DbContext isn't thread safe and isn't designed for concurrent use.
To handle multi-threads scenarios, use a AddDbContextFactory to create a DbContext for each query.
| Program.cs
|
builder.Services.AddDbContextFactory<MyDbContext>();
|
| MyRepository.cs
|
private readonly IDbContextFactory<MyDbContext> contextFactory;
public DataSummaryRepository(IDbContextFactory<MyDbContext> contextFactory)
{
this.contextFactory = contextFactory;
}
public async Task<Data> FetchDataAsync()
{
// create a DbContext for this query, then dispose it once the query has been executed
using var context = contextFactory.CreateDbContext();
}
