MSBuild: The Microsoft Build Engine is a platform for building applications. This engine, also known as MSBuild, provides an XML schema for project files that controls how the build platform handles and builds software. Visual Studio uses MSBuild, but MSBuild doesn't depend on Visual Studio. By calling msbuild.exe in a project or solution file, you can schedule and build products in an environment without Visual Studio installed.

Barabala said so much, as can be seen from the name, he is the compiler of Microsoft, that is, programming projects into executable programs, etc.
Used before, modify the code using txt notepad, recompile with msbuild, as follows:
Roslynis an open-source .NET compiler from Microsoft Corporation. The compiler supports C# and Visual Basic code compilation and provides rich code analysis APIs.
We try to create a new one.NET framework 4.6project, using VS 2019 will generate the MSBuild Project Generate Output Detail setting normally, as shown in the image below:

Downloaded from other articles on the Internet, for reference only:
The .NET Framework 4.0's built-in MSBuild doesn't recognize C# 6.0 syntax features.
"MSBuild" => msbuild.exe, "Roslyn" => csc.exe
MSbuild is Visual Studio's build system. It calls the C# compiler to compile the C# project. Roslyn is a C# compiler (and VB compiler). Therefore, msbuild uses Roslyn.
However, Roslyn contains more than just a compiler. It also includes a VS plugin that gives you IDE features (completion lists, colors, code fixes, etc.).
In addition, Roslyn is an API for analyzing source code, which you can use in your own applications. For the last case, there is an API called MSBuildWorkspace that can be used to open a project or solution for analysis. This workspace uses MSBuild to find out all parts of a project and solution. Therefore, this part of Roslin uses MSBuild.
Summary:
My own understanding is that MSBuild is a collection of Microsoft compilers, and he may not be responsible for compiling the generation, but he will help us call Roslyn to compile the c# code. He can also compile code in other languages and then call other corresponding compilers.
For compiling C# projects, MSBuild is the decision-maker and Roslyn is the executor.
