dotnet build指定main方法

Question

我dotnet用来从命令行构建一个.NET Core C#项目.该项目有多个带有main方法的类.因此我得到错误:

$ dotnet build
Microsoft (R) Build Engine version 15.1.548.43366
Copyright (C) Microsoft Corporation. All rights reserved.

Test.cs(18,28): error CS0017: Program has more than one entry point defined. Compile with /main to specify the type that contains the entry point.

Build FAILED.

传递/main开关会导致错误:

$ dotnet build /main:Test
Microsoft (R) Build Engine version 15.1.548.43366
Copyright (C) Microsoft Corporation. All rights reserved.

MSBUILD : error MSB1001: Unknown switch.
Switch: /main:Test

如何将/main开关传递给dotnet命令？

Answer 1

您可以编辑csproj来定义要使用的类(在a中PropertyGroup):

<StartupObject>foo.Program2</StartupObject>

或者通过以下命令在命令行中指定此MSBuild属性:

$ dotnet build foo.csproj /p:StartupObject=foo.Program2
