您尝试打开的工作区与当前的 dotMemory 版本不兼容

Question

我已经使用 .Net 5 目标框架创建了一个新的 XUnit 测试项目并进行了一次测试 class

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（运行在 dotMemory Unit 下）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)

当我用 .dmw 文件点击 link 时，dotmemory 应用程序被打开

当前应用版本和许可信息

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.

并出现对话框 window

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 select 是，则打开 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？

Answer 1

.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 产生了一个旧格式的工作空间，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，您可以使用试用期。而 dotMemory 2019.1.3 的试用期在您的机器上已经结束。 dotMemory 任何版本的付费许可肯定涵盖所有以前的版本。
