popup menu click on "Open with" and in the submenu click on "Choose another app"

3. In the splash window select "Microsoft Visual Studio Version Selector", don't forget to tick the "Always use this app to open .sln files" checkbox, and click "OK".

4. If prompted to save changes to the "devenv.sln" file, save changes.

In this way, a double click on a .sln should open it with the version of Visual Studio that was used to create it.
