# IDbContextFactory
|
|
|
|
The goal of this project is to help, fill the gap of supporting multiple ORM's in DynamicQuery, and possibly more projects in the future.
|
|
|
|
One of the most obvious reason is to be able to execute async/await operations on the context without, the executing library to be dependant on the ORM Framework such as (EF Core, EF6).
|
|
|
|
## Getting Started
|
|
|
|
> Install nuget package to your awesome project.
|
|
|

|
# In your application you may do the following
|
|
|
|
```csharp
|
|
public class Startup
|
|
{
|
|
public void ConfigureServices(IServiceCollection services)
|
|
{
|
|
// for mongo.
|
|
services.AddPoweredSoftMongoDBDataServices();
|
|
|
|
// for ef core
|
|
services.AddPoweredSoftEntityFrameworkCoreDataServices();
|
|
}
|
|
}
|
|
```
|
|
|
|
> Then somewhere else.
|
|
|
|
```csharp
|
|
public class SomeClass
|
|
{
|
|
private readonly IDbContextFactory contextFactory;
|
|
public SomeClass(IDbContextFactoryProvider dbContextFactoryProvider)
|
|
{
|
|
contextFactory = dbContextFactoryProvider.GetContextFactory(typeof(YourFavoriteContext));
|
|
}
|
|
}
|
|
|
|
```
|
|
|
|
## AsyncQueryableFactory
|
|
|
|
Also as the same kind of goal, will slowly add support for a non dependant to orm async method.
|
|
|
|
```csharp
|
|
public interface IAsyncQueryableHandlerService
|
|
{
|
|
Task<T> FirstOrDefaultAsync<T>(IQueryable<T> queryable, CancellationToken cancellationToken = default(CancellationToken));
|
|
Task<T> FirstOrDefaultAsync<T>(IQueryable<T> queryable, Expression<Func<T, bool>> predicate, CancellationToken cancellationToken = default(CancellationToken));
|
|
Task<List<T>> ToListAsync<T>(IQueryable<T> queryable, CancellationToken cancellationToken = default(CancellationToken));
|
|
Task<int> CountAsync<T>(IQueryable<T> queryable, CancellationToken cancellationToken = default(CancellationToken));
|
|
Task<long> LongCountAsync<T>(IQueryable<T> queryable, CancellationToken cancellationToken = default(CancellationToken));
|
|
Task<bool> AnyAsync<T>(IQueryable<T> queryable, Expression<Func<T, bool>> predicate, CancellationToken cancellationToken = default(CancellationToken));
|
|
Task<bool> AnyAsync<T>(IQueryable<T> queryable, CancellationToken cancellationToken = default(CancellationToken));
|
|
bool CanHandle<T>(IQueryable<T> queryable);
|
|
}
|
|
```
|
|
|
|
How to use
|
|
|
|
```csharp
|
|
public class SomeClass
|
|
{
|
|
private readonly IAsyncQueryableService asyncQueryableService;
|
|
public SomeClass(IDbContextFactoryProvider asyncQueryableService)
|
|
{
|
|
this.asyncQueryableService = asyncQueryableService;
|
|
}
|
|
|
|
public async Task<T> GetFirstAsync(IQueryable<T> query) {
|
|
return await this.asyncQueryableService.FirstOrDefaultAsync(query);
|
|
}
|
|
}
|
|
|
|
```
