.sln or .csproj which one do I turn into a .wsp?

Question

I am wanting to create a wsp from my solution but I am wondering which one I turn into the wsp, the .sln or the .csproj?

Answer 1

Open solution in Visual Studio.

Right click on the solution and deploy or build the solution.

Now check your solution configuration

If your are in debug mode, then find your .wsp in the following folder

PathOfYourSolution\bin\Debug

If your are in release mode, then find your .wsp in the following folder

PathOfYourSolution\bin\Release

Answer 2

You can have multiple SharePoint projects (.csproj) in the same Visual Studio solution (.sln). Each SharePoint project builds into a WSP (right-click on the project and select "Package" or "Publish" depending on your version of VS). "Package" (or "Publish") will first build the project and then create the .wsp.

A Visual Studio Solution (.sln) is not at all mapped to the SharePoint solution (.wsp) concept!

Answer 3

You can't turn .sln into a WSP. A .csproj created using appropriate SharePoint project template is turned into a WSP when you choose to deploy.

I think you'll find this video valuable. In it I describe what a Solution Package (WSP) is and how to create and deploy one. Although the video was recorded for SharePoint 2010, the material applies to SharePoint 2013 and 2016.
