is the emf half marathon the same as the edinburgh marathon?
* enjoy a fantastic all-encompassing route which takes in some of edinburgh’s most iconic landmarks as well as offering picturesque views along the east lothian coastline. more info> directly preceding the marathon, the emf half follows the same fast and flat route, offering genuine pb potential.
hello, nicole! i've been patiently waiting to answer your question so i could give you this information as soon as it went public. announced just today, the captain america 10k and infinity gauntlet challenge have been added to the avengers super heroes half marathon weekend at disneyland® resort. i can't really say how they determine when a 10k will be added to a race weekend, while the inaugural avengers race did not offer one, the inaugural stars wars race did. i'm guessing it has to do with anticipated demand. the very first rundisney 10k wasn't introduced until 2013 during the inaugural dumbo double dare, and walt disney world® did not get its first 10k race until january of 2014, so this distance is still in its infancy. i'm so happy i could tell you about today's exciting addition! if you have plans to participate in the captain america 10k, don't forget to mark your calendar for april 7th! this is when registration opens to the public and is sure to sell out in minutes! select the highlighted link to check out this fun rundisney youtube announcement regarding this assembly of races. and please let me know if i can be of any further assistance as you begin planning to save the world one mile at a time. faith egencia has a different comp structure, though the total may come to the same. what’s the level? yes. i haven't even gotten the elite commando helmet, which i want an equivalent current source in parallel with an equivalent impedance rumourmongering notwithstanding, the answer is i don't know. 

i don't know how sophisticated the nhl's testing protocols are, and with the iihf opposed to the wada protocols of athletes having to provide their whereabouts on a 365-day basis (the ioc wants this, and team sport federations iihf, fiba, and fifa are all opposed), there are, potentially, opportunities.

with washington's roster, they will have several members of their team likely playing in the olympics, which has tougher testing standards than the nhl (among other things, a lot of otc cold medication will register a positive test).

i'm not sure about steroids. other ped's like hgh and epo, which help with recovery...without knowing how sophisticated the testing is, it's hard to answer the question.

i'll say this- "if" (and without factual evidence i don't like accusing someone of something) nhlers were to be using ped's, i'd say things like epo and hgh are the most likely options (given the rigours of their season and the marathon that is the playoffs). the league can, and should, test players throughout the season, including the playoffs.

with that being said...it's a joke what north american sports leagues punish drug cheats for when you compare the penalties outside of north america. roughly a suspension of 1/4 of a season in north america, while team sports (rugby, soccer) have 1-2 year bans for a first time offence. if the nfl, nba, mlb, and nhl were to be serious, a 2-year ban for a positive test would indicate a level of seriousness. You are mixing [expressions](https://docs.microsoft.com/en-us/dotnet/api/system.linq.expressions.expression?view=netframework-4.7.1) with [lambda expressions](https://docs.microsoft.com/en-us/dotnet/api/system.linq.expressions.lambdaexpression?view=netframework-4.7.1). There are many posts showing how you can combine lambda expressions, but the essential part is to compose expressions from lambda expression [bodies](https://docs.microsoft.com/en-us/dotnet/api/system.linq.expressions.lambdaexpression.body?view=netframework-4.7.1) and rebind the [parameters](https://docs.microsoft.com/en-us/dotnet/api/system.linq.expressions.lambdaexpression.parameters?view=netframework-4.7.1).


The later is usually achieved by a custom [`ExpressionVisitor`](https://docs.microsoft.com/en-us/dotnet/api/system.linq.expressions.expressionvisitor?view=netframework-4.7.1) like this:



```
using System.Linq.Expressions;

public static class ExpressionExtensions
{
    public static Expression ReplaceParameter(this Expression expression, ParameterExpression source, Expression target)
    {
        return new ParameterReplacer { Source = source, Target = target }.Visit(expression);
    }

    class ParameterReplacer : ExpressionVisitor
    {
        public ParameterExpression Source;
        public Expression Target;
        protected override Expression VisitParameter(ParameterExpression node)
        {
            return node == Source ? Target : base.VisitParameter(node);
        }
    }
}

```

Now regarding the EF Core combined query filters. 


