[MongoDB.Driver] some methods throw exception after native compiler

[Jaafar-abusair]

Hi,

some methods throw exception after native compiler [MongoDB.Driver] and some of them are working fine
The ones listed below are not working when calling them

using "dotnet publish -c Release -r win-x64", i get this errors on build

Not sure which label i should add to the ticket

Generic exceptions https://github.com/mongodb/mongo-csharp-driver/blob/master/src/MongoDB.Driver/MongoCollectionBase.cs#L245

This is #67806

[Jaafar-abusair]

@jkotas thank you for your replay, is there anything to do from my side?

[jkotas]

The only way to workaround this issue is to avoid catch with a generic exception type. You can do that by e.g. changing catch (MongoBulkWriteException<TDocument> ex) to catch (Exception ex) when (ex is MongoBulkWriteException<TDocument>). The fix we need to implement for #67806 is to do this transformation in the AOT compiler.

But im not the owner of MongoDriver, i'm just using the it, can i do that from my side?

this is what i get when it get called

System.AggregateException: One or more errors occurred. (Common Language Runtime detected an invalid program.) ---> System.InvalidProgramException: Common Language Runtime detected an invalid program. at Internal.Runtime.TypeLoaderExceptionHelper.CreateInvalidProgramException(ExceptionStringID) + 0x31 at Internal.Runtime.CompilerHelpers.ThrowHelpers.ThrowInvalidProgramException(ExceptionStringID) + 0x9 at MongoDB.Driver.MongoCollectionBase1.d__101.MoveNext() + 0xe

[jkotas]

There is nothing you can do about it from your side without changing the MongoDriver.

[Jaafar-abusair]

Do you know when it could be possible from your side, i mean supporting generic exception?

[jkotas]

I am not sure when we get to fixing this.

[Jaafar-abusair]

Thanks buddy

We will try to fix this in .NET 7.
