Question Do I need a solution file?

[David Ong]

I am new to 2022 version of VS. The solution file from a previous version of VS is having errors and is disagreeable with VS2022 so I opened VS2022 first instead of double clicking on the sln file and selected the directory and the program runs fine. But for my convenience is it possible to regenerate a solution file for 2022 so that I can just double click on the new sln file instead of starting VS 2022 first and the looking for the directory?


Regards, David

VS 2022 should be able to open any solution file created in VS 2010 or later without any issues and some created before that too. Maybe you should explain what the actual issue(s) is and maybe we can address that. Depending on how old it is, VS 2022 might make some small changes to older solution or project files but that upgrade process is automatic and almost never causes any issues. Maybe you've done something wrong or maybe something has become corrupted. We can't help if we don't know what the issue is.

If you want a new solution then you have to create a new solution. Once you have a new solution and project open in VS, you can import items, e.g. forms and other classes, from your existing project into the new one. Once all the items have been imported and any additional configuration done, you can treat that new solution and project the same way you would any other.

My files were originally from Visual Studio 6.0 then all of a sudden I decided I will try to upgrade it to something more sensible, I tried to upgrade to 2010 but there were some issues, then to 2019 I think thats how the sln file was created then finally to 2022. But the sln file was being rejected by 2022. Is that enough info? Also it is a dll project in c++.

VS6 predates .NET and most, if not all, file formats will be different. You generally cannot simply open a VS6 project in VS 2022 and have anything useful happen. Microsoft used to have a wizard for upgrading VB6 projects to VB.NET but that went away between VS 2008 and 2010. I don't work with C++ so I'm not sure what the situation is for C++ projects. Because they are still using the same language as before, they may also still be using the same project file format as before. I really have no idea and I'm afraid that this isn't really the place to look deeper into it, given that this site is dedicated to VB. One option you could try is to create a new project in VS 2022 for an unmanaged C++ library (assuming that's possible; I guess it is but I'm not even sure) and see what the project structure looks like compared to what you already have.

Again, I've don't use C++ but I don't see why a solution file created in VS 2019 would not work in VS 2022. Again, you need to explain the specifics of the problem. "Rejected" could mean any number of things. Tell us what actually happens.
