Im currently making a app that needs to download some raw data from the internet, the problem is that the app is compiled by another c# app (builder), so im using the CSharpCodeProvider which generates .NET 4 assemblies.

The problem now is that when using WebClient or HttpClient in .NET 4 it says

Could not create SSL/TLS secure channel

Is there a method to download stuff like that in .NET 4?

Download function:

static async Task<byte[]> GetData()
        {
            HttpResponseMessage response =
                await new HttpClient().GetAsync(Url);
            return await response.Content.ReadAsByteArrayAsync();
        }

Compiler:

var providerOptions = new Dictionary<string, string> { { "CompilerVersion", "v4.0" } };
using (var provider = new CSharpCodeProvider(providerOptions))
{
    var compilerParameters = new CompilerParameters
    {
        GenerateExecutable = true,
        OutputAssembly = outputExe
    };

    if (iconFile != null)
        compilerParameters.CompilerOptions = $@"/win32icon:""{iconFile}""";

    if (references != null && references.Length > 0)
        compilerParameters.ReferencedAssemblies.AddRange(references);

    CompilerResults results = provider.CompileAssemblyFromSource(compilerParameters, sourceCode);

    if (results.Errors.HasErrors)
    {
        string errors = string.Join(Environment.NewLine, results.Errors.Cast<CompilerError>().Select(e => e.ErrorText));
        MessageBox.Show($"Compilation failed:{Environment.NewLine}{errors}", "WT Error");
    }
}

I tried to get raw data from internet but I got a error.
