We have a workflow with several activities in a strong-named assembly. While the workflow is waiting for a user action, we update the assembly to a newer version. On the next step execution, workflow foundation suddenly says that it can no longer find the workflow instance. This is literally about the assembly version number. If we don't change the version number, it keeps working. The exception additional information is:
The execution of the InstancePersistenceCommand named {urn:schemas-microsoft-com:System.Activities.Persistence/command}LoadWorkflowByInstanceKey was interrupted by an error.
The fault code name is InstanceNotFound .
Has anyone encountered something like this?

A strange error suddenly cropped up on our Dynamics CRM 2011 server - a specific plugin assembly can not be found when the plugin execution is triggered through a workflow process, with the error:
[Microsoft.Crm.ObjectModel: Microsoft.Crm.ObjectModel.SyncWorkflowExecutionPlugin]
[324f29aa-6082-ea11-80ee-005056837add: ]
Starting sync workflow 'workflow name', Id: 2d4f29aa-6082-ea11-80ee-005056837add
Sync workflow 'workflow name' terminated with error 'The type initializer for '<Module>' threw an exception.'
And exception stack trace ultimately leads to:
Inner Exception: <CrtImplementationDetails>.ModuleLoadException: The C++ module failed to load while attempting to initialize the default appdomain.
at <CrtImplementationDetails>.ThrowModuleLoadException(String errorMessage, Exception innerException)
at <CrtImplementationDetails>.LanguageSupport.Initialize(LanguageSupport* )
at .cctor()
Inner Exception: System.Runtime.Serialization.SerializationException: Unable to find assembly 'AssemblyName, Version=8.75.0.267, Culture=neutral, PublicKeyToken=4e4051c21cef725b'.
The assembly is present on the server, version, culture, and public key token all match. Oddly enough the plugin steps work fine when the execution is triggered directly through a create/update/etc request - it's only when the execution is triggered through a workflow that the error occurs. And by triggered through a workflow I don't mean running code activity from that assembly, I mean a situation like:
Entity is created
OnCreate plugin from Assembly1 runs without issues
Workflow runs that updates a related entity, triggering OnUpdate plugin from Assembly1 - ERROR
This issue cropped up initially after a server restart. Another restart fixed it temporarily, until two days later it started happening again. We've tried everything we can think of - updating the assembly, unregistering/re-registering it, restarting all services, restarting the server again. Does anyone have any idea what might be the cause of this and how to fix it?
We discovered the issue was caused by a Windows update that had been applied before the initial restart, which had installed .NET framework v4.8 on the server. Although the application was still using an older version, apparently just having v4.8 installed was enough to cause errors. Reverting back to an earlier .NET version fixed the problem.
I am not certain what is the exact technical reason for this - seems to be something related to App Domains (https://learn.microsoft.com/en-us/dotnet/api/system.appdomain?view=netframework-4.8). But if you encounter a similar issue, check your .NET framework version.
My application randomly crashes on my target machines with an .net failure. In mscorelib.dll there seems to be a System.InvalidCastException.
The error occures in:
System.Threading._ThreadPoolWaitOrTimerCallback.PerformWaitOrTimerCallback(System.Object, Boolean)
and the reason is:
Unable to cast object of type 'System.Threading.ManualResetEvent' to type 'System.Threading._ThreadPoolWaitOrTimerCallback'.`
The Application runs multiple times on the target machine (win7 x64).
The Application is a x86 application.
There have never been issues before I was forced to compile the Application to the .net 4.6+ target framework. But I need to go up to at least 4.6 due to other dependencies now.
I thought it could be a issue with garbage collection and set <gcConcurrent enabled="false"/>. But this did not help.
I tried to debug the miniDumps with WinDbg. But I was not successful to find a way to track the Issue down to a specific line of code or a method in my code. I don't think it is a .net issue, but I have no clue how to find the corresponding line in my code.
Edit on request:
Former .net target framework: 4.5.1
The application crashes randomly, could be after more than 24h
I'm not able to figure out in which part of my code the application crashes
The same application runs independent parallel on the same machine. Sometimes randomly one or two instances crash.
I have a such code (It's a part of unit tests executed by nunit-console):
class MyClass
{
[DI(Type = typeof(MyClass))]
public IMyClass MyClassProperty {get;set;}
}
By reflection i'm scanning such classes and then register in Autofac:
// Register MyClass as IMyClass
autofacBuilder.RegisterType(diAttribute.Type).As(propertyInfo.PropertyType);
After that i need to resolve this property in the same way - by reflection:
autofacContainer.Resolve(propertyInfo.PropertyType) // it contains IMyClass
When I'm launching this code locally it works well.
