Description

There are two alternative ways to make MongoDB Atlas work with xConnect.

Solution

• Use an old-formatted connection string (without "+srv"). For example:

  mongodb://sa:12345@cluster0-shard-00-00-test.mongodb.net:27017,cluster0-shard-00-01-test.mongodb.net:27017,cluster0-shard-00-02-test.mongodb.net:27017/test?ssl=true&replicaSet=Cluster0-shard-0&authSource=admin&retryWrites=true&w=majority

• For SRV connection strings, add a binding redirect under the <assemblybinding> section in the Web.config file of xConnect:

  <dependentAssembly>
    <assemblyIdentity name="System.Buffers" publicKeyToken="cc7b13ffcd2ddd51" culture="neutral"/>
    <bindingRedirect oldVersion="0.0.0.0-4.0.2.0" newVersion="4.0.3.0"/>
  </dependentAssembly>

Note: For both of these ways it is necessary to use &amp; instead of & to separate parameters in the xConnect connection string. For example:

instead of:

mongodb+srv://sa:12345@cluster0-test.mongodb.net/test?retryWrites=true&w=majority

use the following:

mongodb+srv://sa:12345@cluster0-test.mongodb.net/test?retryWrites=true&w=majority
