RemoteInstance values with single quotes fail to deserialize from v5 onwards

[jpalac]

Describe the bug

Description

RemoteIntance values are stored in the config file using single quotes:

<configuration>
  <appSettings>
    <add key="ServiceControl/RemoteInstances" value="[{'api_uri':'http://localhost:33334/api'}]"/>
  </appSettings>/
</configuration>

From SC version 5 Newtonsoft.Json has been replaced with System.Text.Json and that does not support single quotes.

When a new SC installer runs, it checks for other instances already installed and tries to read the config file. This fails if the config file has RemoteInstances listed using single quotes.

Expected behavior

New instance is installed successfully, even if other instances exist.

Versions

ServiceControl V5+

Steps to reproduce

• Install ServiceControl (any version)
• Update the config file to have single quotes in the RemoteInstance value
• Install a new instance of ServiceControl v5+
• The installation will fail

Relevant log output

Additional Information

Workarounds

Before installing a new instance, update the config file of any other instances that are using single quotes for RemoteInstance value or setting to use " instead of the single quote

<configuration>
  <appSettings>
    <add key="ServiceControl/RemoteInstances" value="[{&quot;api_uri&quot;:&quot;http://localhost:33334/api&quot;}]"/>
  </appSettings>/
</configuration>
