您尝试打开的工作空间与当前dotMemory版本不兼容

Question

我已经使用.Net 5目标框架和一个测试类创建了一个新的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包为JetBrains.DotMemoryUnit 3.1.20200127.214830

在运行测试(在dotMemory单元下运行)之后，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)

当我点击带有.dmw文件的链接时，将打开dotmemory应用程序

当前应用程序版本和许可证信息

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.

和对话框窗口出现

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?

如果选择是，则会打开dotMemory 2019.1.3，并显示有关许可信息已结束的对话框(我的许可仅适用于2020.3)

那么为什么.dmw文件不支持dotMemory 2020.3.3呢？

Answer 1

为了给用户提供新的功能，.dmw文件格式经常被改变。不幸的是，dotMemory单位生产了一个旧格式的工作区，因为新版本已经有几年没有发布了。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的试用期在您的机器上已经结束。任何版本的dotMemory的付费许可肯定涵盖了所有以前的版本。
