Exception has been thrown by the target of an invocation. (REDIS Cache) - sql-server

I'm trying to resolve an issue we have specific to using REDIS cache on our web apps but need help understanding the stacktrace.
We intermittently get Exception has been thrown by the target of an invocation logged in our error table when users are viewing the report viewer, but there are no signs client side that anything has gone wrong.
I've had a read through this article: How to solve: "exception was thrown by the target of invocation" C# however it doesn't seem to cover our specific issue.
The stacktrace logged by our logger;

Looks to be an issue during Deserialization. Could the class definition have changed between when it was serialized and when it is being deserialized?

Why am I getting "Unable to load the specified metadata resource" error?

I have an MVC5 web application which I usually develop using my laptop.
I am trying to get the app running on my main machine at home for home-working days but have a problem connecting to the local dev database on SQL Server - when I start the app I get the following error:
More info 30/11/16:
Note that the model is generated from EDML using Entity Developer
Unable to load the specified metadata resource. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
The solution consists of 2 projects, one of which is an entity model project which is generated from EDMX.
Note: On my main machine (where it isn't working) the connection string in Web.config is the same as the machine where it works except for Data Source which refers to the SQL Server name on the main machine - I have checked this is correct several times:
I have read several Stack Overflow posts with similar issues - most point to something wrong with the path to the csdl, ssdl, msl part of the connection string.
I have:
Checked the server name is correct in the connection string
Checked the database name is correct in the connection string
Checked the database exists and is available
Checked each of the three files are where the connection string says they are (they are)
Tried using wildcard in the connection string: res://*/dllname.csdl|res://*/dllname.ssdl|res://*/dllname.msl
Update 30/11/2016:
From the suggestions in this link I have:
Checked the MetadataArtifactProcessing property - it is not set to Copy to Output directory
Checked the connection string
We don't have a post-compile task
From the suggestion in this link I have tried setting the connection string connectionString="metadata=res://*/;

There's a very popular question over there and from its rating I can assume it helped a lot of people. It even mentions a blog post with complete troubleshooting for this problem. Also, this answer looks like something you didn't try yet.

MsDeploy with DbDacFx provider and Database reference

We are using DbDacFx provider to sync our production machine.
We have ssdt database project in our solution that we deploy along with our website.
The A.sqlproj has references to master.dacpac and another database project's dacpac, say X.dacpac.
All dacpacs are in same location for deployment.
When we try to deploy the A.dacpac we get errors as below:
Info: Deploying package to database: Faulted. Error: The reference to external elements from the source named 'X.dacpac' could not be resolved, because no such source is loaded. Error: The reference to external elements from the source named 'master.dacpac' could not be resolved, because no such source is loaded. .....above errors repeated multiple times.....

Need to know how we can overcome the issues.
Thanks
Yatin.
Do the referenced dacpacs exist on the machine that is running the deploy?
If they do the easiest is to copy the dacpacs into the same folder as the dacpac you are deploying as the same directory will be checked, failing that the original path that contained the original dacpac.
This is still a pain.
We plan on scripting the sqlpackage.exe file command through runCommand provider and get automation going !!
Closing the question.
Thanks

Random InvalidOperationException on application startup

I am experiencing a problem at application startup from time to time on production machines. It doesn't happen every time the application starts, and apparently it only happens on reboot. The application is started from login, added to HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Run.
Apparently, the problem is more frequent when resetting the machine, than during a reboot. Starting the application manually after it crashes is successful.
The following exception is thrown during startup:
Initialization of 'System.Windows.Controls.TextBlock' threw an exception.
System.Windows.Markup.XamlParseException: Initialization of 'System.Windows.Controls.TextBlock' threw an exception. ---> System.InvalidOperationException: The calling thread cannot access this object because a different thread owns it.

