    ABP has an experimental MongoDB implementation: https://github.com/aspnetboilerplate/aspnetboilerplate/tree/dev/src/Abp.MongoDB

    Looking for something production ready as experimental won't get approved for deployments. If Ed core supports other dbs what's the issue with running it via entity framework core directly to cosmosdb? Using document db API

    If you read my link on EF Core Database Providers, you would know that EF Core doesn't support NoSQL databases. It is also unlikely for AspNet Zero to go huge into NoSQL.

    See this link for Azure Cosmos DB: https://docs.microsoft.com/en-us/azure/cosmos-db/documentdb-dotnetcore-get-started

    Here is a framework which maps EF Core to Mongo DB. <a class="postlink" href="https://github.com/crhairr/EntityFrameworkCore.MongoDb">https://github.com/crhairr/EntityFrameworkCore.MongoDb</a>

    My assumption it can be added as is, and then we should be able to configure asp.net zero database to use mongodb.

    Please advise?

    hi

    apart from technical issues;

    In the Microsoft / .NET microservices - Architecture book, it says this;

    When you use NoSQL databases for your infrastructure data tier, you typically do not use an ORM like Entity Framework Core. Instead you use the API provided by the NoSQL engine, such as Azure Cosmos DB, MongoDB, Cassandra, RavenDB, CouchDB, or Azure Storage Tables.

    We plan to give it a try to that EF to Mongo mapping.

    Not sure I would believe everything microsoft says.

    The exception stack shows that the last error line in AspNet Zero layer is -> DbContextEfCoreTransactionStrategy.CreateDbContext(...)

    So what I see here is, this provider doesn't support transactions. You can try out disabling transactions on application level. See the below config;

    [DependsOn(
	typeof(AbpZeroCoreEntityFrameworkCoreModule),
	typeof(AbpZeroTemplateCoreModule),
	typeof(AbpZeroCoreIdentityServerEntityFrameworkCoreModule)
	)]
public class AbpZeroTemplateEntityFrameworkCoreModule : AbpModule
{
	public override void PreInitialize()
	{
	   // ....
	   // add this line to disable transactions
		Configuration.UnitOfWork.IsTransactional = false;
	   // ....
	}
	
	//........
}

    good luck ;)

    In my solution I've created a new module to use MongoDb with BsonDocument.

    You need to pay attention to UOW and you need to create a wrapper to Repository Method. In the wrapper you need to use Query (native MongoDb).

    I my experince is quite simple use MongoDb to serialize large object or entity where Json/mongodb(nosql) is the best solution and MSSQL (via EF for classic entity like user, bank, customer). This mix give you the best off 2 soultion

    It's mandatory for my project the use of mongo-db. :cry:

    Can I change the datastore at repository level? Have you a document about what I need to implement? I know that without EF I'll lose entity history and transactions.

    @jollyticket - If you want all of your data in Mongodb why not cut into EntityHistory functionality and serialize the results using the .net Mongodb driver? That way all of your data will be in Mongodb and your relational stuff will be where it should be, in a relational database? Just a suggestion but it may give you a different direction of thinking because I think you will be pulling your hair out trying to get a system out with an unsupported solution????

    @jollyticket, @BobIngham is right, AspNet Zero doesn't support MongoDB. So if you try to use AspNet Zero with MongoDb (I'm not sure if it is possible at all), you will loose quite amount of time I think.

    Also EntityFramework doesn't support MongoDB officially, so I think it is not good to build a product on a library which is not officially supported.

    Probably the best way to close this post is to write that <ins>aspnetzero does NOT support no-sql databases</ins> like mongodb, rather than giving directions or suggestions on impossible implementations.

    The fact remains that this is a splendid framework for everything else

    Jeepers, @ jollyticket - aspnetzero is PERFECT for no-sql databases. Serialisation of EntityHistory gives you the initial document and every change thereafter gives an additional document. You could even throw the the serialised result on to a command bus to give you CQRS. If the result of your project has to be a Mongodb database (and I can understand why that may be) and the start point has to be aspnetzero then this is the way to go. Leave the relational database where it is, it is serving the purpose it is designed for. Don't re-invent the wheel.

    ... and don't over-engineer.

    Good luck on that deadline, I hope it all works out for you!

    @jollyticket,

    aspnetzero does NOT support no-sql databases officially for storing it's built-in entities/tables would be better :). Because you can store your new entities in MongoDB.
