Introduction

The End of Life API is an Azure Functions project written to be a single source of truth that can be used programmatically to determine whether or not a particular Target Framework Moniker (TFM) is end of life (EOL). It provides a very simple, yet fully feature-encompassing set of endpoints. Both the legacy csproj TFM style (eg. v4.5) and the newer SDK-style csproj TFM style (eg. net45) are supported.

Endpoints

/api/check-eol/:tfm

This endpoint checks if the specific TFM is EOL or not. The TFM argument can be a single TFM or a semicolon-delimited list. If none of the specified TFM's are EOL, this will return 204-No Content. If any of the specified TFM's are EOL, then any EOL TFM of those specified will be returned in a JSON object with an array named EndOfLifeTargetFrameworks.

Example: When passing net45;net6.0 for the TFM.

{
    "EndOfLifeTargetFrameworks": {
        "net45": "2016-01-12T00:00:00"
    }
}

/api/get-all-eol?timeframeUnit=<enum>&timeframeAmount=<byte>

This endpoint will return a JSON object with an array named EndOfLifeTargetFrameworks containing all TFM's that are currently EOL, or will be EOL within the (optional) query-string parameter timeframe. The results are sorted alphabetically to provide easier manual parsing.

    "EndOfLifeTargetFrameworks": {
        "net11": "2011-07-12T00:00:00",
        "net20": "2011-07-12T00:00:00",
