Build of solution fails #59

Closed mbabramo closed 5 years ago

mbabramo commented 6 years ago

A clone of the CodeGeneration.Roslyn solution failed to build. (I tried this both in Visual Studio 15.5.7 and the current preview of Visual Studio.) The Errors List shows the following error:

I also tried running against sdk 2.1.4, and I received a similar error. I decided to try to go back to 1.1.8, but then sensibly received the error, "The version of Microsoft.NET.Sdk used by this project is insufficient to support references to libraries targeting .NET Standard 1.5 or higher. Please install version 2.0 or higher of the .NET Core SDK."

Finally, I thought I found the sweetspot with sdk 2.0.2. This at least discovers the project tests and avoids the errors above. But then I received another error: "The process cannot access the file 'C:\Users\mbabr\source\repos\CodeGeneration.Roslyn\bin\CodeGeneration.Roslyn.Tasks\Debug\net45\CodeGeneration.Roslyn.Tasks.dll' because it is being used by another process."

@mbabramo The first error:

C:\Program Files\dotnet\sdk\2.1.300-preview1-008174\Microsoft.Common.CurrentVersion.targets(1126,5): error MSB3644: The reference assemblies for framework ".NETFramework,Version=v2.0" were not found. To resolve this, install the SDK or Targeting Pack for this framework version or retarget your application to a version of the framework for which you have the SDK or Targeting Pack installed. Note that assemblies will be resolved from the Global Assembly Cache (GAC) and will be used in place of reference assemblies. Therefore your assembly may not be correctly targeted for the framework you intend.

is expected if you didn't have .NET Framework 2.0 SDK installed - the CodeGeneration.Roslyn.Attributes project has net20 target among multiple others, and so to build it you need corresponding SDK.

The second error:

"The process cannot access the file 'C:\Users\mbabr\source\repos\CodeGeneration.Roslyn\bin\CodeGeneration.Roslyn.Tasks\Debug\net45\CodeGeneration.Roslyn.Tasks.dll' because it is being used by another process."

is actually a common problem that I don't know how to permanently resolve (@AArnott ?), but a typical workaround is to kill all MSBuild.exe processes:

For some reason one MSBuild instance locks said dll and other instances can't access it.

Closing as deprecated. Project went through major refactor, documentation was updated.
