Method not found: 'Int32 System.Runtime.InteropServices.Marshal.SizeOf(!!0)

[Robert Carrington]

I'm getting a Method not found: 'Int32 System.Runtime.InteropServices.Marshal.SizeOf(!!0)'. error when calling CSScript.LoadCode(String scriptText, String[] refAssemblies) when running my application on a Windows Server 2008 R2 Standard machine with .net 4.5 installed.  If I run the same code on my Windows 7 .net 4.5.1 machine it works fine.  I'm using CS-Script v3.7 (via NuGet).  I found the following article: https://csscriptnpp.codeplex.com/wikipage?title=FAQ that gives a possible cause for the issue, however as far as I can tell I'm using the latest version and would never have used a version that was old enough to be a problem.  Does CS-Script require 4.5.1 now?  Is it possible this is caused by my script referencing something that requires 4.5.1 (I don't think it is)?

full error:

Method not found: 'Int32 System.Runtime.InteropServices.Marshal.SizeOf(!!0)'.

The problem was caused by undesired (and accidental) compiler optimization of the binaries for that specific release. Please get the latest release from NuGet or from CodePlex. This should solve your problem.

Cheers,

Oleg

I'm not sure what was going on with this.  As far as I can tell I was always on the latest release and had never had the bad release, however today everything is working fine on both machines so something happened - probably some stupid mistake on my part.  Sorry for wasting your time.

Not a problem. None was wasted. 

Have a good day,

I've just managed to reproduce it again and I'm definitely use v3.7 (via NuGet).  For most functions it works but the following code fails:

string scriptText = @"using System; class Script { public static Func<dynamic, bool> GetFunc() { return e => e.EventType == \"test\"; } }";

AsmHelper script = new AsmHelper(CSScript.LoadCode(scriptText)); // throws Method not found exception

Func<dynamic, bool> result = script.Invoke("Script.GetFunc") as Func<dynamic, bool>;

The full exception is:

Method not found: 'Int32 System.Runtime.InteropServices.Marshal.SizeOf(!!0)'.

But this is exactly the problem. The latest NuGet version is v3.8.8 not v3.78

[Robert Carrington]

bah! I guess I need to learn to use nuget.  I could have sworn I visited that page yesterday and ran Update-Package and it still showed 3.7.  Ran it now and it's updated properly.  I'm questioning my sanity right now!

I also just realised I could do exactly what I wanted using CSScript.Evaluator.LoadDelegate<T>() anyway and that bypassed the problem too.

Thanks again,

Rob
