The latest v3.0 release of the FuseIT SFDC Explorer now supports TLS 1.1 and 1.2. This was required as Salesforce will be disabling TLS 1.0 via critical updates available in Spring '16.
Part of this was to upgrade to the .NET Framework 4.6.1 to get native support for the newer TLS versions. You can get the .NET Framework 4.6.1 installer from https://www.microsoft.com/en-us/download/details.aspx?id=49981. Note that it does need to be 4.6.1, the 4.6 installer won't work.
Without this version you are likely to get an error like the following when attempting to login:
UNSUPPORTED_CLIENT: TLS 1.0 has been disabled in this organization. Please use TLS 1.1 or higher when connecting to Salesforce using https.
Other notable changes:
- Update ApexLog parsing to allow for Spring '16 date formats
- Wsdl2Apex: Add basic WSDL schema validation and reporting via error messages. Detect potential WSDL 1.1 structure issues.
- Wsdl2Apex: Apex variable names can't start with an underscore. Will be prefixed with 'x'
