Getting error as "Key... already registered in container"

[Bhagwat Mane]

Hi All,

I am getting error as "Key 'SolrNet.Impl.SolrConnection.SolrSearchResult.SolrNet.Impl.SolrConnection' already registered in container".

after searching on web, i found that we can resolve this issue by putting Startup.Init code in global.asax in web application and for windows in main() function.

Below are my points-

1. We have created separate dll for solr code as we are using this component from multiple places.
2. We have one more requirement that we need to change solr url at run time, as we are doing some operation at same time with multiple environments. and those environments have different solr servers.
3. In our application we are doing some operations in multi threading and at that time this solr code get execute. some time we face above error with multi threading.

Please help me to resolve this error, how i can change url at runtime?

Thanks,

Bhagwat Mane

Thank You.

You could either:

- create a cache of ISolrOperations instances per URL (e.g. using ConcurrentDictionary) or 

- not use Startup.Init and instead create all the internal SolrNet objects yourself. You can use https://github.com/mausch/SolrNet/blob/master/SolrNet/Startup.cs as reference.

Thanks for sharing your feedback on this.

In our case as mentioned above by Bhagwat , we are not using Dictionary for saving details so would not be able to use  ConcurrentDictionary.

For the second option, can you please elaborate more how can we create all the internal SolrNet objects ?

Thanks!