at Exception.Occurs.At.Different.Origins.Between.Startup()
As seen from the StackTrace, there is something going on while updating style cache. I haven't been able to reproduce this on my own computer. There are no threads involved here while starting the application, but there are a few AppDomains. The origin of the exception is not always the same, but it is exactly the same from Application.LoadComponent(Object component, Uri resourceLocator)
Because our application needs to find the configuration file from a different location than the executable (..\ProgramData....) depending on the OS, we use a separate AppDomain where we instruct it where to look for the configuration file, as we could not find any better solution of telling ConfigurationManager where to look for the file. It could of course, be related to this, though not necessarily. EDIT: ConfigurationManager.OpenMappedExeConfiguration Doesn't seem to work, as it won't refresh any user or application settings accessed through Properties.Settings.Default, etc.
Does anyone have any suggestions or recommendations on how to deal with this? Sorry I am not able to provide you with a sample to reproduce with.
That exception was because you are modifying a visual element from a thread that is not the visual one. I know this because in the first line of your exception it said:
Initialization of 'System.Windows.Controls.TextBlock' threw an exception. System.Windows.Markup.XamlParseException: Initialization of 'System.Windows.Controls.TextBlock' threw an exception. ---> System.InvalidOperationException: The calling thread cannot access this object because a different thread owns it.
All the rest of the exception doesn't matter. I think it is when you are loading the initial configuration, then you use other thread. The random behavior could be that some time you find the configuration before the TextBlock control is loaded, so this times the exception will no be thrown.
To solve this please take a look to this question, and the last answer that I give (the one that use the SynchronizationContext, that really works with WPF application that use several threads). If is not clear comment and I will write the solution here.
Hope this answer helps to find that random error, its are the worsts...
I'm not sure what is causing this exception but I there is a workaround to your problem.
Instead of creating a separate AppDomain just for loading a different configuration file, you could use ConfigurationManager.OpenMappedExeConfiguration which allows you to load any .config file from anywhere in your local file system.
You use it like this:
//Map the new configuration file.
var configFileMap = new ExeConfigurationFileMap() { ExeConfigFilename = #"c:\myOther.config"};
//Get the mapped configuration file
System.Configuration.Configuration config = ConfigurationManager.OpenMappedExeConfiguration(configFileMap, ConfigurationUserLevel.None);
Use config.GetSection() to get specific sections for read-only use or directly the config object to change the configuration at run-time.
And you will not need the different AppDomain which will mean faster startup time :)
Getting rid of the extra AppDomain used to specify configuration file, and replacing it with the method specified in this link took care of the problem.

Unable to cast object of type 'MyType' to type 'Castle.Proxies.MyType'

In which situation following error occurs?
Unable to cast object of type 'MyType' to type 'Castle.Proxies.MyType'.
UPDATE:
I got this error message while binding MyType.FindAllByProperty("col1", "foo"); to a GridView (exactly a Telerik's one: RadGrid). This error is not occuring every time, just sometimes. Here is markup of my grid:
<telerik:RadGrid ID="grdList" runat="server" AutoGenerateColumns="false" OnNeedDataSource="grdList_NeedDataSource"
OnUpdateCommand="grdList_UpdateCommand" AllowAutomaticUpdates="True" OnItemUpdated="grdList_ItemUpdated"

Version Information: Microsoft .NET Framework Version:2.0.50727.4927; ASP.NET Version:2.0.50727.4927
This exception probably comes from the code trying to re-attach a proxied/lazy-loading entity to a session. The most likely API call to throw this exception with a newer NHibernate (I don't have problem with 2.1 but I do have problems with latest) is Session.Lock(obj, LockMode.None).
If the programmer of this component first evicts the entity from the ISession and then re-loads it (perhaps cached?) into another one by id, or performs ISession.Update this problem should go away until the NHibernate team has figured out the underlying problem.
I had a similar problem with EntityFramework 6.0.
I had migrated from an old version of EntityFramework that did not use proxies and had some code that created and attached new instances of the entity via new MyEntity();.
My solution was to use dbContext.MyEntity.Create(); instead so I only work with proxies. Something similar should be available for NHibernate if I recall correctly.
My error was:
Unable to cast object of type 'MyProject.MyEntity' to type
'System.Data.Entity.DynamicProxies.MyEntity_849E94C98E5E543D6DF5245252144E3EAC00131F811886276B6ABD991719D232'
We ran into the same issue with RadGrid having AutomaticInserts. After inserting an item it throw InvalidCastException: Unable to cast object of type 'MyDbModel.Role' to type 'System.Data.Entity.DynamicProxies.Role_...' in DataBind() at Rebind().
The issue was gone after I adapted the DataBinding to have an OrderBy().
