around this issue I couldn't quite find the answer I was looking for searching through stack so Im posting this. , You're looking for a generic method:
code :
private static void SetEntityPropertiesRequired<TEntity>(DbModelBuilder modelBuilder)
{
    //set all decimal properties in Projection Entity to be Required
    var decimalproperties = typeof (TEntity).GetProperties()
    ...

Strange EF behaviour when passing DbSet to a method with parameter type IEnumerable<>

Strange EF behaviour when passing DbSet to a method with parameter type IEnumerable<>

This might help you You must change it to IQueryable because if you pass it as IEnumerable you actually execute query SELECT * FROM Product. Your method starts iterating the result set but your projection calls x.ParentProducts.Select(p => p.Id) which results in lazy loading of ParentProducts navigation property. Lazy loading opens second active data reader which is possible only if you have it enabled in connection string.

should help you out For this, I would actually suggest using reflection. In the constructor of your DbContext, you can set a property to the function pointer:
code :
method = this.GetType().GetMethod("Set", new Type[0]).MakeGenericMethod(typeof(UserImplementation));
method.Invoke(this, new object[0]);

I wish this helpful for you You can pass values of a,b,c as an array and along with them pass function x and y as parameter to your function
code :
function x(a, b, c){
    console.log(a + b + c);
}

function y(a, b, c){
    console.log(a + b + c);
}

function root(param, fn1, fn2){
    var a = param[0];
    var b = param[1];
    var c = param[2];

    fn1(a,b,c);
    fn2(a,b,c);
}
root([1,2,3],x,y);

Does that help Can you not run the Cast method on the DbSet again?
