多实例问题 - .NET 框架 4.8 WPF 应用程序到 .NET5 [英] Multiple instance issue - .NET framework 4.8 WPF application to .NET5

问题描述

当我尝试将我的 WPF 应用程序转换为 .NET 5 时.我得到以下信息.

When I am trying to convert my WPF application to .NET 5. I am getting the following below.

有人可以指导我吗?

C:WINDOWSsystem32>try-convert -p "D:ClientNewRoutinesRoutines.csproj"
Multiple installs of MSBuild detected please select one:
Instance 1
    Name: .NET Core SDK
    Version: 5.0.302
    MSBuild Path: C:Program Filesdotnetsdk5.0.302
Instance 2
    Name: .NET Core SDK
    Version: 2.1.524
    MSBuild Path: C:Program Filesdotnetsdk2.1.524
Instance 3
    Name: .NET Core SDK
    Version: 2.1.202
    MSBuild Path: C:Program Filesdotnetsdk2.1.202

我也跟着多次安装MSBuild 但帮助不大.

I also followed Multiple installs of MSBuild but not much of help.

我还安装了 upgrade-assistant 并且现在尝试使用这个命令.我收到 Required command is not provided 错误:

I also installed upgrade-assistant and now trying to use this command. I am getting Required command was not provided error:

C:Users
yaTest>upgrade-assistant C:Users

Required command was not provided.
Unrecognized command or argument 'C:Users

推荐答案

这似乎是因为转换工具想知道要使用哪个版本的 MSBuild.

It appears as though this is because the conversion tool is wanting to know which version of MSBuild to use.

这个问题:Dotnet项目转换试试-convert 当多次安装 MSBuild" 有一些关于如何指示工具应该使用哪个版本的信息时会失败，尽管它目前还没有被接受的答案.

This question: Dotnet project conversion try-convert fails when "Multiple installs of MSBuild" has some information on it about how to indicate which version the tool should use, although it doesn't have an accepted answer as yet.
