DougMurphy.TargetFrameworks.EndOfLife 2.1.1

Introduction

Knowing if your Target Framework Moniker (TFM) is End of Life (EOL) or not can be very important in certain circumstances. Maybe your company requires using supported target frameworks for compliance reasons, maybe you're publishing a NuGet package and want to make sure you're only supporting frameworks that Microsoft supports, or maybe you just want to make sure you're staying up-to-date. No matter the reason, this NuGet package can help you out with that.

Methods

GetAllEndOfLifeTargetFrameworkMonikers

By default, this method will get all TFMs that are currently EOL. Two overloads are provided where you can either pass in an explicit DateTime to get all TFMs that will be EOL by that date, or a TimeframeUnit with an amount to forecast out to a date relative to current date.

CheckTargetFrameworkForEndOfLife

This method takes in a singular TFM or semicolon-delimited pluralized TFM and returns back which one(s), if any, of them are currently EOL.

Example Usage

Checking if a specific TFM is EOL

using DougMurphy.TargetFrameworks.EndOfLife.Enums;
using DougMurphy.TargetFrameworks.EndOfLife.Helpers;
using DougMurphy.TargetFrameworks.EndOfLife.Models;
using System;
using System.Collections.Generic;

public void CheckIfSingleTfmIsEol() {
    var tfm = "net5.0";
    TargetFrameworkCheckResponse endOfLifeResults = TargetFrameworkEndOfLifeHelper.CheckTargetFrameworkForEndOfLife(tfm);

    if (endOfLifeResults.EndOfLifeTargetFrameworks.Count == 0) {
        //the specified TFM is not EOL
    }
    else {
        //the specified TFM is EOL
        foreach (KeyValuePair<string, DateTime> endOfLifeTargetFramework in endOfLifeResults.EndOfLifeTargetFrameworks) {
            Console.WriteLine($"{endOfLifeTargetFramework.Key} has an EOL date of {endOfLifeTargetFramework.Value}");
        }
    }
}

public void CheckIfAnyOfMultipleTfmIsEol() {
    var tfm = "net5.0;net45";
    TargetFrameworkCheckResponse endOfLifeResults = TargetFrameworkEndOfLifeHelper.CheckTargetFrameworkForEndOfLife(tfm);

    if (endOfLifeResults.EndOfLifeTargetFrameworks.Count == 0) {
        //none of the specified TFMs are EOL
    }
    else {
        //at least one of the specified TFMs are EOL
        foreach (KeyValuePair<string, DateTime> endOfLifeTargetFramework in endOfLifeResults.EndOfLifeTargetFrameworks) {
            Console.WriteLine($"{endOfLifeTargetFramework.Key} has an EOL date of {endOfLifeTargetFramework.Value}");
        }
    }
}

public void CheckIfSingleTfmIsEolWithinThreeMonths() {
    var tfm = "net5.0";
    TargetFrameworkCheckResponse endOfLifeResults = TargetFrameworkEndOfLifeHelper.CheckTargetFrameworkForEndOfLife(tfm, TimeframeUnit.Month, 3);

    if (endOfLifeResults.EndOfLifeTargetFrameworks.Count == 0) {
        //the specified TFM is not EOL
    }
    else {
        //the specified TFM is EOL
        foreach (KeyValuePair<string, DateTime> endOfLifeTargetFramework in endOfLifeResults.EndOfLifeTargetFrameworks) {
            Console.WriteLine($"{endOfLifeTargetFramework.Key} has an EOL date of {endOfLifeTargetFramework.Value}");
        }
    }
}

public void CheckIfAnyOfMultipleTfmIsEolWithinThreeMonths() {
    var tfm = "net5.0;net45";
    TargetFrameworkCheckResponse endOfLifeResults = TargetFrameworkEndOfLifeHelper.CheckTargetFrameworkForEndOfLife(tfm, TimeframeUnit.Month, 3);

    if (endOfLifeResults.EndOfLifeTargetFrameworks.Count == 0) {
        //none of the specified TFMs are EOL
    }
    else {
        //at least one of the specified TFMs are EOL
        foreach (KeyValuePair<string, DateTime> endOfLifeTargetFramework in endOfLifeResults.EndOfLifeTargetFrameworks) {
            Console.WriteLine($"{endOfLifeTargetFramework.Key} has an EOL date of {endOfLifeTargetFramework.Value}");
        }
    }
}

Getting a list of TFMs that are currently EOL, or will be within a specified forecasted timeframe

using DougMurphy.TargetFrameworks.EndOfLife.Enums;
using DougMurphy.TargetFrameworks.EndOfLife.Helpers;
using DougMurphy.TargetFrameworks.EndOfLife.Models;
using System;
using System.Collections.Generic;

public void GetAllTfmsThatAreEol() {
    TargetFrameworkCheckResponse endOfLifeResults = TargetFrameworkEndOfLifeHelper.GetAllEndOfLifeTargetFrameworkMonikers();

    foreach (KeyValuePair<string, DateTime> endOfLifeTargetFramework in endOfLifeResults.EndOfLifeTargetFrameworks) {
        Console.WriteLine($"{endOfLifeTargetFramework.Key} has an EOL date of {endOfLifeTargetFramework.Value}");
    }
}

public void GetAllTfmsThatAreEolWithinOneYear() {
    //Get all EOL TFMs that are currently EOL, or will be EOL within 1 year of current date.
    TargetFrameworkCheckResponse endOfLifeResults = TargetFrameworkEndOfLifeHelper.GetAllEndOfLifeTargetFrameworkMonikers(TimeframeUnit.Year, 1);

    foreach (KeyValuePair<string, DateTime> endOfLifeTargetFramework in endOfLifeResults.EndOfLifeTargetFrameworks) {
        Console.WriteLine($"{endOfLifeTargetFramework.Key} has an EOL date of {endOfLifeTargetFramework.Value}");
    }
}
