I have an old WPF/HelixToolkit/SharpDX project from 2016 that I started working with. I was having some viewport issues and thought they might be cured by updating HelixToolkit & SharpDX packages. Unfortunately, after the updates my project will no longer compile.
I tried Build->Clean and Rebuild All, but no joy. Still getting these errors:
Severity Code Description Project File Line Suppression State
Error The "SharpDX.Toolkit.EffectCompilerTask" task could not be loaded from the assembly \SharpDX.Toolkit.CompilerTask.dll. Could not load file or assembly 'file:///C:\SharpDX.Toolkit.CompilerTask.dll' or one of its dependencies. The system cannot find the file specified. Confirm that the <UsingTask> declaration is correct, that the assembly and all its dependencies are available, and that the task contains a public class that implements Microsoft.Build.Framework.ITask. MyWPFMagViewer2
Severity Code Description Project File Line Suppression State
Warning The referenced component 'SharpDX.Toolkit.Compiler' could not be found. MyWPFMagViewer2
I'm really hoping it's something simple, but I don't have a clue what it might be. Can anyone help?
TIA,
Frank
I never found an answer to this problem, but I was able to work around it by re-cloning my project from GitHub, and not updating SharpDX

I am modifying the code from this tutorial and I'm getting this error:
Error preparing CoreML model "Resnet50.mlmodel" for code generation:
Target's predominant language "Swift Interface" is not supported for
CoreML code generation. Please set COREML_CODEGEN_LANGUAGE to
preferred language
The project used to compile before with the "Places205-GoogLeNet" model.
Anyone else experiencing the same?
In the project settings view for your app target, Change the setting COREML_CODEGEN_LANGUAGE to Swift.
The default setting Automatic is not working correctly in all cases in Xcode 9 beta.
This issue was also mentioned on the apple developer lists here.
So basically if you have got more than one model XCode does not autogenerate the code automatically and complains with an error.
Removing the previous model from the resource folder solved the issue.
It looks like that an App can have only one model installed.
Anytime I try to reference an NUNIT data type in the iOS framework, I am given a compiler error saying it can't find the IConvertible type
Error CS7069: Reference to type System.IConvertible' claims it is defined assemblymscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089', but it could not be found (CS7069) (logic)
I was able to reproduce this by creating a brand new Xamarin.Forms project that only targets iOS.
Immediately after creating it, I added a second Xamarin.Forms project, this time a PCL.
I then needed to add the Xamarin.iOS library so that I can reference the iOS specific APIs, specifically the Photos API. I did this by navigating to
~/Library/Frameworks/Xamarin.iOS.framework/Versions/9.0.1.29/lib/mono/Xamarin.iOS/Xamarin.iOS.dll
Lastly, I added a blank class to the new PCL project, and created a locally scoped NUNIT field. This is where the compiler error happens. This happens in my current project when I try to get the number of photos in a PHAssetCollection, as that is an NUNIT data type.
using System;
namespace logic
{
public class EmptyClass
{
public EmptyClass()
{
nuint test = 5;
}
}
}
This gives me the compiler error I've referenced above. How can I solve this? This has become a blocking issue for me, am I referencing the wrong Xamarin.iOS.dll? It's not available in the list of nuget packages when I scan for them, so I can't add it via NuGet. NuGet only has Xamarin.Forms.dll available.
Update 1
After trying a few different combinations, I think that I have a working solution. Instead of creating a Xamarin.Forms Library, I created a normal iOS PCL library instead. This solved that problem.
I don't know why the Xamarin.Forms library wouldn't work. Is it not intended to be used for platform specific code?
Xamarin Forms PCL's need to be platform agnostic. If you have a NUnit project that needs access to a Xamarin.iOS specific reference, then you need to build within the iOS project / iOS PCL.
Xamarin.iOS.dll can only be referenced from a iOS related project.
I have updated to Xamarin.Android 4.10.1 and now my MvvmCross project does not compile :( its as if it cant find any of the MVX attributes.
I am getting an error like the following for every MvvmCross entry in my code
E:\Software Projects\xxx\xxx\xxx\Resources\layout\xxx.xml(0,0): Error: No resource identifier found for attribute 'MvxBind' in package 'com.xxx' (xxx)
has anyone encountered this too?
Thanks

I am trying to preverify "signpost-commonshttp4-1.2.1.1.jar" file to use it in BlackBerry project
Here is the command im trying. Since it also needs "signpost-core-1.2.1.1.jar" to classpath which is already preverified.
C:\Eclipse_bb\plugins\net.rim.ejde.componentpack5.0.0_5.0.0.25\components\bin>
preverify.exe -classpath
"C:\Eclipse_bb\plugins\net.rim.ejde.componentpack5.0.0_5.
0.0.25\components\lib\net_rim_api.jar;C:\Program Files\Java\jdk1.6.0_25\jre\lib\
rt.jar;C:\Eclipse_bb\plugins\net.rim.ejde.componentpack5.0.0_5.0.0.25\components
\bin\output\signpost-core-1.2.1.1.jar"
signpost-commonshttp4-1.2.1.1.jar
Here i have added classpath of net_rim_api.jar, rt.jar & signpost-core-1.2.1.1.jar
It throws below Error
Error preverifying class
oauth.signpost.commonshttp.CommonsHttpOAuthConsumer
VERIFIER ERROR oauth/signpost/commonshttp/CommonsHttpOAuthConsumer.wrap(Ljava/lang/Object;)Loauth/signpost/http/HttpRequest;:
Illegal type in constant pool
If you mean signpost, with source code hosted on github by kaeppler, then it appears to be a Java-SE library. BlackBerry is a Java-ME device, so you will need to find a Java-ME compliant library. The preverifier errors you are seeing are the first indication that the Java-SE code won't work on BlackBerry.
