Question

User-973886032 posted

hi guys

I have vs 2017 installed and wanted to run vs 2019 side by side, however when i upgraded the installer, there is no option to install 2019, it just says upgrade and shows me about 500mb of space required

in times past, I like to believe i ran 2 versions together

Also if i do upgrade, would I still be able to run backward compatibility with my version 2.0 and 2.2 ?

please advise

Ehi

Hi,

You mean the installer just updated itself ? My understanding is that you need to run explicitely the installer for the VS edition you want to "register" it into your current installer.

Edit: VS 2017 was installed, I ran the VS 2019 installer which is now v 2.1.3125.514 and I do see both VS 2017 and 2019 in it.

Not 100% sure but if I remember on another machine I installed VS 2019 Community first and had to run explicitely the VS 2017 Community installer as well to finally see both version as well in the installer.

Hi afrika,

As far as I known, you could  install multiple versions of Visual studio side by side.But you should install the lower versions first.In your situation,I think you couldn't use update,it will just update your vs2017 to vs2019. If you wan to run two versions together,I think you should install vs2019 alone. 

Then If you use Visual Studio 2019 to open a solution that was created in Visual Studio 2017 with Service Pack 1 (SP1), you can later open and modify the solution again in the older version as long as you haven't implemented any features that are specific to Visual Studio 2019.

Else,if you just upgrade I think you could still be able run .net framework 2.0 and 2.2, you could choose either of them for  web application as long as you provide the Sdk.

Here is the link,I hope it could help you.

sorry this is a bit late, I have been in and out

I finally got it to work. Initially the installer was only giving me the option of VS 2017, But it suddenly gave me the option of both. So I downloaded 2019 and have both running side by side, I also noticed 2019 shows backward compatibility to ASP.NET 2.0 which is what my old projects run on

thanks a lot
