I am trying to send an email with attachment from WSO2EI6.6. The code is working as expected when I tried with some text as email body. When I tried to send HTML content, it is not working as expected. The HTML code is for a table and I am expecting to see the table in email body but the HTML code is displayed in email body as text.

I'm using service fabric on premisse with my micro services and I adopted the strategy of using dynamic ports, but apparently I think I've narrowed the range of ports because I've reached the limit of 25 applications with approximately 340 microservices in steless. and when trying to upload a new application it error in almost all services. if you remove an old one for example the application that was giving error goes up and stays stable. I have already increased the port range in clustermanifest in the parameter: ApplicationEndpoints but did not have effect ...

I am not 100% sure whether the issue you have is about available ports but if it is - can you check this documentation section?
FROM DOCS:
ephemeralPorts override the dynamic ports used by the OS. Service Fabric uses a part of these ports as application ports, and the remaining are available for the OS. It also maps this range to the existing range present in the OS, so for all purposes, you can use the ranges given in the sample JSON files. Make sure that the difference between the start and the end ports is at least 255. You might run into conflicts if this difference is too low, because this range is shared with the OS. To see the configured dynamic port range, run netsh int ipv4 show dynamicport tcp.
applicationPorts are the ports that are used by the Service Fabric applications. The application port range should be large enough to cover the endpoint requirement of your applications. This range should be exclusive from the dynamic port range on the machine, that is, the ephemeralPorts range as set in the configuration. Service Fabric uses these ports whenever new ports are required and takes care of opening the firewall for these ports.
These settings are configured for each nodeType in the cluster configuration.
In the ClusterManifest.xml (based on ClusterManifestType XML Schema) these settings are represented by ApplicationEndpoints and EphemeralEndpoints elements within NodeType element.
On the Details page of the cluster, in the section Load Metric Information, I can see constantly changing values for Action column.
It is changing from Creation to CreationWithMove and back again for Count, PrimaryCount and ReplicaCount. For other entries it shows NoActionNeeded.
What does that mean? And can it cause timeouts on client-side connecting to the cluster?

I encountered with the same behavior, and after a little trial and error, I found out that it happens with stateless applications (I’ve tested only 2 so far) that has instance count of -1.
When I set the instance count to any number in range 1..<number_of_nodes>
the Action value of Count, PrimaryCount and ReplicaCount metrics under Load Metric Information table in the Cluster DETAILS tab no longer changes every second to Creation and CreationWithMove, instead it stays NoActionNeeded.
Using .Net 4 with EF 1.0: I have a table per type inheritance database structure and edmx (see diagram and cutdown edmx at the end of the post. The edmx is created through a code generator). I've just included one subtype for this post but there are many!
All of our entity framework queries are also dynamically generated. So at the moment when I try to retrieve a product (which may or may not be a book) I have the following ESQL query being generated.
SELECT VALUE [tb_product] FROM [tb_product] as [tb_product] WHERE (([tb_product].[Id] = #p0))
If the object I've requested is a book, the object I'm getting returned to me is of type 'tb_product'. I can't seem to cast or otherwise access the 'book' information from this tb_product object.
How can I modify the query, edmx or some other component so that when I query the base type I can also access all relevant subtype information without a second database trip. Can I?

This worked with Firebird .NET Provider 2.6.5:
using (var context = new SetupContext())
{
_maxApplicationID = context.Application.Max(a => (int?)a.ID) ?? 0;
}

Now I have upgraded to version Firebird .NET Provider 2.7.5 and I'm getting an ArgumentNullException saying that "Value cannot be null. Parameter name: key".
Is this a changed behaviour in 2.7.5 or did somthing went wrong with the update. If this is a changed behaviour: How can I get the maximum value of a column?
If done as Mark Rotteveel suggested. This is the link to the ticket in the firebird bug database: http://tracker.firebirdsql.org/browse/DNET-429
Our app. has a complex set of security rules.
I've implemented the rules in a SQL Statement, then translated it to Linq to SQL and the Entity Framework. the EF one was having some performance issues due to the nature of follow-up queries that have to take place on the data set, so I figured it would be best to just have the filtering done in SQL where I have maximum control over the statement that is executed, to ensure performance. I fit it in a View, thinking I'd let EF use that as a basis & continue the rest of the filtering there, but I am having trouble mapping the existing tables to the view.
As you can see on the screenshot, all three columns are identified as Entity Key. The problem is that I can't define a FK for a View, so EF doesn't know how the connections are to be made. When I try to manualy create them, EF complains I need to specify a connection to all three columns (for a single relation), which is not possible. I've also tried it from the other end, but no dice.

In the vwEntitiesFilter just click the field id, right click properties and in the properties window set "Entity Key" = false
Then in toolbox, chose association and associate user.id field with vwEntitiesFilter.user_id and entity.id with vwEntitiesFilter.entity_id.
This just allow you to make the relations
