SlnMerge merges the solutions when creating solution file by Unity Editor.


Works with

  • Unity 2018.4.5f1 + Windows 10 and macOS 10.15
  • Microsoft Visual Studio 2019
  • JetBrains Rider 2019.2

How to use

1. Copy src/SlnMerge.cs to Assets/Editor in your Unity project.

2. Create ProjectName.sln.mergesettings and configure a target solution.

Create a setting XML file named <ProjectName>.sln.mergesettings.

For example, when the project name is MyUnityApp, Unity Editor generates MyUnityApp.sln. You need to create MyUnityApp.sln.mergesettings.


You can specify the target solution to merge by MergeTargetSolution element.

NOTE: If you don't have the settings, SlnMerge uses ProjectName.Merge.sln as a target.


Add projects to solution folders

You can use NestedProjects settings to move projects to solution folders. When a solution folder doesn't exist, SlnMerge will add the solution folder to the solution automatically. But, you need to define a solution folder as SolutionFolder in mergesettings.

        <!-- Define a solution folder named 'Unity' with GUID -->
        <SolutionFolder FolderPath="Unity" Guid="{55739033-89BA-48AE-B482-843AFD452468}">
        <NestedProject ProjectName="Assembly-CSharp" FolderPath="Unity" />
        <NestedProject ProjectName="Assembly-CSharp-Editor" FolderPath="Unity" />
