为了让它发挥作用,我尝试添加Roslyn codedom nuget包,但这会产生两个问题
第一个问题是,它在错误的位置\bin\debug\bin\roslyn\vbc.exe查找编译器,而构建过程实际上在文件夹\bin\debug\roslyn\中创建编译器。有谁能告诉我如何解决这个问题,因为我的构建服务器部署失败了
制作roslyn文件夹的手动副本并将其放置在codedom希望找到的位置并非真正的解决方案,但这会引发第二个问题,即它希望导入System.Web.HttpRequest和System.Web.HttpResponse。但是我没有编译任何与web相关的winforms代码。那么,为什么它会期望这样呢?没有任何承诺,但我有一个类似的问题,通过将我正在升级的这些行包括在website.vbproj中的现有项目中来解决。他们应该包括在nuget中
