    The CLR is the runtime. If you have no runtime exactly how would a .NET app run? You literally would have deleted the runtime that the app needs to run. It would be equivalent to running a Windows app without Windows.

    What exactly is your goal? Are you trying to get a xcopy-style app that doesn't require the runtime to be installed? If so then look into a .NET Core/5 self-contained deployment here.

    See Common Language Runtime (CLR) overview - .NET. It refers to the Common Language Infrastructure (CLI). The CLI is the standard and the CLR is Microsoft's implementation of it. The C# Language Standard (version 5.0): ECMA-334.pdf (Annex C. Standard library) says:

    A conforming C# implementation shall provide a minimum set of types having specific semantics. ... For a formal
    definition of these types and their members, refer to ISO/IEC 23271:2012 Common Language
    Infrastructure (CLI)

    The C# language standard requires the CLR or an equivalent.

    Not sure what you want to achieve by using C# without CLR. Your only option is to use RemObjects' C# that allows you to use other runtimes (like Java, native Win32 and WebAssembly) instead of .NET CLR,