But doesn't work on TeamCity. Fails with error:
Error: 'Autofac.Core.DependencyResolutionException: An exception was thrown while executing a resolve operation. See the InnerException for details. ---> Common Language Runtime detected an invalid program. (See inner exception for details.) ---> System.InvalidProgramException: Common Language Runtime detected an invalid program.
There are a lot of questions on StackOverflow about this exception. It's not an Autofac problem, it's a JIT compiler problem. A quick Google search on the exception yields a lot of info.
InvalidProgramException / Common Language Runtime detected an invalid program
Common Language Runtime detected an invalid program?
You even see projects like NewtonSoft.Json running into the issue.
The exception itself means "a program contains invalid Microsoft intermediate language (MSIL) or metadata; generally this indicates a bug in the compiler that generated the program."
Microsoft has a KB article on troubleshooting the issue. Whenever folks have resolved it, as far as I've seen, it's always one of two fixes:
A change to the compilation options. For example, some people running encryption/obfuscation sorts of tools find turning them off helps; others find turning off compiler optimization fixes it. (The KB article has some tips.)
Making sure things are patched to the latest versions. I've run into other similar situations myself where things work great on my machine but not on the build server; or vice versa. Almost invariably it's because I have my machine all patched up but the build server has been languishing unpatched; or someone just patched up the build server and I haven't installed my patches yet.
I'd recommend starting with the patches since that's usually the simplest fix. Use Windows Update to make sure both you and the build server have the latest .NET updates. If that doesn't fix it, check out some of the troubleshooting tips in the articles and questions above.
I am using a windows service, In which I am having a reference of an assembly which is copy local= false. But I am trying to load it at runtime, which is though working fine when I am running it from visual studio, But when I try to install it, cmd gives this error:
An exception occurred while trying to find the installers in the D:\Official\Pro
jects\20131007_ImproveDN\build\debug\application

ot fully revert to its initial state after the rollback is complete.
Also one thing to note here is that If I make copy local true of that .dll it makes installation fine. BUt I dont want to load it before installation so I want to do it at runtime.
Thanks in Advance.
Maybe you need to use another version of InstallUtil.exe:
c:\Windows\Microsoft.NET\Framework\v2.0.50727\InstallUtil.exe
c:\Windows\Microsoft.NET\Framework\v4.0.30319\InstallUtil.exe
c:\Windows\Microsoft.NET\Framework64\v2.0.50727\InstallUtil.exe
c:\Windows\Microsoft.NET\Framework64\v4.0.30319\InstallUtil.exe
Try to use x64 version from Framework64 subfolder.
Also one thing to note here is that If I make copy local true of that .dll it makes installation fine. BUt I dont want to load it before installation so I want to do it at runtime.
That doesn't really matter, the assembly still needs to make it to the installation directory. If you set Copy Local to false, then you still need to distribute the assembly with the installation.
I had a similiar problem. I did the following that worked for me.
First, use FuseLog (Assembly Binding Viewer) to figure out where the binding is failing (Described Here
Once I began getting logs, I noticed this in my log was "Invalid assembly platform or ContentType in file (hr = 0x8007000b)."
My solution consisted of 3 projects. I went through the build properties of each project and noticed that one of them was targeted for "x86". I changed it to "Any CPU", recompiled and the problem was resolved.
I have a reference to a MySQL.Data 5.2.3 assembly in a data layer, great. I currently I have small console app inteh same solution referencing JUST THIS data layer which connects just fine. I then created a unit test project (also in the same solution) and reference that same data layer project, and from that I get:
Test method LTTests.WrapperTest.LoginTest threw exception: System.IO.FileLoadException: Could not load file or assembly 'MySql.Data, Version=5.2.3.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d' or one of its dependencies. Strong name signature could not be verified. The assembly may have been tampered with, or it was delay signed but not fully signed with the correct private key. (Exception from HRESULT: 0x80131045).
So I'm trying to understand...I can do this for a console exe and it works but not a unit test? This makes me nervous to build on something apparently flawed, but I'm at a loss for what to do next. I'm lost, I've been re-adding various things looking for what the deal is and I have no clue.
The exception is from the data layer and not from the test (per the stack) so it's like the test is calling the layer's method (duh) and the data layer is puking but not for the console?
Thanks.
This is not the answer why there is an error but a possible way to find it out:
You can use the "Assembly Binding Log Viewer" (Fuslogvw.exe) that belongs to the dotnet sdk to find out what is loaded and why.
If logging is enabled it can show you wich assemblies are loaded from which directory and which assembly caused it to load.
For details see http://msdn.microsoft.com/en-us/library/e74a18c4(v=vs.80).aspx
so may be there are different version of MySql.Data lying around and the error message means i.e. that the version number found is not the one it expects.
