Static "EntityFrameworkManager.ContextFactory" is an issue for multi-context apps

[gordon-matt]

I was playing with the Extensions recently and noticed this error:

"A default DbContext context must exist, or a context factory must be provided"

I found out that I need to setup a context factory like so:

EntityFrameworkManager.ContextFactory = context => new ApplicationDbContext();

This is all well and good if the app only has one context.. but we have multiple databases, so there's multiple contexts. So you can see that EntityFrameworkManager.ContextFactory being static is a problem.

Is there a solution to this?

Hello @gordon-matt

Indeed, in our Context Factory documentation, you can find an example:

// Using a constructor that depends on the current context
EntityFrameworkManager.ContextFactory = context =>
{
	if (context is EntityContext)
	{
		return new EntityContext();
	}
	else
	{
		return new ElseContext();
	}
};

As you can see, you can use the context passed in parameter to know which type of context should be returned.

Let me know if you need more assistance.
