使用生成类型提供程序创建多个根类型

Question

生成类型提供程序似乎在具有多个根类型方面存在问题。 完整的复现代码可以在此处找到：https://gist.github.com/dsevastianov/46d1a8495c4af46a9875。以下是一个示例：

#r @"SampleProvider.dll"
type Birch = Sample.Sample<"birch">
type Elm = Sample.Sample<"elm">

let birch = Birch.birch()
let elm = Elm.elm()
elm.Branches <- ([|Elm.elm()|])

在编译时失败（而不是设计时）：

FSC: error FS2014: A problem occurred writing the binary 'obj\Debug\Tests.dll': 
Error in pass3 for type Schema, error: Error in GetMethodRefAsMethodDefIdx for 
mref = (".ctor", "ZipLookup"), error: Exception of type Microsoft.FSharp.Compiler.AbstractIL.ILBinaryWriter+MethodDefNotFound' was thrown.

原来需要为每个根类型创建单独的临时程序集。我修改了代码片段以反映解决方案：https://gist.github.com/dsevastianov/46d1a8495c4af46a9875。