Using dictionaries and expression lists seems overcomplicated for what are you doing. Since [`IMutableEntityType`](https://docs.microsoft.com/en-us/dotnet/api/microsoft.entityframeworkcore.metadata.imutableentitytype?view=efcore-2.1) provides read/write access to the [`QueryFilter`](https://docs.microsoft.com/en-us/dotnet/api/microsoft.entityframeworkcore.metadata.imutableentitytype.queryfilter?view=efcore-2.1#Microsoft_EntityFrameworkCore_Metadata_IMutableEntityType_QueryFilter), the same can be achieved with a small set of a custom extension methods.


All they go inside a class like this:



```
using System;
using System.Linq.Expressions;
using Microsoft.EntityFrameworkCore.Metadata;
using Microsoft.EntityFrameworkCore.Metadata.Builders;

public static class QueryFilterExtensions
{
}

```

First method:



```
public static void AddQueryFilter(this IMutableEntityType target, LambdaExpression filter)
{
    if (target.QueryFilter == null)
        target.QueryFilter = filter;
    else
    {
        var parameter = target.QueryFilter.Parameters[0];
        var left = target.QueryFilter.Body;
        var right = filter.Body.ReplaceParameter(filter.Parameters[0], parameter);
        var body = Expression.AndAlso(left, right);
        target.QueryFilter = Expression.Lambda(body, parameter);
    }
}

```

This is a non generic method which combines the exiting filter with passed filter using `AndAlso` (C# `&&`) operator and shows the aforementioned lambda expression combining principles.


However it's not so useful directly, like inside your entity type configuration loop (it can, but requires you to build manually the lambda expression instead of letting C# compiler do that). So here comes the second method:



```
public static void AddQueryFilter<T>(this IMutableEntityType target, Expression<Func<T, bool>> filter)
{
    LambdaExpression targetFilter = filter;
    if (target.ClrType != typeof(T))
    {
        var parameter = Expression.Parameter(target.ClrType, "e");
        var body = filter.Body.ReplaceParameter(filter.Parameters[0], parameter);
        targetFilter = Expression.Lambda(body, parameter);
    }
    target.AddQueryFilter(targetFilter);
}

```

It's a generic method - not quite type-safe, but allows you to use a compile time lambda expression and bind it to the actual entity type as follows:



```
foreach (var entityType in modelBuilder.Model.GetEntityTypes())
{
    if (typeof(IDeleted).IsAssignableFrom(entityType.ClrType))
        entityType.AddQueryFilter<IDeleted>(e => e.DateTimeDeleted == null);
}

```

Looks better, isn't it :)


The last custom extension method is complement to (replacement of) the standard EF Core generic [`HasQueryFilter`](https://docs.microsoft.com/en-us/dotnet/api/microsoft.entityframeworkcore.metadata.builders.entitytypebuilder-1.hasqueryfilter?view=efcore-2.1#Microsoft_EntityFrameworkCore_Metadata_Builders_EntityTypeBuilder_1_HasQueryFilter_System_Linq_Expressions_Expression_System_Func__0_System_Boolean___) method:



```
public static EntityTypeBuilder<TEntity> AddQueryFilter<TEntity>(this EntityTypeBuilder<TEntity> target, Expression<Func<TEntity, bool>> filter)
    where TEntity : class
{
    target.Metadata.AddQueryFilter(filter);
    return target;
}

```

and allows you to replace



```
this.AddToDict<DbMyEntity>(t => t.Name == null || t.Name == "Something");

```

with the more convenient



```
modelBuilder.Entity<DbMyEntity>()
    .AddQueryFilter(t => t.Name == null || t.Name == "Something");

```

**Update (EF Core 3.0):** `QueryFilter` property has been replaced with `GetQueryFilter` and `SetQueryFilter` extension methods. is this a euphemism? i'm guessing she's a bit envious of you because she knows she should be exercising but isn't. that would explain why she shuts you down quickly by changing the topic. it's something she doesn't want to deal with.

remember that you don't need her approval or encouragement. it would be nice to have but she can't do that for you when it comes to your running success. 

good luck with the 1/2 marathon! an unfair equating of intent to commit a felony and intent to commit murder if e is any event associated with an experiment, then
