How to Create a DLL of .csproj file

csc /target:library /out:MyMaths.dll ClassLibraryFunction.csproj

I am using this code to generate a DLL in VS.Cmd compiler for a whole solution. However, I am getting a compile error, and the DLL is not being generated.

Solution

  • csc does not work with .csproj files. You have a few options:

    1. use msbuild; for example

      msbuild ClassLibraryFunction.csproj

      noting that you may need to change the output-type of the project (in the IDE this is Project Properties, Application, Output type; in the csproj file this is <OutputType>Library</OutputType>)

    2. use csc with the /recurse switch; for example:

      csc /target:library /out:MyMaths.dll /recurse:*.cs

      (which will compile all the .cs files in the current folder or in sub-folders)

    3. do nothing whatsoever, and just use the exe that you already have; a .NET exe can be referenced just like any other assembly, and any public types can be consumed
