C# Roslyn LSP Configuration
The details below describe how to install and configure roslyn-language-server found
here.
Installing the Language Server
To install the language server run the following command:
roslyn-language-server --stdio --autoLoadProjects
Configuration
Start Zeus and use the
Options, Document Types menu to edit the
C# Document Type and in the
Language Server panel apply the following configuration settings:
Program Type: Batch
Program: roslyn-language-server.cmd
Directory: $wdd
Arguments: --stdio
