我创建了一个带有 .Net 5 目标框架和一个测试类的新 XUnit 测试项目

public class SomeTests
{
    private readonly ITestOutputHelper output;

    public SomeTests(ITestOutputHelper output)
    {
        this.output = output;
        DotMemoryUnitTestOutput.SetOutputMethod(output.WriteLine);
    }

    [Fact]
    [DotMemoryUnit(CollectAllocations = true)]
    public void SomeTest()
    {
        var beforeTestMethodPoint = dotMemory.Check();
        var allocatedArray = new string[10];
        dotMemory.Check(afterTestMethodPoint => Assert.True(afterTestMethodPoint.GetTrafficFrom(beforeTestMethodPoint).AllocatedMemory.SizeInBytes == 0));
    }
}

安装的 NuGet 包是 JetBrains.DotMemoryUnit 3.1.20200127.214830

运行测试后（在 dotMemory Unit 下运行），将创建以下输出

Xunit.Sdk.TrueException
Assert.True() Failure
Expected: True
Actual:   False
   at TestsDotMemory.SomeTests.<>c__DisplayClass2_0.<SomeTest>b__0(Memory afterTestMethodPoint) in SomeTests.cs:line 25
   at JetBrains.dotMemoryUnit.dotMemory.Check(Action`1 check)
   at TestsDotMemory.SomeTests.SomeTest() in SomeTests.cs:line 25


[dotMemory Unit]: The workspace is saved to "file:///C:/Users/username/AppData/Local/Temp/dotMemoryUnitWorkspace/Run-2021-03-06T10-15-06.288/SomeTest.2021-03-06T10-15-11.629.dmw". (File size: 9 MB)

当我单击带有 .dmw 文件的链接时，dotmemory 应用程序已打开

当前应用程序版本和许可信息

JetBrains dotMemory 2020.3.3 Build 203.0.20210217.101844 built on 2021-02-17
dotMemory 2020.3.20210217.101844
dotMemory 2020.3.3 free trial period is running. 2 days left.

并出现对话窗口

The workspace you are trying to open is incompatible with the current dotMemory version. Do you want to open the workspace in a compatible portable dotMemory version?

如果我选择是，则会打开 dotMemory 2019.1.3，并显示有关许可证信息的对话框已结束（我的许可证仅适用于 2020.3）

那么为什么 dotMemory 2020.3.3 不支持 .dmw 文件呢？

.dmw 文件格式经常更改，以便为用户提供新功能。不幸的是，dotMemory Unit 以旧格式生成工作空间，因为新版本已经好几年没有发布了。据我所知，您没有 dotMemory 2020.3 的许可证，您使用的是试用期。而 dotMemory 2019.1.3 的试用期已在您的计算机上结束。任何版本的 dotMemory 的付费许可证肯定涵盖所有以前的版本。
