I have created a project with Visual Studio 2017 on my PC at home. But when I try to open it with SharpDevelop it says:

"The tools version "15.0" is unrecognized."

My SharpDevelop is on a USB stick, so I use it on different computers. Is there a way to fix this or can I change the tool version somehow?

It depends on if you are using any feature specific to the 15 toolchain, but if you are not you should be able to open the .csproj with a text editor and change the tools version down to 14.

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="14.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">

If the above does not work for you, recreate the project in Visual Studio 2015; that will use the 14 tools version. You should be able to open the project in Visual Studio 2017 and in SharpDevelop.
