Failed to resolve System.Data.Linq - SyntaxEditor .NET Languages Add-on for Windows Forms Forum

Posted 16 years ago by Miha Markic - Righthand

Hi guys,

DotNetProjectResolver fails to resolve System.Data.Linq system assembly even thoug the application is marked as full trust (in clickonce settings).
It throws: MethodAccessException: a..ctor().
Why are you creating instances from that assembly?
Note: the problematic assembly is not referenced by application - perhaps this is the problem?

Hi Miha,

It isn't creating anything in your assembly. That code is trying to create a ProjectContentLoader, which is an internal class in our assembly.

It sounds like it won't let the ProjectContentLoader's constructor be called properly. Any idea why?

Hi guys,

Is there a way to attach file to these posts?
I don't know why this is happening but I guess it has something to do with security.
Here is the repro. Create winforms project and place this code in Form1.cs:


protected override void OnLoad(EventArgs e)
{
    if (!DesignMode)
    {
        DotNetProjectResolver resolver = new DotNetProjectResolver();
        string path = Path.GetTempPath() + @"\Test";
        if (!Directory.Exists(path))
            Directory.CreateDirectory(path);
        resolver.CachePath = path;
        resolver.AddExternalReferenceForSystemAssembly("System.Data.Linq");
    }
    base.OnLoad(e);
}

Make sure you check Project Properties/Security/Enable ClickOnce Security Settings and run the sample.
You'll get this excetion on Add.. line. Note, this is happening only to assemblies not referenced by the project itself.

Thanks I think we found the problem. The AppDomainSetup we pass to create the AppDomain needed to pass some trust info along as well. When we do that it gets past your sample and displays the form ok. This will be in the next maintenance release.
