I am not sure what is the problem here. I tried to know better about this exception but all the details refer to the C# programming.

I use Postgresql-13 in my ASP MVC NET 6 project, occasionally, I face this issue below:

my ConnectionString to Postgresql-13 was:
"Server=xxx.xxx.xxx.xxx;Database=mydb;User ID=myuserid;Password=mypassword;Keepalive=30; Connection Idle Lifetime=300; Tcp Keepalive=true";
my postgresql.conf
shared_buffers = 256MB
and my sysctl.conf
kernel.shmmax=100663296
why did it happen?, what should I check?
Potential causes are:
Session had hit an inactivity timeout and was terminated. ==> You can try adding/changing CommandTimeout parameter to more than default of 30 seconds.
Connection used an authentication token, which had expired.
Database connection listener service had been restarted, possibly due to patching or automated code deployment. ==> You could add code to reconnect and run a simple "heartbeat" query like SELECT CURRENT_DATE;
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?
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.
I have a few Silverlight applications in my website. Each are on their own page and do not interact with each other. I'm using Silverlight 5 and WCF Data Services for data access.
IE has been working great, but when I switch between the two while the first one is in the middle of getting data from the WCF Data Service (or we also have a .aspx page that is serving up xml in the code behind and it happens there as well).
It's throwing some seemingly random exceptions and I'm not sure how to handle them. Any ideas on how to avoid these, or cancel calls when the url changes in FF?
Chrome reports my WCF Data Service webget request as canceled and undefined.

It seems to me that you are having a timeout exception. Try increasing the timeout option of your service.
Also, sometimes you can get this exception if you have a problem with the security related setting of WCF service endpoing. Try disabling it (for testing purposes) and see if you still get the problem. More info about how to disable it here.
