compile error when compiling C# code with the CSharpCodeProvider class RRS feed

  • Question

  • The situation is that i have an application which is using assembly redirection (https://msdn.microsoft.com/en-us/library/7wd6ex19(v=vs.110).aspx) to be able to use assemblies that have a different version at run-time then what version was used for building the assemblies. This is working, except for when i try to compile some additional code in C#, using the CSharpCodeProvider class. This is returning an error 'Assembly A version=X1 uses B, version=Y2 which has a higher version than referenced assembly B, version=Y1'.

    Is there something additional i need to do to make the CSharpCodeProvider aware of the assembly redirection ?

    This is how i compile the code :

    public static CompilerResults CheckSyntax (string code)
        List<string> dllList = <list of DLL names>;
        CompilerParameters parameters = new CompilerParameters(dllList.ToArray(), <output DLL name>);
        CSharpCodeProvider codeProvider = new CSharpCodeProvider();
        return codeProvider.CompileAssemblyFromSource(parameters, code);

  • Hi Kris,

    How about the result if you don't use  assembly redirection?

    Or could you also show a simplified demo here or a screen capture?

  • Without assembly redirection the application will not start.

    (This is .NET framework version 4.0 by the way.)
